As needed
Backing up your data
Keeping the computer free of dust, dirt, and heat
Keeping your computer system free of dust, dirt, and heat will prolong its life. Dust, pet hair, and other
particles can build up, creating a blanket effect; as a result, components can overheat, or, in the case of the
keyboard and mouse, not work smoothly and effectively. Check your system once a month for visible signs of
dust and debris, and clean it about once every three months. Visit www.hp.com/support for additional
cleaning instructions.

In time, your system might still get bogged down, depending on the computer
usage. Use System Recovery to wipe your Windows operating system installation
clean, restoring it to the original configuration when you first started your system.
Make a backup of important data files before proceeding with a
System Recovery. See System Recovery on page 19 for further details.
Use CD or DVD recording software that is installed on your computer to create (or
"burn") backup discs of important information, including personal files, e-mail
messages, and Web site bookmarks. You can also move data to an external hard
disk drive.
Air vents keep the computer and monitor cool. Keep these vents clean by using
a small, battery-powered vacuum cleaner. (A battery-powered vacuum cleaner
eliminates the risk of electric shock.)
1.
Vacuum the vents on the computer case and the monitor case.
2. Remove any debris that has accumulated in and around the computer
connectors (for example, the Ethernet and USB connectors).
Follow these steps to clean the computer and monitor:
1. Unplug the power to the computer and the monitor.
2. To clean the monitor screen, use a clean, dry cloth. Do not use water
on the monitor screen. For more thorough cleaning, use a clean cloth
and antistatic screen cleaner.
3. Use a clean, dry cloth to dust the computer case and the monitor case.
NOTE:
To remove sticker residue or a spill on the computer or monitor
case, use isopropyl (rubbing) alcohol and a lint-free cloth.
