Displaying Battery Status to Users

Portable computers use a battery as a direct power source while disconnected from external power or as a backup power source while connected to external power.

When battery power is too low for the computer to function, the computer puts itself to sleep to conserve energy. When a user reconnects the computer to a functional power source (for example, by inserting a fresh battery or connecting a power adapter), the user can wake the computer and begin working again.
