Sample Toshiba Power Saver Properties Dialog Box
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.
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.
