Mobile Computing Monitoring battery power 101 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 113 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. 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.
