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.
Monitoring battery capacity
Remaining battery power can be monitored by the TOSHIBA Power Saver
utility. Refer to Utilities in Chapter 1, Introduction.
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.
■ 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.
