Power and Power-Up Modes

In such case, follow the steps below.

1.Fully discharge the battery by leaving it in the computer with the power on until the power automatically shuts off.

2.Plug in the AC adaptor.

3.Charge the battery until the Battery indicator glows green.

Repeat these steps two or three times until the battery recovers normal capacity.

Leaving the AC adaptor connected will shorten battery life. At least once a month, run the computer on battery power until the battery is fully discharged, then recharge the battery.

Monitoring battery capacity

Remaining battery power can be monitored by the TOSHIBA Power Management Utility. Refer to Utilities in Chapter 1, Introduction.

Wait for a moment after turning on the computer before trying to monitor the remaining operating time. The computer needs this time to check the battery’s remaining capacity.

With repeated discharges and recharges, the battery’s capacity will gradually decrease. Therefore, an often used, older battery will not operate for as long as a new battery even when both are fully charged.

Maximizing battery operating time

A battery’s usefulness depends on how long it can supply power on a single charge.

How long the charge lasts in a battery depends on:

■How you configure the computer (for example, whether you enable battery power saving options). The computer provides a battery save mode to conserve battery power. This mode has the following options:

■Display auto off

■HDD auto off

■System auto off

■LCD brightness

■How often and how long you use the hard disk, CD-ROM and the diskette drive.

■How much charge the battery contained to begin with.

■How you use optional devices, such as a PC Card, to which the battery supplies power.

■Enabling Resume mode conserves battery power if you are frequently turning the computer off and on.

■Where you store your programs and data.
