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.
