Be sure to follow the important tips given here to continue to get the most use and enjoyment out of your
computer. Failure to do so might lead to discomfort or injury, or cause your computer to fail.
When your computer is turned on or the battery is charging, the base, the
palm rest, and some other parts may become hot. The temperature they
reach depends on the amount of system activity and the level of charge in
the battery.
Extended contact with your body, even through clothing, could cause
discomfort or even a skin burn.
Avoid keeping your hands, your lap, or any other part of your body in
contact with a hot section of the computer for any extended time.
Periodically take hands from using the keyboard by lifting your hands from
the palm rest.
Protect yourself from the heat generated by the ac power adapter.
When the ac power adapter is connected to an electrical outlet and your
computer, it generates heat.
Extended contact with your body, even through clothing, may cause a skin
burn.
To avoid spills and the danger of electrical shock, keep liquids away from
your computer.
Never use it to warm your body.
Prevent your computer from getting wet.
To avoid spills and the danger of electrical shock, keep liquids away from
your computer.
Protect the cables from being damaged.
Applying strong force to cables may damage or break them.
Route communication lines, or the cables of an ac power adapter, a mouse, a
keyboard, a printer, or any other electronic device, so that they cannot be
walked on, tripped over, pinched by your computer or other objects, or in
any way subjected to treatment that could interfere with the operation of
your computer.
