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. Connect the AC adaptor to the DC IN 15V jack of the computer, and the 
AC adaptor into power outlet.
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 in TOSHIBA Power Saver. 
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, which can be set in TOSHIBA Power Saver, to conserve battery 
power. This mode has the following options:
CPU Processing speed
Screen brightness
Cooling Method
System standby
System Hibernation
Monitor Power off
HDD Power off
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 at least 16 seconds 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 and to calculate the remaining 
operating time, based on the current power consumption rate and 
remaining battery capacity. The actual remaining operating time may 
differ slightly from the calculated time.
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. 
In this case, TOSHIBA Power Saver will indicate a 100% charge for 
both the old and new battery, but the displayed estimated time 
remaining will be shorter for the older battery.
