HP 4965AGN ユーザーズマニュアル

When the computer is turned on, the power light turns on. If the computer
and the power light are not turned on when you slide the power switch,
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.

Use only the AC adapter provided with this 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 that 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, until startup occurs:
◦

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.
