2Nd Battery Pack (Option); High Capacity Battery Pack; Real Time Clock (Rtc) Battery - Toshiba TECRA M3 User Manual

Power and Power-Up Modes
To ensure that the battery pack maintains its maximum capacity, operate
the computer on battery power at least once a month until the battery pack
is fully discharged. Refer to
procedures. If the computer is continuously operated on AC power through
an AC adaptor for an extended period, more than a month, the battery may
fail to retain a charge. It may not function efficiently over the expected life of
the battery and the Battery indicator may not indicate a low-battery
condition.

2nd battery pack (option)

An optional 2nd battery pack can be installed in the Slim Select Bay to
increase your battery operating time. Note the caution on Standby mode in
the previous section
The 2nd 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.

High capacity battery pack

A High capacity battery pack is installable instead of a main battery pack.
The connection method of High capacity battery pack is the same as that of
main battery pack.
■
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. When the computer is powered off in Standby mode, and the AC
adaptor is not connected, the main battery pack and optional 2nd
battery pack supply power to maintain data and program in memory. If
the battery pack(s) is completely discharged, Standby mode does not
function and the computer loses all data in memory.
■
Do not have only High capacity battery pack, when having connected
High capacity battery pack with the computer.
