Some more time ago i had such a problem with a T20. It was a BIOS
problem. When the machine went to hot, it did not start the fan
properly (or any other cooling method) and suspended instead. That
would perhaps match the fact that it only happenes if connected to AC
power. The default Speedstep setting for AC power is maximum.

A newer BIOS helped me.

BTW: That problem did only occur with some users that stressed the
system. There were no problems when you were just reading mails.
