Looking things over
Sometimes, the simplest things can cause trouble. To avoid unnecessary
service calls, be sure you check over the basics before you call for support.
In any complex system, there is potential for a forgotten connection, a
forgotten switch or a loose connector. Before powering up the system,
perform the following checks:
•
Is the power cord connected to the system unit and an AC outlet?
•
Is the AC outlet supplying power?
•
If you are using a power strip, is it turned on? Is the circuit breaker
set?
•
Does the voltage selection switch on the system power supply
reflect the proper voltage?
Verifying the configuration
If the system is not operating correctly, the BIOS may contain an invalid
configuration parameter. Enter the BIOS Setup program and check the
configuration settings.
Troubleshooting guidelines
As you troubleshoot the system, keep the following guidelines in mind:
•
Never remove the system covers while the system is powered up.
•
Do not attempt to open the monitor, it is extremely dangerous.
Even if the monitor power is disconnected, stored energy within the
monitor components can cause a painful or harmful shock.
•
If a peripheral such as the keyboard, mouse, drive, or printer does
not appear to work, ensure that all connections are secure.
•
If the screen displays an error message, write it down,
word-for-word. You may be asked about it when calling Technical
Support.
•
Only qualified personnel should open the system for maintenance.
•
If you are qualified to maintain the system yourself, make certain
you are properly grounded before opening the chassis.
