Overheating Power Down; Ac Power - Toshiba Portege M750 User Manual

Power
When the computer is not plugged into an AC power outlet, the battery
pack is the primary power source. However, your computer also has a
number of other power resources, including an intelligent power supply and
a Real Time Clock (RTC) battery, all of which are interrelated with any one
having the ability to produce apparent power problems.
This section provides checklists for AC power and the battery. If you cannot
resolve a problem after following them, the cause may lie with another
power related resource - in such an instance you should contact your
reseller, dealer or service provider.
