CHAPTER 6: TROUBLESHOOTING
Things to check before troubleshooting:
Ensure that the power cord is properly connected between your computer •
and a grounded, three-prong power outlet. Make sure that the power outlet is
working.
Make sure the UPS or power strip is turned on (if applicable).
•
If your peripheral devices (e.g. keyboard, mouse, printer, etc.) are not working, •
ensure that all connections are secure.
If any computer components were added or removed before the problem
•
began, check to see if you performed the installation procedures properly.
If an error message appears on the screen, please write down the exact error
•
message prior to calling Alienware Technical Support to aid in diagnosing
and resolving your issue.
If an error occurs in a specific program, refer to the program’s documentation.
•
Backup and General Maintenance
Always backup your important data on a regular basis and keep copies of your •
operating system and software safe. Do not forget to note the serial numbers
if you are storing them outside of their original cases - e.g., in a CD wallet.
Run maintenance programs as often as you can. You may schedule these
•
programs to run at times when you are not using your computer. You can use
those provided with your operating system, or buy more powerful, dedicated
programs to do so.
Write down your passwords and keep them safe (away from your computer). •
This is especially important if you choose to password-protect your system’s
BIOS and operating system.
Document vital settings such as network, dialup, mail and Internet settings.
•
When troubleshooting your computer, please remember the following safety
guidelines:
Before touching any of the computer’s internal components, touch an •
unpainted portion of the chassis. Doing so will safely discharge any static
electricity, which could damage your computer.
Turn off your computer and any connected peripherals.
•
Disconnect any peripherals from your computer. •
WARNING: Never attempt to open a monitor’s enclosure. Monitors contain
enough power, even when unplugged, to cause severe injury and even
death.
