HELP: Thinkpad A31 Critical Low Battery Error

[robdls14]

I have a Thinkpad A31 it was fully working one day and the next it won 't boot up. Here's the details of what's happening:

-- When the battery is connected and the power button is pressed nothing happens.

-- When the battery is disconnected and external power only the IBM boot screen will come up and then eventually this comes up 0190: Critical low-battery error

I have tried replacing the CMOS battery myself and no luck. I was told that someone has tried replacing the IBM laptop battery and that did not fix the problem. I would appreciate any ideas.

Thanks

Rob

I also have the same problem and I found quite few others online who had the same problem too. There was nowhere though a solution posted.
I hope somebody from this site can help us.

I'm guessing it's a bad motherboard. There isn't much else it could be.

Hi guys ! I have the same problem too. Someone has succeeded to fix this problem ? I was thinking about replacing the ac power jack ... This could be a solution if it's possible, I don't know. Someone have informations about replacing an ac power jack ?

Apologies for being the pessimist for the day, but I've seen this twice, not on my machines thankfully, and both times it has been a case of a bad motherboard.
