varies depending on usage. The 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 maximum capacity and will need to be replaced. 
This is normal for all batteries. To purchase a new battery 
pack, see your accessories information that shipped with your 
computer or visit the Toshiba Web site at 

To ensure that the battery maintains its maximum capacity, 
operate the computer on battery power at least once a month 
until the battery is fully discharged. Please see 

 for procedures. If the computer is 

continuously operated on AC power, either through an AC 
adapter or a docking station (if applicable to your system), for 
an extended period (more than a month) the battery may fail 
to retain a charge. This may shorten the life of the battery, and 
the battery light may not indicate a low-battery condition.

In addition, the computer has an internal real-time clock 
(RTC) battery. This is a nickel metal hydride (NiMH) battery. 
The RTC battery powers the RTC memory, which stores your 
system configuration settings and the current time and date 
for up to a month while the computer is turned off. 

If you spend a lot of time traveling and need to work for 
many hours without an AC power source, you may want to 
carry additional charged batteries with you. You can then 
replace a discharged battery and continue working.
