Displaying Battery Status for Users
Portable computers use a battery as either a direct or backup power source when not
connected to a power adapter. When battery power is too low to function, the
computer will put itself to sleep to conserve energy. When a user reconnects the
computer to a direct power source (such as by inserting a fresh battery or connecting a
power adapter), they can wake the computer and begin working again.
Users should be encouraged to monitor battery status when roaming free and use a
power adapter when possible to maintain a fully charged battery.
