General Precautions
Safety Use for TV Tuner
If you have to operate your PC during a thunderstorm and are connecting
the TV tuner to an outside antenna, you should operate your PC using AC
power mode. The AC adapter offers some protection against (but does not
entirely prevent) possible electric shock caused by lightning. For complete
protection, do not operate your PC during a thunderstorm.
Battery Life
Battery life may vary considerably depending on the model
purchased, configuration, applications, power management settings
and features utilized, as well as the natural performance variations
produced by the design of individual components. Published battery
life numbers are achieved on select models and configurations
tested by TOSHIBA at the time of publication. Recharge time varies
depending on usage. Battery may not charge while computer is
consuming full power. After going through many charge and
discharge cycles, the battery will lose its ability to perform at
maximum capacity and will need to be replaced. This is a normal
phenomenon for all batteries. To purchase a new battery pack, see
the accessories information that is shipped with your computer.
Graphics Processor Unit (“GPU”)
Graphics processor unit (“GPU”) performance may vary depending
on the model purchased, design configuration, applications, power
management settings and features utilized. GPU performance is
only optimized when operating in AC power mode and may
decrease considerably when operating in battery power mode.
