thinkpad battery problem?

Archived from groups: comp.sys.laptops (More info?)

A friend of ours has an ibm thinkpad. He leaves the battery in even
though he has the laptop plugged in to the ac. A few days ago the
computer got left on overnight (he usually turns it off after using it)
and in the morning the battery was dead, even though it was plugged in
to the ac. It took a long time to recharge the battery (after turning
the computer off). Now the computer is having alot of problems freezing
and programs not functioning right.

Any ideas what's wrong other than a virus, etc.? Could the battery have
caused this? There are still problems when the battery is removed.

Not sure of the model at the moment but could a surge go through the ac
transformer adapter? I'll have to cheick on the weather that night. He's
also got a cable modem - don't know if it could get through that way.
Could the battery going dead have drawn too much current trying to
recharge and heated up things too much?

Do you know if there are any programs that could scan for damage to the
cpu or mainboard?

Thanks..
