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.
The battery is a disposable item. When its operation becomes short even
when fully charged, replace it with a new one.
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.

TOSHIBA Notebook PC, model "Satellite A30".
