Toshiba A10 User Manual

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 

 for 

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

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: Depending on your system, the RTC battery may 
only charge while the computer is turned on.

Your computer ships with the power management options preset to 
a configuration that will provide the most stable operating 
environment and optimum system performance for both AC power 
and battery modes.

Changes to these settings may result in system performance or 
stability issues. Users who are not completely familiar with the power 
management component of the system should use the preset 
configuration. For assistance with setup changes, contact Toshiba’s 
Customer Support Center.
