The battery is low. Check the Status Indicator Panel to determine the
presence and condition of the battery. See “Status
Indicator Panel” on page 16. Use a Power adapter
until the battery is charged.

auto/airline) has no power
from the AC outlet, airplane
seat jack, or the car’s cigarette

Suspend/Resume button. Check your power
management settings, or close your applications
and go to the Power Savings menu of the setup
utility to adjust the timeout values to better suit
your operation needs.
