Responding to low-power messages

When the battery runs low, the computer displays a series of low-power messages. The work time remaining after you see the first message varies depending on how you are using the computer. It’s a good idea to act promptly.

What you should do

When you see a low-power message, you should do one of the following:

mPlug in the power adapter.

mSave your work and put the computer to sleep.

What you should know

The first low-power message is a reminder that the battery will soon run out. When this message appears, the screen brightness dims automatically to save power.

If you continue to work without plugging in the power adapter or changing the battery, the computer displays a second low-power message.

The second message is followed by a third and final message indicating that the computer is about to put itself to sleep. Within a few seconds, the computer goes to sleep automatically to protect the contents of RAM. All activities are interrupted. It’s a good idea to save your work when you see the first two low-power messages to make sure you don’t lose information.

If you continue working until the computer goes to sleep automatically, you can wake it again as soon as you plug in the power adapter or replace the battery with a fully charged battery.

If you can’t plug in the power adapter, the contents of RAM are retained in sleep for about a day. If you recharge or change the battery within a day, you should be able to wake the computer and resume work where you left off.

IMPORTANT Recharge a depleted battery as soon as possible. Leaving a depleted battery in the computer for more than several months, or in a hot location (such as the trunk of a car) for longer than two weeks, may damage the battery so that it can’t be recharged. If this happens, you need to replace the battery.
