Safety guidelines
While troubleshooting your computer, follow these safety guidelines:
■
Never remove your computer case cover while your computer is turned
on and while the modem cable and the power cord are connected.
■
Do not attempt to open the monitor case. To do so is extremely dangerous.
Even if the power is disconnected, energy stored in the monitor
components can be dangerous. Also, opening the monitor voids the
warranty.
■
Make sure that you are correctly grounded before opening your computer
case. For more information about preventing damage from static electricity,
see “Preventing static electricity discharge” on page 221.
First steps
Try these things first before going to the following sections:
■
Make sure that the power cable is connected to your computer and an
AC outlet and that the AC outlet is supplying power.
■
If you use a power strip, make sure that it is turned on.
■
If a peripheral device (such as the keyboard or mouse) does not work, make
sure that all connections are secure.
■
If you added or removed computer components before the problem started,
review the procedures you performed and make sure that you followed
each instruction.
■
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 Gateway Technical Support in diagnosing and fixing
the problem.
Warning Do not try to troubleshoot your problem if power cords or
plugs are damaged, if your computer was dropped, or if
the case was damaged. Instead, unplug your computer
and contact a qualified computer technician.
