My laptop will not boot with a new AC adapter
I have a Toshiba 320 CDT. The grandson lost the AC Adaptor. When I constructed another AC adaptor and plugged it in I get what appears to be a code? “53″ flashes on the AC LED. Nothing else happens, the battery doesn’t charge, its dead. But when I push in a bit on the on/off switch I will see a few flashes on the Battery LED. Wonder if someone can help me with this problem.
First of all, make sure that you use an AC adapter with correct voltage and amperage. The voltage should be exactly the same as required by the laptop specification; if 15 Volts adapter is required, you should find one that outputs exactly 15 Volts. The amperage should be as required by the specification or more; if 2A adapter is required you can use an adapter that outputs 2A or more. For example, if the laptop requires 15V-2A adapter you can use an adapter that outputs 15V-2A, 15V-3A, 15V-4A, etc… But if the laptop requires 15V-4A, you cannot use 15V-2A adapter. BTW, your Toshiba Satellite 320CDT requires 15V-2A AC adapter.

NO Power! HP ZE4400 I have found a blown IC on the motherboard. Trouble is I cannot read the numbers on the chip to ID that chip. It sits right next to a NDS9435A and is an 8 prong chip. The only number I see is 4800. Sits in slot PO15. I have a photo if that helps. This is a 10 cent repair if I can ID the chip.
Thanks a bunch.

I own a Dell Inspiron E1505. I usually have my laptop running on A/C power but when i want it to run off battery power and unplug the wire from the back of the computer(not the wall) the computer completely freezes. I’ve searched my computer for a way to convert the laptop to battery power before unpluging it from A/C power and found nothing. Basically I am trying to find a way where i can take my computer off A/C power and have it run off battery without having it freeze or have to shut it down completely and unplug it to have it run on battery power.

Davneet,
According to this table India uses 230V~50Hz power. Your AC adapter should handle it without any problem because it’s rated for 100-240V, 50-60Hz but the power plug is shaped differently. I would look for a universal power plug adapter. Just search on Google and you’ll find it.

Hi, I wasn’t sure what category to put this in, but I’m going to India for winter break and I was wondering what kind of converter I should get for my laptop. I have a Saellite M45-S355. Thank you.

Ken,
Check out these guys. I bought some parts form them recently and was very please with service.

When I remove the internal battery from my laptop and plug in the AC adpater the LEDs on the adapter and laptop light up, but the minute I try to power up both lights go out and the laptop’s dead.
When I replaced the original AC adapter I went through Toshiba. Not only was the sales/service person rude and snotty but they didn’t have any Toshiba adapters in stock — they’re the ones who sold me this lemon! I was desperate at the time (I rely on this laptop for work) but I later noticed that I could have saved $35 by ordering through another business. Is there an alternate place for Toshiba parts (other than eBay)?

Ken,
You are experiencing a problem with the AC adapter, so why do you want to replace the battery? I would recommend using an AC adapter especially designed for your laptop. You can find it by the Toshiba part numbers: K000006860, K000040120. Satellite P25-S526 requires an adapter that outputs 19V-6.3A. I’m scared of generic AC adapters.
Try this. Remove the laptop battery, plug in the AC adapter and start the laptop (without the battery installed). Can you turn it on, do you get any LED activity?

I have a Toshiba Satellite P25 S526. About 5 months ago I had to replace the AC adapter that came with it and chose an IGO Wall160. For the past several weeks the adapter has been acting strange. If I unplug it from the laptop the power would go out on the adapter. I would then have to unplug it from the wall, wait a good 30 seconds, the LED comes on (without being plugged in!) and the goes out, and I then replug it in. In the past few days it has really become testy, if I move the laptop very much the AC adapter goes out. Now if I try to plug it in with the laptop on or off the LEDs on the laptop and on the adapter go out and nothing charges. I assume it’s time I replaced the laptop’s internal battery (I’ve had the machine for two years) but even with the internal battery removed the AC adapter will not let me power up the laptop — it just goes out. It sure is frsutrating! Any ideas? Thanks.

Could you pleas ad more details? It’s not really clear what you mean by “managed power”. The laptop will not start with the AC adapter or what?

In the comment 18 you wrote:
Very strange problem, I’ve never seen something like this before. What if you remove the battery and run the laptop just from the AC adapter, do you still have the same issue? I’m just trying to find out if the adapter or battery is related to the problem. I would check if there is BIOS updated for your model and install it just in case. Let me know how it goes.
November 26th, 2006 at 3:34 pm
Thanks for the info guys. Although, I don’t think its the jack because it was beeping while it wasn’t directly plugged into the computer. I purchased another adaptor, but I wonder if there is anyway to salvage this one so if it happens again, I will know how to fix it. Thanks a bunch.

I have an HP Pavilion Notebook with power issues. It will only run on “managed power” that is used by the battery. When it is not on managed power it shuts down. Is this a power jack or ac adaptor? If it is a jack problem is their anyone out their who will fix it?
Your help is really appreciated.

Hi. I am reasonably computer-literate but this one has me stumped: I have a Compaq Presario V2670CA, and the wireless internet works perfectly, but only when the AC adapter is not plugged in. If the laptop is charging/running on AC power, it still finds the signal at excellent strength, but the internet is horribly slow or won’t work at all. As soon as I unplug the power, my browser finds the site it’s searching for.
How can the AC power cord have anything to do with internet speed?
November 25th, 2006 at 11:51 pm
Cassie,
I think that’s the only way to fix the problem.

Gregg,
I believe Pavilion ZD7000 has a power jack attached directly to the motherboard, and if the jack is faulty you’ll have to resolder or replace it. Here’s my post about replacing faulty power jacks in Toshiba laptops, I think the procedure will be very similar for all laptops with power jacks attached to the motherboard. Before you replace the jack, you’ll have to open up the laptop and remove the system board. Check out the Pavilion zd7000 notebook maintenance and service guide for step-by-step disassembly instructions. You can find a new power jack on ebay if you search for “zd7000 power jack”.

I have a dell inspiron 5160 and the ac adaptor suddenly stopped working, and would not charge my battery. When it is plugged into the wall, it emits a high pitched beeping sound. What is the cause of this, and is there anyway to fix it (without calling Dell)? I know it isn’t the motherboard or the battery because it beeps when it is not attachted to the computer as well. Do I just have to suck it up and buy a new adaptor? Thanks, Cassie

hi
I have an HP Pavillion ZD7000 that has a faulty power jack. I have the media cable so I can still power my laptop through the docking port but I would like to repair the ac power jack if possible. Does anyone have any info/photos etc on replacement of power jacks in this laptop? Any help much appreciated.
Thanks
Gregg

yes I have tried running without the battery and it still shuts down after a while.
I thank you for considering the problem none the less.

Matt,
I’m not really sure what’s going on with you laptop, it’s a very uncommon problem.
Could it be a bad AC adapter? What if you remove the battery and run the laptop only from AC power, will it shut down too?
I cannot figure out this part.

Lisa,
I covered this problem with Toshiba Satellite A70 laptops on my other site, check out this post: Toshiba Satellite M35X and Satellite A75 power jack and battery charge problem. This post will help you to fix the power jack related problem.
BUT before you jump in, check out this link http://www.a70m30xsettlement.com/notice.pdf. It looks like Toshiba extended warranty for Satellite M35X and Satellite A70/A75 laptops and you’ll be able to fix it under warranty. Call them for details. Good luck!

I have a Toshiba Satelite A70. It will not run with just the adapter (without the battery). With the battery in, it will not run on AC (just the battery). the battery will only charge when the ac plug is pressed to one side. Plugged in straight there are no lights on to show its plugged in. If I’m lucky, I can get the battery charged and turn on the computer for a little while. I had a tech look at it to see if the ac plug needed to be soldered onto the motherboard and he said it didn’t (but also didn’t know what to do with my computer). Any suggestions before I take it to an expensive dealer to have them monkey around with it?
THANK YOU FOR THIS WEBSITE!

Hi – I wonder if you can help me. I have an Hp nx6125 that was working fine but recently shut down whilst connected to the AC adapter. I tried to switch it back on and it lit up for about 2 seconds and then turned straight off again.I initially thought that the CPU had overheated or something and so I thought I would let it cool down and then a few hours later tried again. The laptop worked – Great! I thought, but when I pluged in the Ac adapter it immediately shut down. This only appears to happen when the laptop becomes warm and it is the correct adapter. I have checked that the fan is working and it appears to be working fine both when the Ac adapter is plugged in and unplugged. Do you have any ideas what this could be?
If you can help your wisdom would be very appreciated.
Thanks

No, I’m awaiting the arrival of the correct adapter from the retailer which I bought the laptop. I did remove the battery and try to restart it with just the battery, but it was dead (w/flashing green light).
Are you suggesting that when I receive the correct adapter there’s a chance it will restart?
November 13th, 2006 at 7:57 pm
Starr,
Do you have a correct AC adapter now? Have you tried removing the battery and starting the laptop just from the adapter (correct one) without battery installed.
November 11th, 2006 at 9:12 pm
Question:
I have just purchased a Toshiba M35X (S149), but the “incorrect” adapter was included, which had the “incorrect” polarity. I realized this after the laptop shutdown and the AC power light on the front of the laptop started flashing (green).
It will not power on, but the light is flashing. What kind of problem and costs am I facing?
Thanks in advance for any assistance you can provide.

Burak,
First of all you have to figure out if it’s software or hardware related problem. I’m not familiar with Asus M5N laptop, can you easily remove the hard drive?
Remove the hard drive and start the laptop from the AC adapter power. You will probably see Asus logo and then the laptop will try to find a boot device. Now unplug the AC adapter. Does the laptop switch to the battery power or it shuts down?
If the laptop successfully switches to the battery power when there is no hard drive (operating system), then most likely it’s just a software issue. Reinstall Windows XP again, but this time try it without Power4Gear software.
October 27th, 2006 at 7:14 am
Hi,
A couple of days ago I have installed a new Windows XP into my ASUS M5N laptop. The problem is when i unplug the power cable the computer restarts. However, it is supposed to switch to the battery mode.
I am using a program called “Power4 Gear” which controls the battery performance (when you are on battery mode you can either increase or decrease the battery life by using that program). I have been using Power4 Gear since I bought my laptop. So i don’t think the probem is because of Power4 Gear. The problem occured after I had formatted the laptop and installed a new Windows XP.
I would be very glad if you could help me with my problem.
Thanks in advance

Hey Stuart,
Sorry man but I think I cannot help you. I do not work on a component level and if a system board goes bad I just replace it.
I guess you can look up for a new motherboard on ebay. I just searched for “A60 motherboard” and found one for $114. Sounds like a good price.
Or, if you are experienced with soldering, you can wait for a cheap “not working” board and then transfer all needed components. I don’t think that I would go this route. You mentioned that two components looked to be toast, but there could be more bad components that look normal. I would probably go with a new board.

First off apologies for leaving this as a reply but I couldn’t find an ask question link…
I have a Satellite a60 that worked fine for a while but one day gave off a burning smell, then the ac adapter started making a squeek squeek noise… I switched it off thinking it was just overheating. It ran fine on battery until that ran out, then when I replugged in the power supply it continued to make this noise.
Quick check showed the AC input putting up very low resistance, opened it up using your top guide to find that the copper heat plate shown in fig 17 of the dismantling instruction (bottom left) was discoloured and the components beneath on close inspection (Q510 and Q504?) looked to be toast… Nightmare!
CAn you suggest if it possible to find these parts and if it is if fixing them is likely to solve the problem?
Many Thanks, Stuart

That helped, once I got the voltage correct I am getting a charge on the batterys and the flashing light has turned to steady green. Now my problem is getting the keyboard ribbon cable back in place properly, a lot of patience I guess. I should not have dismantled the unit.
