POWER AND

POWER-UP MODES

Battery pack

When the universal AC adaptor is not connected, the computer’s main power

source is a removable lithium-ion battery, also referred to in this manual as the

battery pack. 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

universal AC adaptor is connected.

CAUTIONS: 1. 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 recom-

mended by TOSHIBA as replacements.

2. 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 com-

puter is powered off in Standby mode, and the univer-

sal AC adaptor is not connected, the battery pack

supplies power to maintain data and program in

memory. If the battery pack is completely discharged,

Standby mode does not function and the computer

loses all data in memory.

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 Extending battery life in this chapter for procedures. If the

computer is continuously operated on AC power through a universal 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.

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:

1 2 ... 119 120 121 122 123 124 125 126 127 128 129 ... 258 259
