Getting Started 41 Charging the main battery 3 Connect the power cord/cable to a live electrical outlet. The AC power light on the indicator panel glows green. Never attempt to connect or disconnect a power plug with wet hands. Failure to follow this instruction could result in an electric shock, possibly resulting in serious injury. 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 green when the main battery is fully charged ❖ Is unlit when the main battery has discharged, the battery is not charging, or the AC adaptor is not plugged into the computer or AC outlet ❖ Flashes amber when the main battery charge is low and it is time to recharge the main battery or plug in the AC adaptor NOTE If the AC power light flashes amber during charging, either the main battery is malfunctioning, or it is not receiving correct input from the AC power supply. Disconnect the AC power cord/cable and remove the main battery pack. See "Changing the main battery" on page 100 for information on replacing the main battery. Charging the main battery Before using the battery to power the computer, you must charge the battery. To charge the battery, leave the computer plugged into an AC power source with the computer turned off until the battery light glows green. After that, the battery will be completely charged and ready to power the computer. NOTE Battery life and charge time may vary depending on the applications, power management settings, and features used.
