Charging the RTC battery

Your computer has an internal real-time clock (RTC) battery.
The RTC battery powers the System Time Clock and BIOS
memory used to store your computer's configuration settings.
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
NOTE
If the RTC battery is low, the real-time clock and calendar
may display the incorrect time and date, or stop working.
HINT: Once the battery is fully charged, Toshiba recommends
that you operate your computer on battery power until the
battery discharges completely. Doing this extends battery life
and helps ensure accurate monitoring of battery capacity.
The above error message may vary by computer model.
The RTC battery does not charge while the computer is turned
off even when the AC adapter is charging the computer. The
RTC battery charges when the computer is powered on.
