Real Time Clock battery
The Real Time Clock (RTC) battery provides power for the internal real 
time clock and calendar function and also maintains the system 
configuration while the computer is turned off. If the RTC battery becomes 
completely discharged, the system will lose this information and the real 
time clock and calendar will stop working - in this instance the following 
message will be displayed when you turn on the power:
S
**** RTC battery is low or CMOS checksum is
inconsistent ****
Press [F1] key to set Date/Time.
You can change the Real Time Clock settings by turning the computer on 
while pressing the ESC key and then the F1 key when prompted. Please 
refer to Chapter 10, 
for further information.
The computer’s RTC battery is a Ni-MH 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.
The RTC battery does not charge while the computer is turned off even if 
the AC adaptor is attached.
