Using Your MacBook Pro

Charging a Battery

When the power adapter is connected to your computer, the battery recharges

whether the computer is off, on, or in sleep. However, the battery recharges more

quickly if the computer is off or in sleep. When the MacBook Pro is on, you can monitor

the battery charge level using the Battery status icon in the menu bar.

The battery charge level displayed is based on the amount of power left in the battery

with the applications, peripheral devices, and system settings (display brightness,

Energy Saver settings, and so on) you are currently using. To make more battery power

available, close applications and disconnect peripheral devices not in use, and adjust

your Energy Saver settings (see the next section).

Understanding Battery Conservation Tips

The amount of work time your MacBook Pro battery can provide before you need to

recharge depends on the applications and peripheral devices you’re currently using

and the steps you take to conserve power while you work.
