Troubleshooting checklist
Before turning on the system, make sure that:
■
The power cord is connected to the AC power-in connector and
an AC outlet.
■
The AC outlet is supplying power.
■
If a power strip is used it is turned on, setting the circuit breaker.
■
The voltage selection switch on the system power supply reflects
the proper voltage.
Verifying your configuration
If your system is not operating correctly, the BIOS may contain an invalid
configuration parameter. Enter the BIOS Setup utility and check your
configuration settings.
Troubleshooting guidelines
As you troubleshoot your system, keep the following guidelines in mind:
■
Never remove the chassis cover while the computer is turned on.
■
Do not attempt to open the monitor; it is extremely dangerous.
Even if the monitor’s power is disconnected, stored energy within
the monitor’s components can be dangerous.
■
If a peripheral, such as the keyboard, mouse, drive, or printer does
not appear to work, make sure that all connections are secure.
■
If an error message appears on the screen, write it down, word for
word. You may be asked about it when calling Gateway Client Care.
■
Only qualified personnel should open the system for maintenance.
■
If you feel you are qualified to maintain the system yourself, make
sure you are properly grounded before opening the system chassis.
See Chapter 3, Case Access, for more information on preventing
electrostatic damage to the system.
