When you disconnect external AC power, the following events occur: ● The computer switches to battery power. ● The display brightness is automatically decreased to save battery life. To increase display brightness, press the f2 hotkey or reconnect the AC adapter. Connecting AC power WARNING! To reduce the risk of electric shock or damage to the equipment: Plug the power cord into an AC outlet that is easily accessible at all times. Disconnect power from the computer by unplugging the power cord from the AC outlet (not by unplugging the power cord from the computer). If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded (earthed) 3pin outlet. Do not disable the power cord grounding pin, for example, by attaching a 2-pin adapter. The grounding pin is an important safety feature. To connect the computer to external AC power: 1. Plug the adapter into the power connector (1) on the computer. 2. Plug the power cord into the adapter (2). 3. Plug the other end of the power cord into an AC outlet (3). Testing an AC adapter Test the AC adapter if the computer exhibits any of the following symptoms when it is connected to AC power: ● The computer does not turn on. ● The display does not turn on. ● The power light is off. 42 Chapter 6 Power management
