Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer...
It's not an overheating problem, the computer is not getting hot or anything related, I've already tried changing the AC adapter, booting only with AC and no battery, and also all of these suggestions:
Try changing the following setting in the bios setup, under the
'Advanced' tab Dynamic CPU Frequency:
Mode = Always Low (NOT DYNAMIC) My
laptop has been running on AC power
without a problem for 24hours,
including many restarts, and when I
went back to the original bios
setting, the problem returned almost
straight away.
EDIT
Other suggestions I found on the web
from here and here:
Set the power plan to high performance
Set the power plan to "Minimal Power
Management" (1 and 2 do conflict)
Start - Control Panel - Device
Manager -- Processor - disable one
of two processors - reboot normally
4.Do this: Only plug battery into laptop
Turn on the laptop and start Windows
normally Plug AC adapter into laptop,
the screen will freeze Leave the
laptop the way it is for 12-24 hours
After 12-24 hours, turn it off the
hard way Once it is turned off, turn
it back on. The laptop is working now.
I have no idea of what can it be...
