When fully charged it maintains this information for up to a
month when the computer is powered off.
The RTC battery may have become completely discharged
while your computer was shipped, resulting in the following
error message during startup:
BAD RTC BATTERY
BAD CHECKSUM (CMOS)
CHECK SYSTEM
To recharge the RTC battery, connect the computer and leave
it powered on for 24 hours.
The computer’s RTC battery is a Lithium battery and should be
replaced only by your dealer or by a Toshiba service
representative. The battery can explode if not properly
replaced, used, handled or disposed of. Dispose of the battery
as required by local ordinances or regulations.
It is seldom necessary to charge the RTC battery because it
charges while the computer is on. If the RTC battery is low, the
real-time clock and calendar may display the incorrect time
and date or stop working.
When Hibernation mode is enabled and the RTC battery is
completely discharged, a warning prompts you to reset the
real-time clock.
Monitoring battery power
The computer’s main battery light gives you an indication of
the main battery’s current charge:
❖
Green indicates the AC adapter has fully charged the
battery.
❖
Amber indicates the AC adapter is charging the battery.
