When Hibernation mode is enabled and the RTC battery is completely discharged, a warning prompts you to reset the real-time clock. The computer can be used while the RTC battery is being charged, although the charging status of the RTC battery cannot be monitored. Monitoring main battery power The computer’s main battery light gives you an indication of the main battery’s current charge: . Glows amber while the main battery is being charged (AC adaptor connected). . Glows blue or green (depending on your model) when the main battery is fully charged. . Is unlit when the battery has discharged, the battery is not charging, or the AC adaptor is not plugged into the computer or AC outlet. NOTE Battery life and charge time may vary, depending upon power management settings, applications and features used. . Flashes amber when the main battery charge is low and it is time to recharge the main battery or plug in the AC adaptor. 106 Mobile Computing Monitoring main battery power If the AC power light flashes amber during charging, either a battery pack is malfunctioning, or it is not receiving correct input from the AC power supply. Disconnect the AC power cord/cable and remove the battery pack. See “Changing the main battery” on page 112 for information on replacing the main battery.

The computer needs this time to check the battery’s remaining capacity and perform its calculations. 1 Highlight the power icon 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. What to do when the main battery runs low When the main battery runs low you can: . Plug the computer into an ext...
