Thinkpad A30 thinks it's running on battery

2013-09-05, 4:01 AM

The other day I turned on my computer (after it had been off for about a week) and it would not boot up--I received a "critical low battery" error. The thing is, caccu.nl ,there was no battery in the machine. I popped in a long-expired battery to see what would happen and the computer would not even turn on.

I have ruled out the A/C adapter--I have another laptop of the same model which boots up just fine with either adapter, but this one will not boot with either.

I finally got the machine to boot up by popping in the battery at a strategic moment just before the error appears. It works fine as long as I leave it running, but Windows thinks that it is running from the battery ("Current Power Source: Batteries - Total Battery Power Remaining: Unknown") and the computer dies instantly if I remove the battery.

I have tried uninstalling and reinstalling the battery in Device Manager to no avail. Is there anything else I can do, or do I need to make the backup laptop my primary?

Welcome to the forum!

 

Sounds to me like your A30 has developed a motherboard problem.

 

Try the old trick:

 

Remove the battery, unplug the power adapter, hard and media drives.

 

Press the "power" button ten times in a row holding it down for ten seconds each time and thirty seconds the last time around.

 

Plug the adapter - but nothing else - back in and try to power on.

 

Let us know how it goes.

 

Good luck.

Cheers,

George
