The battery in my laptop starts charging normally. Then after a few seconds the LED turns off and the battery stops charging.
I have a problem with a Toshiba laptop model M55-S325. When I plug the power cord while the laptop is turned on it starts to charge and the AC power LED turns on as well as the charging LED. Then after a few seconds the charging LED turns off and the battery stops charging but the AC power LED stills on. If I unplug the power cord and plug it again it happens again.
I also noticed that this happens only while I’m in Windows. If I charge my laptop turned off it charges normal. Also during the boot and loading of Windows the charging is normal. I checked the power jack and I don’t thing the problem is there. I move the power cord while connected to check for failures in both the jack and the cable and in both cases the laptop turn off and on but nothing happened, everything is the same. What do you think the problem might be? Please help.
Can the laptop run just on the battery power, when the AC adapter is unplugged?
The problem with your laptops is very similar to a battery charging problem with some Toshiba Satellite A105 laptops. Almost the same symptoms. In case of Satellite A105 the problem could be resolved by upgrading the BIOS version. I think it might work for your laptop too. Go to Toshiba tech support website and download the latest BIOS for your model. It looks like at this moment the latest version is v2.10
You mentioned that the charging problem occurs only in Windows. I think it might be somehow related to Toshiba Power Saver software. Try to reinstall the power saver.
If upgrading the BIOS version and reinstalling the power saver software will not help, you might have a hardware problem. In Satellite M55 the battery connects directly to the system board. So, it might be either the battery failure or the system board failure. The best way to test it is finding a spare battery and test the laptop with the new battery installed.

Hey, so it’s me again. Battery’s been changed…again, still the same problem. I did try wiggling the AC adapter’s jack but nothing doing. It recognizes the battery as being there, charges it for a split second and then switches to AC Power. What’s going on? Is it the motherboard? Or should I just invest in a new laptop? Where I’m at, we have constant power outages…could that be the problem? This thing is driving me up a wall, since my entire work is done on this machine.

i have a problem with my HP ZX 5000 laptop
when plugged into power, the battery it dont shows that its charging. but when is off it show is blinking then is going awy i buyit new AC Adpter and i buyit a new battery and i stel leave the sam problem it turned on overnight and turn it on in the morning, it goes fine for 10 t0 20 mint, then the Power and battery light on the front start blinking (maybe noting the battery is dying). then shuts down after certain time.
The main thing is that, if i remove the battery, the laptop doesnt turn on whatsoever…. the battery has to be there to turn on, otherwise there is no life.
I was told it might be the power regulator .and i thing is the problem is on the bord card so ever one els thing

Unfortunately, I’ve given in my battery for exchanging to another, clean one. So there’s no chance that it’s a faulty battery then, huh? If the problem persists after the new battery comes in, I’ll be back here…and try the solution offered.
Thanks for the quick response, though.

Madolyn,
Try this. Unplug the AC adapter and run the laptop on the battery power until it is completely discharged. After that try charging the battery again.
January 18th, 2008 at 11:01 pm
MP,
Can you make it charge if you wiggle the adapter power plug inside the jack? It’s possible that you have a problem with the power jack and it has to be replaced or resoldered.

Battery on Inspiron 1000 began charging several days ago, showed “96% remaining(charging)”.
It has never changed, why? What to do?
January 18th, 2008 at 8:36 am
Hi,
I have an HP Pavilion zv6500 and I’ve had it for about 2 years. I recently changed the battery, but after having plugged it onto what can only be deemed a faulty extension wire/plug, the battery doesn’t charge anymore.
The first time this happened, my battery was at 0%…I’d used it till the end, basically. When I plugged in the AC power to the laptop, the system tray icon showed the lightning bolt with the ‘charging’ text, and then switched to ‘on AC power’.
Now, when I plug in the AC power to the laptop, a light flashes briefly and then shuts off. Incidentally, when I do this with the laptop turned on, the icon in the system tray flashes a ‘charging’ for two seconds and then switches to ‘on AC power’ as mentioned above.
My question is: is it the battery, that I just replaced? Is it the circuitry which has suddenly fallen ill after the faulty plug I plugged it into? (Of course, I didn’t know it was faulty at the time) Or is it the AC adapter that can’t seem to provide power to both the battery and the laptop. Is it the motherboard? What is it?! I’m at my wit’s end, here. Any illumination on this would be a big help…
PS My battery’s a Li-Ion battery.

I’ve never seen a problem like this before. I guess it could be related to the RTC (CMOS) battery.
Check out the cooling fans and heat sink. Make sure the heat sink is not clogged with dust. It’s possible that your laptop shuts down without any reason because of overheating. Try cleaning the heat sink using canned air or air compressor.

I have a Toshiba Satellite Pro P100. For the last 3 weeks I have had the following problems.
1. Laptop will suddenly shutdown whilst still plugged into the AC power.
2. The time and date will slow down even whilst plugged in to the AC power.
Updated the BIOS. No difference. Reformatted the hard drive. No luck. Not sure if the problem is the RTC battery and a heating issue. The computer is only 2 years old.
Any ideas?

I have HP COMPAQ 6720 laptop. My doubt is…Is there any problems……turn on while charging and i have one question is that how to get maximum battery backup…..??????? i hope u will replay to me as soon…..My friend is told me about you……Your Very Genius…….

Dennis Douglas,
You are right. Here’s the rule for buying a new AC adapter for your laptop.
The output voltage must be exactly the same as it written on the laptop but the amperage could be the same or higher.
For example. If the laptop requires 19V-3.95A adapter, you can use 19V-4.74A adapter.
November 8th, 2007 at 5:02 pm
I have a Toshiba Satellite A70 laptop. Picked it up on ebay without an ac adaptor. I tried several adaptors rated 19v as required but shy on the required amperage. I was using a 450watt one. I noticed it would charge the battery ok when the laptop was off but once in windows it would not charge the battery. I read some threads above that pointed to anything from a bad motherboard, voltage regulator power supply or battery problem. Long story short, I bought the proper ac adaptor for it, 19v 6.3amps and voila, problem fixed. It now charges in windows. So if anyone has the same problem, that is how you fix it. Spend the money and get the right adaptor for your laptop. Hope this helps someone.
October 29th, 2007 at 4:12 pm
If the battery is a lithium-ion. You can usually fix it by wrapping it in a dish towel and throwing it in the freezer for 24 hours. remove it then let it heat back upto room temp. then see if it works.

Hey,
the battery of my toshiba satellite A60 won’t charge anymore. I openend it and it still has some power left so I think the cells or working fine. I think the electronics in the battery have locked it or something so it won’t charge anymore. I read somewhere that resetting the batterys memory could help. Since there is no reset button on the battery I wonder how this can be done. Would disconnecting the circuitbord inside the battery from the cells work? The circuit doesn’t get any power anymore so the memory should be resettet… or not?
March 6th, 2007 at 6:43 am
It is me again, sorry..
In the last half an hour I decided to flash the bios to A15, and see what it brings. Everything went ok, but the symptoms are still the same with the two batteries. after reading a few comments I have also tried to charge both ones while the machine on, the one is blinking still, the other is charging without any results. According to dell rapid orange (amber)blinking means “battery may be defective” -but than what the heck is the green blink on the end?
Is there anything like a battery redetection by dell? because the guy told me before he sent me the 2nd battery that by IBM laptops some battery manager program must be run, according to “redetect the battery” ’cause without this the laptop will think that it is still the dead one and won’t budge.
I am totally out of ideas what else I could try, please help me!
March 6th, 2007 at 6:11 am
Hi!
I have quite a nasty problem, and I need urgent help!
I have a DELL LATITUDE CPi A366XT. I have bought it with a dead battery. (If I had plugged it in AC, the charger led lit for 30secs than faded out). I sold the battery for a guy who renews them.
Lately I’ve found a used battery on the web titled “ok” with the same part nr. and bought it. When the stuff arrived to me I saw that it wasn’t the one that was photographed. I checked it at dell andfound that it is suitable for my laptop,but it didn’t power on. First I thought it was only depleted. I’ve plugged into AC, the charger led lit for almost an hour but, (small relief)than stopped but the machine didn’t power on from the battery afterwards, and the tester on the side of the battery didn’t lit either.
The guy appologised, and sent me another one, this time with the correct part number. The case by this is when I plug it into ac, the charger led lights green, than after 20 secs it blinks 3 times orange than once green, and this in a loop. I don’t know what to do..
I have bios version A10, and the latest is A15 -can a bios flash bring such help? (I’m terribly afraid that something goes wrong, and that the laptop won’t work at all after that)
Any Ideas? I need to do something fast, because the seller expects answers.

Hi,
I’m having a similar problem with my Toshiba Satellite Al05-S2201. The battery will not charge higher than 3%, although the power icon says it is charging. When I disconnect the mains power the laptop cuts out. I can’t start the laptop from the battery (obviously because it’s only at 3%). However, the laptop also cuts out intermitently while connected to the mains. I’ve tried updating the BIOS, I believe latest version for mine is V1.8, but this didn’t help!
March 2nd, 2007 at 8:41 pm
Hi there. I think my problem is somewhat similar to these, so here goes.
Laptop is eMachines M5312. Battery has always charged normally and I use the AC adapter every time I use the laptop, so the only time it is running off of batteries is when I’m moving it from one room to another or have closed it and it’s in sleep mode. Last week, I was asked about the battery by one of my students, so I disconnected it to show it to him, then reconnected it. Since then, Power Meter has been showing the battery at 0% and the charge light is constantly flashing. I disconnected the AC power to see if the battery was indeed at 0% and it ran for about 20 minutes before finally shutting off. I downloaded a utility called BatteryMon to see if I could get a sense of what was going on, and ran it after a complete shutdown and restart. The battery charged for about 10 minutes, though very slowly. It stopped at a capacity of 3774/969918 mWh and the charge light started flashing again.
Did I damage the battery somehow just by disconnecting and reconnecting it? The laptop was running at the time, so I’ve considered this possibility. From a bit of what I’ve read, it may be a problem with ACPI which is simply reporting incorrectly. That is, the battery is in fact charging, but Windows is not receiving that information properly, nor will any program I run because they rely on ACPI data also.
I really cannot believe my battery is bad all of a sudden, unless my actions caused it. Any advice you could offer would be greatly appreciated. Thank you.

i have the problem just like that. i have the Acer Extensa 2300 series, yesterday i had to replace my old batteries with the replacement one. this one have the 4400mAh. when i tried to charged it with my windiows xp SP2, it begin to charging until about a halh to an hour, it stop charging for no reason. that power bar said that it currently connect with the ac power, while the battery condition is still not fully charged. for example, when i try to charge, it about 14%, when it’s stop it about 20%.
the weird thing is when i shutdown my computer, and i pull the cable power out, then i plug it on again, it begin normally charging the battery. i know it even when my computer hasn’t booting up, it has the yellow sign of lamp at the battrey power. but still not for long the battery charging is stop, i know it from the flashing sign of the lamp at the battery power.
what can i do about that??? the battery has been try out in my friends laptop of the same series, and the result is fine. the battery is fully functionally.
what’s wrong with my computer???
February 26th, 2007 at 7:37 pm
Pete E.,
It sounds like a software related issue. Maybe the power management software is screwed?
1. Test the laptop with a new battery
2. Make sure the BIOS is up to date
3. Reinstall the operating system
4. If 1,2,3 will not help, it’s possible you have a problem with the charging circuit on the system board. I really don’t like this part from your description: “I actually hear a hiss sound, from the battery or very near it under the computer…”
Let me know how it goes with a new battery.
February 26th, 2007 at 7:21 pm
Greg,
It’s possible, try replacing the battery.
February 23rd, 2007 at 2:08 pm
My HP Pavilion N5470 battery, f2024a 11.1v 5400mAH died, so I just bought a new generic 11.1v 6600mAH off eBay. It has a 30 day warranty.
Battery came yesterday with partial charge, myPavilion N5470 said it was at 20%. I used laptop to run it down and then turned off laptop and charged it. It only charged up to 62% after a couple hours, and wouldn’t charge any higher. I unplugged charger and used laptop on battery for about 1-1/2 hours on wireless internet. When it ran down to 6% I plugged it back in, shut down laptop and left it charging overnight. This morning it was only at 62% again.
My charger is generic replacement for my N5470, but it puts out proper 19v 3.16a, and charged original battery to 100% just fine. The laptop says it requires 19v 3.16-3.30a.
Do you think this new 6600mAH battery is defective?
Thanks in advance

Laptop Freak
I have a charging problem on a Thinkpad R40 (with latest embed. controller and bios from lenovo, all the latest system drivers, win xp pro sp2) and have gotten some very specific behaviors from troubleshooting….
The battery will start charging from a discharged state (say 28%) if I just plug in the ac adapter. I am keeping the Battery Information screen up with status page – displays “Battery – Charging” current = 2.20A /voltage = raises as it charges/ wattage = 35.64W.
However, if I do anything else like click on start – control panel or basically use anything the charging bars all go dead and the status says “Battery – No Activity”. I can get charging going by unplugging and re plugging the adapter in – a couple secs and it pops back to charging with good indications on the Battery Information window. If there is any activity at all, it seems, (like going to a web page or opening an app.) I actually hear a hiss sound, from the battery or very near it under the computer and then 1-2 secs and the Battery Information window goes “Battery – No Activity” with the 3 meters dead. From there I can plug and unplug and reset until the next action. (The AC adapter or plug is not intermittent, I have wiggled and tested those thouroughly).
Another Symptom —
The problem goes away when the battery gets up to or greater than 80% or so.
At that point it charges normally and doesn’t go into “Battery – No Activity” on the Battery Information window. I also do not hear the hissing souds that is attached to activity like described above (also, I don’t hear that sound when the charging has shut down and the info window reads “Battery – No Activity”)
The problem seems load related – when at a lower % charge indicated , any load on battery while charging stops charging. At a higher % charge state (80%+) it seems the loads do not change or stop the charging. Battery problem??? Software? or Other hardware?
I have a reconditions IBM battery coming to see if that behaves differently. I would love to get your input, experience, or speculation however.
Thanks!!

Toto Sanderson,
Here are a few things to try. Update the BIOS, reinstall the operating system. If it doesn’t help, probably you have a problem with the motherboard.
I’ve published your question here, maybe somebody else has a better advice for you.

Hi Laptop Freak,
I’ve been longing for an answer for my Compaq NX9020 laptop’s battery problem.
Basically, last battery did not work so I bought a new one from HP store. I got it yesterday. It seemed fine. However, from this morning, problems came: while using AC adapter alone or battery alone, laptop works. However while using them together, laptop LED lights blinks and the power metre for battery drops down immediately to 0% critical level, whereas the battery LED indicator says it’s full. I tried to unplug the AC adaptor while it went down to 0%, then the power metre for the battery came back to normal 85%.
Any clues? Your help would be very much appreciated. Thanks!

Hello, I have a HP Pavilion ZV5000. I thought I had the common power jack detaching from the motherboard problem that seem to be widespread. I bought the Media cable that allow me to charge my laptop using the media slot. However, when I try to charge my laptop, the charge icon/light goes on and off intermittently. The same thing happens if I use the normal power jack. Thankyou
February 15th, 2007 at 11:22 pm
Nathan,
I think you have either a damaged power cord or a problem with the power jack on the motherboard. I think it’s a very common problem so I published your question and some suggestions here.
February 15th, 2007 at 2:52 pm
My dell inspiron 1100 stopped charging when I would plug in the charger. Both when it was on and off. I normally could get it to charge by moving the position of the cord as it was plugged into the back of the computer. It got progressively harder to make it charge until just recently it stopped charging at all. The charger itself, not the computer, started beeping when it was plugged into a power source and my computer is dead with no way to get any charge into the battery or run it with the AC power
February 9th, 2007 at 9:03 pm
I am having the same problem as Vinay. I am using a Thinkpad T23 and recently replaced the battery. I replaced it because i was not able to use my laptop without AC power and thought a new battery was in order. To my surprise when i installed the new battery it would still not charge. MY computer doesnt have any other problems other than this. What do you think it could be?
