The computer will not start up.

To turn on the computer, press the power button. When the computer is turned on, the power light is
turned on.

If the computer and the power light are not turned on when you press the power button, adequate power
may not be available to the computer.

The suggestions below may help you determine the reason the computer will not start up:

If the computer is plugged into an AC outlet, verify that the AC outlet is providing adequate power

●

by plugging another electrical device into the outlet.

If the computer is running on battery power or is plugged into an external power source other than

●

an AC outlet, plug the computer into an AC outlet using the AC adapter. Make sure the power cord
and AC adapter connections are secure.

If the computer is running on battery power:

●

Remove the primary battery pack and travel battery pack (if applicable) and plug the computer

●

into an AC outlet using the AC adapter. If the computer starts up, one of the battery packs
may need to be replaced.

If the battery light on the front of the computer is blinking, the battery pack has reached a low-

●

battery condition, which may not allow the computer to start up. Plug the computer into an AC
outlet using the AC adapter to start the computer and allow the battery to charge.
