Dell Latitude laptop fails to boot on A/C power

posted in: Boot Problems | 73

I have a Dell Latitude CPi R laptop. This laptop fails to boot on A/C power as well as battery power. When I switch on the laptop the power light comes on and the hard drive light blinks once and after 2-3 seconds the system shuts down. The display never comes up nor does the system fan start. In case of a floppy drive inside I can hear the click sound of it trying to access the drive just before the laptop shuts down. I completely disassembled the laptop and checked all the connections thoroughly but the problem remains.

I would test the AC adapter first. I think it’s possible that the adapter is bad and the battery is discharged. Try to remove the battery, plug in the AC adapter and start the laptop without the battery installed. Then I would try to install a test memory module or at least reseat it. Does is make any difference?
If nothing helps, you can minimize the system as much as possible and try to start it with an external monitor. Normally you need only 3 components to successfully boot a laptop and see if you have some basic functionality. These components are the system board, the CPU and the memory module. Leave only these three components and connect an external monitor. Now try turn on the laptop. You should a video on the external monitor. If you still have no video and the system still shuts down, then one of the three components is bad. I would try to swap the memory first and if it doesn’t help then most likely you have a bad system board.
About 2 weeks ago I had to repair a HP laptop with similar problems. I was able bring it back to live after I reseated the video cable on the LCD screen. The cable was half way out.

  1. I have the same kind of problem. Which I solve by pressing hard on the center of the keyboard while pushing the power button (when it boots, release keyboard). Most of the time it works well but sometimes the internal LAN card get disabled.

  2. I have the same problem. There is nothing wrong with the adapter or battery. I tried pressing on the keepboard and the fan and harddrive turned on, but It shut down within 2-3 seconds like usual. It still powers down when I connect my computer monitor to it with the LCD cable unplugged from the system board. I checked the CPU and it seems ok. I reseated the memory, still nothing. The only thing that gets it starting up is pressing hard on the keep board but thats still only 3 seconds and when it starts up theirs still no video on screen. Any solutions?

    Clayton,
    Will you get video if you start the laptop without the hard drive? If the RAM and CPU are good but the laptop still will not boot with internal or external video even after you removed the hard drive, then I would say you have a bad motherboard, not sure what else could be wrong.

  4. i have a problem with my gateway 450sx4. it doesnt boot at all and ac adapter is fine, bought new battery, cpu looks fine, swapped ram. im thinking about ordering a new motherboard for it, will that require any soldering? if not im pretty sure i can do it myself, thanks.

  5. Laptop Freak

    Dan,
    Replacing the motherboard will not require any soldering. You’ll have to disassemble the laptop, remove the old motherboard, transfer everything to the new motherboard (CPU, heat sinks, RAM, etc…) and assemble the laptop.

  6. i have a dell latitude cpi laptop and when ever i turn it on i has a seconfd of nothing then it will flash while beepig 8 times after 8 times it turns it self off what shall i do

    my laptop dell inspiron wont start when i press the power button, the led switches on for a few seconds then it goes off. both the fans and the lcd dont light up. when i plug the power supply the led flashes in invervals of a bout 10 seconds. can you help me

  8. Laptop Freak

    masauso-sau ,
    Remove the battery and start the laptop from AC without battery installed. Same problem?
    May be you have a faulty power supply? You’ll have to find a known good AC adapter and test the laptop. If you still have the same problem even with a good adapter, probably there is something wrong with the motherboard.

  9. I have a case of these Dell CPi’s, They seem to have two problems, either “A” I get two of the three leds light up stay on for five seconds and shut off. or “B” it beeps three times and pauses and does it again. This is a memory problem, now it may not be the stick itself but it is a problem in the memory circut. It comes down to the unit, If you open your memory cover, and look at your bios chip, if it says a bunch of numbers and then “T” your done for. If it says “B” you have half a chance. This distinction in the chip goes to the video board as well as a few other aspects of the laptop. For further reference you can not put an LCD from a “B” on to a “T” they are not compatible, it won’t turn on until you un plug it.

  10. Thanks alot UpGrade for the info,

    Mine has a “T” on the bios chip, is there any solution for the problem? If not, what should I do with the laptop? Thanks again.

    I have a Dell Inspiron 1150….My problem is when I have the battery in and I try to boot up(press power button), I get the power and charge LEDs but nothing happens. No fan no nothing, and I can only make the lights go off by removing the battery. If I plug into AC power same thing. When I remove the battery and just go AC power alone, the power and charge lights just come on without me doing anything(pressing the power button, ect.) but still nothing happens…..HELP!

  12. My problem is similar to those mentioned. More specific similar to Brians problem. It is a dell latitude cpi. Tested all as described above. Tore the little bugger apart to check cable connectors, etc. On AC power, when I press the power button, the unit flashes power indicator light and you can see a faint flicker from the LCD. On battery, when you power on, the power, HDD and other lights up in the top cluster just continue to cycle and never turn off. The only thing I cannot try is the bios ship that is mentioned in Post #9 above. I have another Latitude, but it has a “B” chip. Can I install that chip and try it or will I toast it in doing so. Please post any replies. Hopefully solutions and not more problems.

  13. Clayton

    Hey Laptop Freak,

    So yesterday I decided to take out the old Latitude and try it. The video cable and memory had already been reseated from last time I tried fixing it. So I turn it on nothing happens, then i smash the keyboard and turn it on again and to my suprise it turned on. I connected to an external monitor, installed Win98se, microsoft office and Windows media player 9. So now it works but after a while a blue error screen will come up and it will freeze and it keeps coming up more often every time I use it. So last time I booted it up it said amount of memory changed or something around those lines. Then I turned it on again and it loaded windows. Is there a way I can stop this or am I screwed because I have “F” on my memory circuit board, or is there something I can buy to fix it.

    Thanks a bunch,

    Clayton

    I have Dell Latitude C640, when i press power button the Power and HDD LED both lights up then shut off in few seconds and nothing appears on the screen. Sometime i tried to press a button while pressing power button and it turns on. i was able to install windows xp and other applications. Then after several hour of using the laptop, i shut it down and go to sleep. then the following day i try to turn it on again, and i still experienced the same problem turns on and shut off in few seconds. please advice me what to do. thanks a lot in advance.

  15. Ramesh

    I have HP ZE4800 laptop. The laptop is not booting up. All the led lights up when i press the power button. Even i can hear the CD spinning and fan noise. The lights stays for 2-3 seconds and laptop loses power then it starts again. I tried draining the capacitor by holding the power button for 30 seconds, removing the battery and switching on the laptop with just AC power. But no luck. Any one know of any solution for this?

  16. Yehualaw

    I have a dell latitude laptop. I can power it on with a battery source which I got it from my friend’s same kind of laptop. When I put it on AC power, it doesn’t start up. I checked the adaptor with my friend’s laptop and the adaptor works excellent. Would it be a power supply problem? Please suggest me what I should do with this problem.

  17. I have a dell Inspiron 6400 Laptop, and facing the same problem with startup. When I power on the Laptop nothing happens the power ON indicator shows it got started but the screen remains blank. And the both the NUM and CAPS indicator blinks simultaneously. sometimes it automaticaly turns OFF with a click sound after 1 sec of pwer ON. Please help me.

  18. There is definitely something wrong with Dell’s power button engineering. I have an Inspiron, and had a Latitude before that with power button problems. On the Inspiron it started out with the NUM and CAPS lights lighting up in a weird way. Then the power button had to be pressed very firmly to work. Eventually the NUM etc lights stopped working entirely and the button really has to be crushed to work. Now the blasted thing won’t power up at all. By the way, on the Latitude, I noticed a connection between the power button and the keyboard, as someone else posted earlier – pressing on the keyboard helped the power button respond, but several keys eventually stopped working. Weird!!

    Somebody out there knows something – please post some help here!

  19. Hi.i have a HP pavillion dv6516tx laptop;just 1 month ago.I am also facing the same kind of issue.
    1.When i turn ON the power LED it turns on and turns off after 2 seconds.
    2.Tried using battery alone and AC adapter alone.still the same condition.
    3.Reseated the Ram modules also.Still the problem exists.
    4.Sometimes the laptop would turn ON and work smoothly and sometimes it would not start as described above.

    Want help….and also wanted to know why this problem occurs sometimes but not all times.

  20. hi suresh,

    It happens to me all the time. I have 2 ram dimms 256 (came with the laptop) and 512 (bought from micro center). The system was working fine with these two dimms for very long time. After i started having this problem of reboot cycle, i removed the 512 ram and the system is now working smoothly. i hope this helps.

  21. Well, I opened up the Inspiron and found the problem (or at least part of it). The button itself is part of an assembly that overlays a control board (circuit board) beneath. It was evident that the button had failed physically due to excessive force when pressing on it. The button interface on the control board also had physically broken components from the same cause.

    But why did it become difficult to begin with? That’s not clear, but there must have been some kind of fault in the control board, because it also controls the num/caps lock LEDs, the volume control buttons and the mic, all of which failed about the same time, and prior to the power button difficulty. It could be dust or something got under the button panel and contaminated the board.

    Anyway, I’m awaiting replacement parts for both. I’ll post again when the computer is back together.

  22. Wayne Zatarain

    If the cap lock LED blinks 10 times then everything shuts down or if you appear to be locking up in the middle of the boot process, try placing a small piece of rubber on top of each of your memory modules so that it depresses them slight when you close the memory card access cover. It has to be just thick enough to press the module down, not too thick. This works if you are getting this cap light blink problem during boot and a shut down. It must have to do with heat warping the memory cards over time and causing the middle of the card to lift.

  23. For the Dell Latitude CPI-R, try putting the battery module into the slot adjacent. Worked for me.

  24. Latituede CPI A user

    Wayne,
    I have a B bios and I cut a small piece of cardboard the size of both memory modules and duct taped the memory cover back on and it has worked perfect so far after weeks of the power button problem. Would replacing the memory chips accomplish the same?

  25. Wayne Zatarain

    I’m not sure if it does the same thing or not. On several other forums some have found the spacer to work others have found failed memory. In my own case I found a failed 512 stick of memory I replaced both sticks with 512MB and found I had to use a small runner spacer on my B DIMM slot for my Latitude to recognize the new stick in the B slot. If all is working for you currently I would leave it along, it sounds like you found the problem. This problem can be either failed memory or a problem with the DIMM slots.

  26. Richard

    There is a design flaw in the Inspiron 1150 and similars, that make the power LED go on, flash, and then off in a few seconds. That is caused by some chip on the main system board receiving too much mechanical pressure by a plate in the same board. the following is a “paste and cut” of the fix for this model:

    “…FIXING THE PROBLEM – you have nothing to loose if it’s not working and outside warranty

    a) Remove power and battery, harddisk and DVD drive, mem chips etc., make sure you are
    well earthed to prevent static.

    b) Remove all screws from the base and remove screen – start by unclipping blue power
    button strip with screen flat open and removing keyboard, unplug screen cable, take
    off screen, etc etc. You will need to undo the nuts on the vga port as well as all
    visible screws, plus 1 screw under keyboard.

    c) when case open, remove all the components and metal bits, graphics card etc. Just
    keep pots for all the screws so you know where they go back. – It really is not as
    daunting as it all sounds, you just need a clear table and a bit of care with the
    parts.

    d) now, you have full access to the motherboad. Under the mini pci bus connector, which
    is positioned under the case cover labelled ‘C’ there is a plack plasic sheet stuck
    to the motherboard to insulate. Peel this back to reveal the components. See the
    photo (thread sheet 42) on the link above which shows this clearly.

    e) the IC (chip) which will have been dislodged by the pressure is an LVC14A with 14 pins,
    surface mount. It has really small pins and you prob wont see any damage (but you might
    see the marks on the black plastic sheet where the cover was pressing on it. – see the
    photo in link above.

    f) With a very fine electronic soldering iron (with a pin point tip) touch each of the IC
    legs for 1 second to remelt the connections that have likely fractured by the pressure.
    It is not that difficult – just needs a very steady hand. do not add any solder,
    you may burn the board or join two pins together – they are v. fine !!!

    g) Put it back together – AND IT WILL BE FIXED

    h) ENJOY YOU NEW LAPTOP and the fact you just saved £400 – Remember to remove the C cover
    tabs to stop it happening again.

    hope this helps someone like it helped me – cheers to NILLION on the thread above as his
    picture proved the clincher for me finding my problem and subsequently fixing it.

    Good luck

    PS – this was written on my 5150 and it didnt crash once – even though I am leaning on it
    whilst typing !!…”

  27. Hi, my laptop is a dell inspiron. When I press the power button, the fan starts running, I have no picture on the monitor, the caps light blinks a few times, and then the computer turns off. I am fairly positive it isn’t a bad ac adaptor, and I’ve had it inspected by a computer repair place and they were pulling the hard drive and memory and several different things, and it was working for awhile, but it now quits again. Any ideas?

  28. Laptop Freak

    KR,
    Remove as many devices as you can (hard drive, DVD drive, battery, wireless card, etc…) and start the laptop from the AC adapter. If you still experience the same problem, most likely you have a faulty motherboard.

  29. I have a Dell XPS M170. This morning when I went to turn it on, I got a “Cannot determine Power Source” error. It was plugged into the a/c adapter.

    I finally unplugged that and booted it on battery power…however, it won’t charge the battery now.

    After it is booted, it will run off a/c, just not charge.

    So, really, as soon as I lose battery power, I won’t be able to turn on my computer anymore.

    Any suggestions?

    i work at the IT department at my college. we saw this issue today with a laptop that didnt turn on. the battery and the power lights turned on every 10 seconds but the computer never turned on. we replaced the system board twice and found out it was a faulty POWER ADAPTER!
    thanks for the advice, i felt like contributing our solution

  31. Hey.

    I have a Dell Latitude and i am having a problem getting the computer to come on. The LED lights will come on, but if the power adapter is not plugged in, they stay on and wont turn off. At all. I had to remove the battery to cut the power. None of the computer actually starts though. If the power adapter is plugged in, then the battery light comes on like it is charging. I press the power button, but it comes on for a second, then flashes and just goes back to the battery light. I have changed power adapters, and batterys and have tried booting without the battery in. Nothing seems to work. Any tips?

  32. Hey everyone,

    I had the problem where when you press the power button the lights would blink briefly and then the laptop would turn off. Tried a bunch of things with no luck, and thanks to topdoghockey I finally tried a new power adapter. Boom! Laptop started working normally again.

    I should know better – always check the cables first! Anyways, thanks topdoghockey =)

  33. Hello,

    I have a Compaq Presario C306 and my laptop will not stay on. I had an AC adapter that I had plugged into my laptop, and all of a sudden, while I was listening to some music, the power button, power indicator light and charge indicator light on my laptop started flickering (like when I light bulb is about to go out) and then my computer just shut off. The AC adapter no longer worked, so I went out and bought another one. I plugged that one in, turned on my laptop, and it brought up the Windows XP screen, and almost completely loaded my desktop as normal (fan working, hard drive working and all like normal) and then it did the flickering thing again and shut off. I thought that maybe the internal battery was just really drained, so I left the new AC adapter plugged in all night to see if it would charge. The next morning I tried it again and the lights flickered a little bit, but it didn’t come up. As soon as I unplugged the AC adapter, the computer went completely dead. At least when the AC adapter is plugged in, the charge light comes on like the laptop is charging. After I try to turn it on, it starts the flickering again. I removed the laptop battery and tried to boot up the computer with the AC adapter and that didn’t work, still the flickering. I did notice that the laptop battery had a little white corrosive powder on it, but that was easily just blown away. I really need the data off of my computer, so I’m hoping all is not lost. Help!

  34. Laptop Freak

    ramona,

    I really need the data off of my computer, so I’m hoping all is not lost.

    Here’s how you can transfer data from the laptop hard drive to another computer. I would try using external USB enclosure for notebook hard drives.

  35. Follow up on Inspiron 600m:

    I replaced the whole power button assembly (top panel and circuit board interface) – not difficult really – but it did not solve the problem with the button not reliably initiating a power-up from sleep or off condition.

    After reading Richard’s post above (Aug. 30), that really seems like what’s going on. Mechanical pressure on the keyboard etc. does play a role in this problem, and is often the only way that I can get the machine to power up. Thanks Richard!

    It will be some time before I can attempt that repair – I’ve since purchased a new HP dv2715nr notebook ($580), which I love – so it’s not as urgent for me now.

    BTW, on a separate topic, for transferring data from a HDD (which I had to do on the Inspiron) I used Drive Image XML. An awesome FREE program that copied a fully bootable exact image of the old laptop HDD onto a new one.

    I have a Dell B130 and I got a blue screen of death one day, something about a driver IRQ or something along those lines. I didn’t think nothing of it and powered the laptop off and it hasn’t been the same since. Now when I press the power button, the top three lights blink once and the power button stays on for about 3 seconds then goes off. The fan or cd drive don’t make any noise and there is nothing that comes up on the screen. I thought it was broke for sure so I set it aside for 2 months until one day I got bored and pressed the power button and the laptop started up and worked fine! After 2 days the laptop shut off and started with the problems again. I have gotten the laptop to start up 3 times since then but it will shut off after about a day of use. I made a video of my problem. http://youtube.com/watch?v=Wm8tPww9rKs
    Any help would be appreciated!!

    This is the closest problem I had and did all this person did to try and fix it.
    1.When i turn ON the power LED it turns on and turns off after 2 seconds.
    2.Tried using battery alone and AC adapter alone.still the same condition.
    3.Reseated the Ram modules also.Still the problem exists.
    4.Sometimes the laptop would turn ON and work smoothly and sometimes it would not start as described above.

  37. Laptop Freak

    Marshall,
    I think it’s bad motherboard. This problem is not related to RAM or hard drive as someone mentioned in comments to your youtube video.
    I don’t think it’s related to the CMOS battery either. The laptop should start even if the CMOS battery is missing.
    Most likely bad motherboard. If you decide to replace it yourself, you can use this manual.

  38. hi i have an HP pavilion N3410 windows 98 running win XP and it has an AMDK6 2 processor, and it was working fine up untill 2 days ago, when i took it apart to replace the nonworking fan, now the power light comes on along with the cd drive light which shortly goes off, and very faintly i can see the hard drive light flash/and or stay steady. i can also hear the new fan as well as the hard drive whirring, there is no monitor display as far as i can tell, then after 5 seconds or so, it just cuts off, what can i do? i dont want to spend bunches of money( no more than i have to) please help , Kotik

  39. I Have a similar problem with my Dell Latitude D610, I Have Reseated the video cable but the problem is still perssistent.

    Dell Inspiron B130 — battery doesn’t charge, computer starts up normally when it is plugged in (with or without battery), but suddenly shuts itself off after about 5 minutes or so (sometimes a little more time, sometimes a little less time). Then it won’t start up at all – no response to power button. I leave it sitting for a while – 20 minutes, say, and then, again, it starts up seemingly normally and then shuts itself off after five minutes or so.

  42. Dell Inspiron 6400 won’t boot up – only the power LED stays on after pressing it. All other LEDs go off. There is power in the DVD drive because i can open it up with the button. also the harddrive seems to be spinning.

    the screen stays blank and the harddrive activity LED also stays off.

    Anyone with any solutions.

  43. Chilena

    I have a Dell Latitude D600. It doesn’t seem to want to boot up. It was working fine for a couple of days. But the internet was being crazy and not loading certain things. So I restarted it and I haven’t been able to even get to the desktop since. I’ve tried running the PSI test, everything passes. No safe modes work either. It loads a bit on the Windows screen, then freezes, flashes the blue screen for half a second, then tries to restart again. Pressing down in the middle of the keyboard doesn’t seem to work either. Help me please.

    Could be heat related problem. It’s possible the laptop shuts down because of overheating. Can you hear the cooling fan working before the laptop shuts down? Maybe the fan is bad. Make sure the heat sink is clean and there is no dust inside. You can clean the heat sink with compressed air.

  45. Laptop Freak

    Myke,

    Dell Inspiron 6400 won’t boot up – only the power LED stays on after pressing it. All other LEDs go off. There is power in the DVD drive because i can open it up with the button. also the harddrive seems to be spinning.

    Could be memory problem. Try reconnecting the memory module, move it to another slot. Try replacing memory with another know good module.

  46. Laptop Freak

    Chilena,

    It loads a bit on the Windows screen, then freezes, flashes the blue screen for half a second, then tries to restart again.

    I would run memory and hard drive test first. You can test memory with Memtest86+ and hard drive with Hitachi’s DFT. I linked to both utilities in “Useful Links” on the right side.

  47. I think it is the ram memory, try reseat it or replace it, try only to run in one memory slot, it can be the one of the slots in systemboard that is broken?!

    good luck

  48. i have that problem i tride a new operating system that dident work i replaced the hard drive that dident work. but pressing down hard on the keybord and ont the back underneth the keybourd worked every time i also found tilting it worked a lot too.

  49. My Dell Latitude D410 laptop will not start AT ALL…

    I was working on some homework when all of a sudden the screen just froze. This is the first time that my laptop ever froze, so I just decided to turn it off and turn it back on again.

    However, when I tried to turn it back on, nothing happens. The screen doesn’t turn on, the fan doesn’t turn on. The only thing that happens is the LED lights turn on briefly and the CAPS LOCK light flashes ten times. After the 10th time, the laptop completely shuts down again.

    I tried turning it on with and with out the battery and I get the same result. I am really freaking out here…I’ve had this laptop close to 2 years with ZERO problems…can anyone HELP me!?!

    Thank you in advance for your help.

  50. motobaridi

    had a similar problem with my dell inspiron 3700. here’s how i solved it:
    opened up the laptop case, unplugged all cable connections, then plugged them back in. my dell is humming fine again…
    thanks guys for your pointers.

    I have a Dell Latitude D820 – working good for over a year. I turned it off before Jan 1 and when I turned it back on it would not boot. It would turn on, see the screen where the progress bar is, but it stops at the first part of the progress bar – a few times it has gotten past that point, but then Windows says there is an error and offers to boot into Safe mode, but booting into Safe mode or normal mode fails and it comes around to the BIOS and the POST progress bar it hangs again. I have not gotten it past the POST progress bar for weeks now.

    I have tested with a different HD that I know is working and no change.
    I have replaced memory – no change.

    What should be the next steps here?

    Could it be a BIOS version issue? (BIOS Version A07).

    Any help would be appreciated.

    Thanks.

    One more thing on my post above:
    I have tried booting with and without the battery on AC power and attached to a D-Port replicator – no difference.

    Just wanted to contribute since I found this thread helpful. Had a 600M on the bench for upgrade finished installing all the new software and and OS flawlessly. After four days of sitting on the bench running I turned it off. Today I go and grab it for the client and the exact problem as originally described here in the start of this thread. I had all the lights blinking more or less lit up really but you could still tell there was some slight blinking to it and she sounds like she was powering up, then boom totally dead. nothing. Check power power supply, HDD, external devices, memory * (I put a start there for a reason, we’ll get back to that) and battery. No success but HDD clears diag on the test bench and so does the memory and battery. Known working power adapter still yielded the same results. After reading this thread, specifically about the power button and having to press really hard I gave it a go. Sure enough she started to boot more than before but then the cap lock light blinked 3 times and she shut right down. This of course is the memory indicator and sure enough after re checking my modules I determined I had not properly reseated one of them. Closed her back up and mashed the the power key nice and hard and Voila, she’s back up and running. The power key is definitely jacked and I can tell it just by physical touch. The memory error I created myself in the process of trying to solve things. This power button design is very poor in my opinion, and I had to physically take apart the chassis in order to remove some debris and worn plastic in the actual mechanism.

    Nothing more than a mechanical failure are a result of poor engineering……..

    Hope this is helpful :)

    I have a similr problem with my HP pavillion laptop I have the laptop with the battery in plugged into the powerlead I press the on button the computer starts all lights come on and I can here the fan starts also but after 1 second the computer just turns off no display ever comes up at all some times if I leave the laptop plugged into the power for a while it might start but that is not a permanant soloution any ideas ?

  55. Dude, It’s your memory……

I was given a latitude c/640and it will now boot up at all with the harddrive, cd rom, and battery removed 19.95 volts out of ac adapter when you push the start button the middle light flashes 10 times and everything shuts down. With the battery in it does the same thing but the battery charge light comes back on and stays on for about 1 1/2 to 3 minutes and then go’s out any ideas? I have read throught some of the forums and find a lot of similaritys but nothing that makes sense to me. thanks for your time.

    Maybe memory failure? Have you tried reconnecting memory modules?
    If you have two RAM modules installed, try removing them one by one.

    Could be the AC adapter failure.
    If the battery has some charge, will it start from the battery power at all?

    Many things CAN cause this, but so many times, if there is no video and only a flashing led/light, The USB plug has been broken and the 5V line shorted and damaged the power supply.

  65. Hey,yea i got a problem like this too, still need an help with it, when i start up my Dell latitude D820, i get ONLY a blackscreen, not even the welcome screen, checked my ram, etc etc..
    tho, I DON’T Have the original AC Adapter for my laptop, but I use a HP one, doesn’t charge my battery, but for just a few days it was working fine.
    Now, i can’t start my laptop without the adapter, unless I get a new one, and charge my battery…
    I don’t actually think that is the problem.. so if anyone does, please Reply!

  66. I have a Dell Latitude D600. When I power it up, the 3 LEDs come on and it shuts down. If I press firmly down on it, close to the RAM it will power up to Windows, then freeze up. Battery is good (full charge), have tried taking the RAM out and putting back in. Nothing is permanently working. Any suggestions??

    Try removing memory modules one by one. Test the laptop with only one module (either one) installed.
    It’s possible one of the modules is going bad or one of the memory slots is bad.

    For those who have the dreaded Dell flashing cap problem
    The problem may be caused by heat damage to one or both of the RAM slots on the motherboard or defective slots. Reseating the RAM may work. You can try taking RAM stick B out and boot with just A and vice versa. You can also try different RAM in he slots as the RAM may be bad. Placing a small piece of rubber on the cover plate over RAM slot A, B or both seems to have worked for many. The rubber puts pressure on the RAM/slot so there is better contact. I had the same problem and the rubber fix worked for me. I found many solutions that worked on the link below

  69. Hi I press the power button on a dell latitude and it powers on and 5 sec later it cuts off.

    What could be my problem?

  70. Problem:
    D600 Blinking Caps Lock.

    Solution:
    Do not lock down the memory modules.

    Cause:
    In “some” D600s the plastic surrounding the bottom pins of the memory socket extends higher than it should. When locking the memory into place this causes the memory to rise away from the pins.

    Action:
    The chassis’ memory cover plate needs to have that black insulation on the inside. Place the memory firmly in the socket(s) but do not lock them in. Apply the plate and screw it in tight. The plate will hold the memory tight enough.

  71. i have a dell latitude d600, it boots and works fine, but when i plug it into the power supply the laptop just turns off, what could be the problem ?

    Hi all,
    Similar problem: DELL Latitude CPt C series fails to boot on A/C power as well as on battery power.

    When I try to switch on the laptop with only battery connected the battery indicator flashes amber once and does one flash every time I press the power button but nothing else. Blank and silent.

    As soon as I plug the charger in the battery indicator starts flashing rapidly (without pressing the power button) in amber and I can hear a clicking noize with every flash. The laptop does nothing, blank and silent.

    Tried with or without battery, another comtatible battery, another comtatible charger, no luck.

    It was running on mains with battery fully charged when it stopped working and shut down.

    Need advise. Thanks.
