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

Extending battery life

in this chapter for

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.

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:

S

**** RTC battery is low or CMOS checksum is

inconsistent ****

Press [F1] key to set Date/Time.

Care and use of the battery pack

The battery pack is a vital component of portable computing. Taking proper

care of it will help ensure longer operating time on battery power as well as

a longer life for your battery pack. Follow the instructions in this section

carefully to ensure safe operation and maximum performance.

Safety precautions

Mishandling of batteries can cause death, serious injury or property

damage. Carefully observe the following advisories:
Danger: Indicates an imminently hazardous situation, which could result in

death or serious injury, if you do not follow instructions.
Warning: Indicates a potentially hazardous situation, which could result in

death or serious injury, if you do not follow instructions.

The computer’s RTC battery is a Ni-MH 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.

You can change the settings of the Real Timce Clock by pressing F1

key in response to the above prompt.

After configuring the time and date for the Real Time Clock battery, we

recommend that you turn the power status of your computer to "ON" so

that the Real Time Clock battery is charged.
