If an AC adapter is not connected to your computer, the computer’s power source is
its battery. If the computer does not turn on when a battery is installed, the battery’s
charge may be depleted. To troubleshoot this problem, make a copy of the Diagnos-
tics Checklist found in Chapter 5 and fill it out as you complete the following
procedure:
1. Turn off the computer and peripherals. Disconnect the peripherals from AC power.
2. Reseat each installed battery by first removing and then replacing the battery in
its compartment.
3. Press the power button. Does the computer turn on?
Allow one minute for the computer to initialize its components before checking
for signs of power.

operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, “Total Power Fail-
ure When Using the AC Adapter.”
