Apple Duo 270C Responding to low-power messages, What you should do, What you should know, Lever

When you click the lever to the right of the battery gauge, a Sleep button appears.

Lever

You may sometimes find it convenient to put the computer to sleep by clicking this button, instead of choosing the Sleep command.

Responding to low-power messages

When the battery charge drops to about 15%, the computer displays three messages telling you that your computer is running on low battery power. You have about 10–30 minutes of work time remaining after you see the first message, so you have time to finish what you’re doing before recharging.

What you should do

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

nPlug in the power adapter, or

nSave 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. Right after 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.
