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 included with your computer or visit the Toshiba Web 
site at 

. 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 

 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. In addition, your 
computer’s Power Saver utility can be used to select a power level 
setting for DVD playback. 

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
