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:
m
Plug in the power adapter.
or
m
Save your work, put the computer to sleep, remove the depleted battery, and replace
it with a charged battery within two minutes of removing the depleted one.
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.
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
depleted battery with a charged battery.
If you can’t plug in the power adapter or replace the battery, the contents
of RAM are retained in sleep for about 8 hours (as long as you don’t remove
the battery).
