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/data cord is connected to the
power module and that the power module is connected
to an AC power outlet.
• Make sure that the power outlet is supplying power.
• If you use a power strip or surge protector, make sure
that it is turned on.
• If a peripheral device 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 open your computer case while your computer is turned on and
while the modem cable, network cable, and power/data cable are connected.
