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.
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. For more information about preventing damage from static
