Running the computer on battery power
Battery life may vary considerably from specifications depending
on product model, 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 the computer is consuming full power.
After a period of time, the battery will lose its ability to perform at
