Determining remaining battery power

NOTE Wait a few moments 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.

Move the pointer over the power icon in the notification area, see “Finding your way around the desktop” on page 132 for more information on the notification area. A pop-up message displays the remaining battery power as a percentage.

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.
