Apple 145B manual Responding to low-power messages, What you should do, What you should know

The Battery desk accessory appears.

The line of rectangles is the battery gauge. Black rectangles indicate the charge level. You can see the level decrease while the battery is in use, and increase while the battery is recharging in the computer.

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 a series of low-power messages. The work time remaining after you see the first message will vary 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, do either of the following:

mPlug in the power adapter, or

mSave your work and put the computer to sleep.

What you should know

The first low-power message indicates that it’s time to recharge the battery. Right after this message appears, the screen brightness dims automatically to save power.

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