Question about IBM ThinkPad A31 Notebook

1 Answer

Works only with AC power plugged in; battery is recently replaced

Hi all, my A31's battery was replaced about a year ago. It's used mostly
while plugged in, but the battery was working fine. It shows a 93% charge.

The problem is that the laptop turns off the instant the power plug is pulled.

Anyone know how to fix that? Is there a certain power board that can be replaced? I replaced a power inverter for the LCD screen about 6 months ago.
It's very nice machine with a beautiful display. I'd like to keep it going.

Laptop not charging battery plugged in but


You can try taking out your battery and use only the charger (AC adapter only ) to see if the computer works. If your battery less laptop works fine that way, it is most likely that there is a problem with your battery.
You can also try testing your battery by substituting a battery that's functional from another laptop of the same model. If the substituting battery works fine then you may need to replace your battery :(

I recently used this company to purchase a new battery fro my laptop. I have HP laptop and my replacement battery only cost about $40. If you are looking for a low cost replacement, this might be helpful. Here is the link for the company I used.

Hope everything works out well for you!

I have an a31 i recently replaced the battery it works fine but when ever i put it for charging and disconnect it when it is done the battery meter says it is still connected so i cant get my real power...


Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.

1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.

Hope this will help...Thank you for using Fixya...

My Dell Inspiron 1525 is now around 4 years old and recently it has not been able to charge and only works when it is plugged in. Also when i start the laptop, it displays a message saying i need to...

As you say the system is 4 years old update the bios
your download link is here!
IMP. Be sure to plug in the battery and it should be charges above 10 % and the system should be connected to the mains power supply also ensure there will not be a power outage during the update process
this will resolve the issue 100 %
Dont forget to say thanks!

My IBM thinkpad a31 on works when i plug it in but i just bought a battery and it charges all the way but when it is unpluged and is on battery power it just turns off

How fast does it turn off? If it is within minutes, then the problem is the battery or the actual charging mechanism that switches from adapter to battery.

If the battery is fully charged and turns off immediately, get that particular part of the laptop checked out. It probably will need replacing.

Inspiron laptop Battery won't charge

Try taking out battery and plug in power. If it works, battery is faulty. If not,
Try taking out your hard disk plug in power, if it works, hard disk is faulty. If not,
Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

Ibm a31 0190 erroe

Error 0190 means you need to charge your battery. Either your battery is not charging properlty or your charger is not working anymore. If the computer works while plugged in and gives no error then it would be the battery that needs replacing. If the battery is a few years old then you may want to order a replacement. The Thinkpad A31 uses the ThinkPad Ultrabay 2000 Li-Ion Battery. You can purchase a replacement battery from this website:

If the laptop doesn't work while plugged in and you dont get any lights on the battery or power indicator on the front of the laptop then you may need a replacement. Depending on which region you are in you will need a different A/C adapter. You can find a list of different A/C adapters here.The A31 uses the 72 watt power adapters on this page:

I hope this helps.

I have major probs with both my laptops...

I think your problem is with the battery ac/power voltage.
Make sure of the right voltage for your Laptops is selected on the Ac/power device you are using.
In other simple words, the high voltage causes the laptop to cut off as yours, and the soloution is that you try adjusting the voltage into a lower voltage.
I hope this works!
