Removing the Computer Stand
CAUTION:
Your computer is heavy (it has an approximate minimum weight of 55 lbs) and can be difficult to
maneuver. Seek assistance before attempting to lift, move, or tilt it; this computer requires a two-man lift. Always
lift correctly to avoid injury; avoid bending over while lifting. See your Product Information Guide for other
important safety information.
CAUTION:
The computer stand should be installed at all times to ensure maximum system stability. Failure to
install the stand could result in the computer tipping over, potentially resulting in bodily injury or damage to
the computer.
1 Follow the procedures in "Before You Begin" in the User’s Guide.
2 Carefully, with the help of an assistant, tip the computer back at a very slight angle from the ground.
3 Pull the front of the computer stand down towards the ground, to release it from the front of the
computer.
4 Pull the computer stand toward the front of the computer until the stand is free.
Caring for Your Computer
To help maintain your computer, follow these suggestions:
• To avoid losing or corrupting data, never turn off your computer when the hard drive light is on.
• Schedule regular virus scans using virus software.
• Manage hard drive space by periodically deleting unnecessary files and defragmenting the drive.
• Back up files on a regular basis.
• Periodically clean your monitor screen, mouse, and keyboard (see your User’s Guide for more
information).
Solving Problems
Troubleshooting Tips
Perform the following checks when you troubleshoot your computer:
• If you added or removed a part before the problem started, review the installation procedures
and ensure that the part is correctly installed.
• If a peripheral device does not work, ensure that the device is properly connected.
• If an error message appears on the screen, write down the exact message. The message may help
technical support personnel diagnose and fix the problem(s).
• If an error message occurs in a program, see the program’s documentation.
• If the recommended action in the troubleshooting section is to see a section in your User’s Guide,
go to support.dell.com (on another computer if necessary) to access your User’s Guide.
