Running the computer on battery power
Battery Notice
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 
maximum capacity and will need to be replaced. This is normal for 
all batteries. To purchase a new battery pack, see the accessories 
information that shipped with your computer or visit the Toshiba 
Web site at 
accessories.toshiba.com
. Use only batteries designed to 
work with your Toshiba notebook computer.
To ensure that the battery maintains its maximum capacity, operate 
the computer on battery power at least once a month. The Lithium-
Ion battery has no memory effect so it is not necessary to let the 
battery fully discharge each time. However, for better accuracy of 
the battery meter, it is helpful to fully discharge the battery 
periodically. Please see 
procedures. If the computer is continuously operated on AC power, 
either through an AC adaptor or a port replicator (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 may cause the battery meter to be inaccurate.
For optimum DVD performance, it is recommended that you play 
DVDs while running the computer on AC power. For more 
information about Windows

 power plans, see 
The computer also has an internal real-time-clock (RTC) battery.
The RTC battery powers the RTC memory that stores your system 
configuration settings and the current time and date information. It 
maintains this information for up to a month while the computer is 
turned off.
TECHNICAL NOTE: The RTC battery does not charge while the 
computer is turned off, even when AC power is attached.
The RTC battery charges only while the computer is powered on.
NOTE
