WARNING! DO NOT connect the AC power cord to an AC outlet
prior to connecting the DC plug to the Notebook PC. Doing so
may damage the AC-DC adapter.
IMPORTANT! Damage may occur if you use a different adapter
to power the Notebook PC or use the Notebook PC's adapter to
power other electrical devices. If there is smoke, burning scent,
or extreme heat coming from the AC-DC adapter, seek servicing.
Seek servicing if you suspect a faulty AC-DC adapter. You may
damage both your battery pack(s) and the Notebook PC with a
faulty AC-DC adapter.
This Notebook PC may come with either a two or three-prong
plug depending on territory. If a three-prong plug is provided,
you must use a grounded AC outlet or use a properly grounded
adapter to ensure safe operation of the Notebook PC.
WARNING! THE POWER ADAPTER MAY BECOME WARM TO HOT
WHEN IN USE. BE SURE NOT TO COVER THE ADAPTER AND KEEP
IT AWAY FROM YOUR BODY.
Unplug the power adapter or switch off the AC outlet to
minimize the power consumption when the Notebook PC is not
in use.
