Troubleshooting
Quick troubleshooting
The computer is unable to start up
To turn on the computer, press the power button. When the
computer is turned on, the power light turns 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 following suggestions may help you determine why the
computer will not start up:
If the computer is plugged into an AC outlet, be sure that the
AC outlet is providing adequate power by plugging another
electrical device into the outlet.
If the power light on the front of the computer is blinking
rapidly, replace the AC adapter with one having a higher
power rating, and then plug the adapter into an AC outlet.
Use only the AC adapter provided with the computer or
one approved for this computer.
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. Be sure the
power cord and AC adapter connections are secure.
If the computer is running on battery power, try the following
procedures in the sequence provided:
If the battery light on the front of the computer is blinking,
the battery has reached a low battery level, which may not
allow the computer to start up. Plug the computer into an
AC outlet using the AC adapter, start the computer, and
allow the battery to charge.
Remove the primary battery and optional accessory
battery (if applicable) and plug the computer into an AC
outlet using the AC adapter. If you can turn the computer
on, one of the batteries may need to be replaced.
