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 power outlet and 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 cord are connected.
