Strange behavior from an old Acer Aspire 3000 laptop

We have an old Acer Aspire 3003 laptop that has been relegated to Skype duty. But recently the integrated mouse and keyboard would hardly respond at the login screen, as if something was consuming all the CPU. Starting Windows XP in safe mode fixed the problem so I proceded to wipe the hard drive and give it a fresh reinstall.

But the same problem arose during installation and again once Windows was installed.  After some more Googling, I came across several threads which suggested removing the battery (which hardly holds a charge anymore) and running the laptop only on AC power.  Lo and behold, that fixed the problem instantly.

Some theories I've heard is that battery circuitry overheats the south bridge chip on the motherboard for some reason, but I've not investigated further.

Weird.

Note: After further research, people suggest that simply disabling the "Microsoft ACPI compliant battery" in the Device Manager will be enough. If I get time, I might try it.
