Battery types
The computer has two types of batteries:


Battery pack


Real Time Clock (RTC) battery
Battery pack
When the AC adaptor is not connected, the computer’s main power source
is a removable lithium ion battery pack, also referred to in this manual as
the battery. You can purchase additional battery packs for extended use of
the computer away from an AC power source.
Before you remove the battery pack, set the computer to Hibernation
mode or save your data and shut down the computer. Do not change the
battery pack while the AC adaptor is connected.
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.
Do not remove the battery pack while the computer is in Standby mode.
Data is stored in RAM, so if the computer loses power it will be lost. It is a
good idea to save your data before shutting down the computer in Standby
mode.
Real Time Clock battery
The Real Time Clock (RTC) battery provides power for the internal real
time clock and calendar. It also maintains the system configuration.
If the RTC battery becomes completely discharged, the system loses this
data and the real time clock and calendar stop working. The following
message appears when you turn on the power:
**** Bad RTC battery ****
**** Bad Check sum (CMOS) ****
Check system. Then press [F1] key.
The computer’s RTC battery is a nickel metal hydride (NiMH) 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.
