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 will not turn on.

●The display does not turn on.

●The power light is off.

To test the AC adapter:

1.Remove the battery from the computer.

2.Connect the AC adapter to the computer, and then plug it into an AC outlet.

3.Turn on the computer.

If the power light turns on, the AC adapter is working properly.

Contact technical support for information on obtaining a replacement AC power adapter. Select Start > Help and Support > Get assistance.

Using battery power

When a charged battery is in the computer and the computer is not plugged into external power, the computer runs on battery power. When the computer is plugged into external AC power, the computer runs on AC power.

If the computer contains a charged battery and is running on external AC power supplied through the AC adapter, the computer switches to battery power if the AC adapter is disconnected from the computer.

NOTE: The display brightness is decreased to save battery life when you disconnect AC power. To increase display brightness, use the fn+f4 hotkey or reconnect the AC adapter.

You can keep a battery in the computer or in storage, depending on how you work. Keeping the battery in the computer whenever the computer is plugged into AC power charges the battery and also protects your work in case of a power outage. However, a battery in the computer slowly discharges when the computer is off and unplugged from external power.
