Determining Remaining Battery Power - Toshiba M400-S4033 User Manual

Determining remaining battery power

NOTE
1 Click Start, Control Panel, Performance and
Maintenance, and then TOSHIBA Power Saver.
2 Click the TOSHIBA Power Saver icon.
The Power Saver Properties window appears.
The remaining battery charge is indicated on the left side
of the dialog box.
With repeated discharges and recharges, the battery's
capacity gradually decreases. A frequently used older
battery does not power the computer for as long as a new
battery, even when both are fully charged.
Monitoring main battery power
Wait at least 16 seconds after turning on the computer before
trying to monitor the remaining battery power. The computer
needs this time to check the battery's remaining capacity and
perform its calculations.
TECHNICAL NOTE: The computer drains the battery faster at
low temperatures. Check your remaining charge frequently if
you are working in temperatures below 50 degrees Fahrenheit.
The computer calculates the remaining battery charge based
on your current rate of power use and other factors such as the
age of the battery.
