Power - Toshiba Portege 7200CTe User Manual

Power

When the computer is not plugged into an AC adaptor, the battery pack is
the primary power source. However, your computer has a number of other
power resources, including intelligent power supply and Real Time Clock
battery. These resources are interrelated and any one could affect
apparent power problems. This section provides check lists for AC adaptor
and the battery pack. If you cannot resolve a problem after following them,
the cause could lie with another power resource. In such case, contact
your dealer.
