Safety guidelines
While troubleshooting your computer, follow these
safety guidelines:
First steps
If you have problems with your computer, try these
things first:
• Make sure that the power cord is connected to
your computer and an AC outlet and that the
AC outlet is supplying power.
• If you use a power strip or surge protector, make
sure that it is turned on.
• If a peripheral device (such as a keyboard or
mouse) does not work, make sure that all
connections are secure.
• Make sure that your hard drive is not full.
• If an error message appears on the screen, write
down the exact message. The message may help
Customer Care in diagnosing and fixing the
problem.
• If you added or removed peripheral devices,
review the installation procedures you
performed and make sure that you followed
each instruction.
• If an error occurs in a program, see the program’s
printed documentation or the online help.
Warning
Never remove your computer case cover while your computer
is turned on and while the modem cable, network cable, and power
cord are connected.
Warning
Make sure that you are correctly grounded before accessing
internal components.

To avoid bodily injury, do not attempt to troubleshoot your
computer problem if:
- Power cords or plugs are damaged
- Liquid has been spilled into your computer

Instead, unplug your computer and contact a qualified
computer technician.
