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 the following:

Plug in the power adapter,

Save your work and put the computer to sleep.

Then

Replace the empty battery with a charged one within two minutes.

IMPORTANT

Always save your work when you see a low-power message.

What you should know

When the first low-power message appears, the screen 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 and the screen

dims further.

The second message is followed by a third and final message indicating that

the computer is about to put itself to sleep or shut down. 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 charged battery.

If you can’t plug in the power adapter, the contents of RAM are retained in

sleep for about a day (as long as you don’t remove the battery).
