Battery types
The computer has three types of batteries:
◆ Battery packs – main and secondary (option)
◆ Real Time Clock (RTC) battery
Main battery
When the AC power cord is not connected, the computer’s main power source is a
removable lithium ion battery pack, also referred to in this manual as the main
battery. You can purchase additional battery packs for extended use of the com-
puter away from an AC power source.
CAUTION: The battery pack is a lithium ion battery, which can explode
if not properly replaced, used, handled or disposed of. Dispose of the
battery as required by local ordinances or regulations. Use only
batteries recommended by TOSHIBA as replacements.
The main battery recharges the RTC batteries. The main battery maintains the state
of the computer when you enable Resume.
CAUTION: When the computer is powered off in Resume mode, and the
AC adaptor in not connected, the main battery pack and optional
secondary battery pack supply power to maintain data and programs in
memory. If the battery pack(s) is completely discharged, Resume does not
function and the computer loses all data in memory.
The following message appears when you turn on the power:
WARNING: RESUME FAILURE.
PRESS ANY KEY TO CONTINUE.
