Mobile Computing 89 Monitoring battery power HINT: Be careful not to confuse the battery light ( ), the power light ( ), and the power button light. When the power light or power button light flashes amber, it indicates that the system is suspended (using the Windows® operating system Sleep command). System indicator lights AC power light/Battery light ON/OFF light Wireless indicator light (Sample Illustration) Power and battery light locations 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 102 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.
