Maintaining Your Computer

Caring for your computer

    Here are ways to extend the life of your system:

Be careful not to bump or drop your computer, and do not put any objects on top of it. The case, although strong, is not made to support extra weight.
When transporting your computer, we recommend that you put it in the original packaging materials.
Keep diskettes and your computer away from magnetic fields. Magnetic fields can erase data on both diskettes and hard drives.
Never turn off your computer when the hard drive light is on because data on the hard drive could be lost or corrupted.
Avoid subjecting your computer to extreme temperature changes. The case can become very brittle and easy to break in cold temperatures and can melt or warp in high temperatures. Damage due to either extreme is not covered by your warranty. As a general rule, your computer is safest at temperatures that are comfortable for you.
Keep all liquids away from your computer. Almost any liquid can result in extremely expensive repairs that are not covered under your warranty.
Avoid dusty or dirty work environments. Dust and dirt can clog the internal mechanisms.
Set up a regular maintenance schedule according to the table below to keep your computer running at its best.

Protecting your computer from viruses

    A virus is a program that attaches itself to a file on a computer, then spreads from one computer to another. Viruses can damage data or cause your computer to malfunction. Some viruses go undetected for a period of time, because they are activated on a certain date.

    Protect your computer from a virus by:

Using your Norton ® AntiVirus program to check files and programs that are on diskettes, attached to e-mail messages, or downloaded from the Internet.
Checking all programs for viruses before installing them.
Disabling macros on suspicious Microsoft Word and Excel files. These programs will warn you if a document that you are opening contains a macro that might have a virus.

Scanning the hard drive for errors

    The ScanDisk program examines the hard drive for surface errors and file and folder problems. ScanDisk corrects these problems so that Windows and other programs run efficiently.

    If you use your computer several hours every day, you probably want to run ScanDisk once a week. On the other hand, if you use your computer less frequently, once a month may be adequate. Also use ScanDisk if you encounter hard drive problems.

Defragmenting the hard drive

    When working with files, sometimes Windows divides the file information into pieces and stores them in different places on the hard drive. This is called fragmentation , and it is normal. In order for the computer to use a file, Windows must search for the pieces of the file and put them back together. This process slows the hard drive performance.

    The Disk Defragmenter program organizes the data on the drive so that each file is stored as one unit rather than multiple pieces scattered across different areas of the drive. Defragmenting the information stored on the drive can improve hard drive performance.

    While the Disk Defragmenter program is running, do not use your keyboard or mouse because using them may stop and restart the defragmenting process. Also, if you are connected to a network, log off before starting Disk Defragmenter. Network communication may stop the defragmentation process and cause it to start over.

    1. Click Defragment Now.

    2. If Disk Defragmenter does not start automatically, click Start or Defragment .
      Disk Defragmenter shows its progress on the screen. When finished, Disk Defragmenter asks if you want to quit the program.
    1. If you want to defragment another drive, click No then follow the on-screen instructions.

Backing up files

    Backing up files and removing them from the hard drive frees space for new files on the hard drive. It also protects you from losing important information if the hard drive fails or you accidentally delete files.

    You should back up your files regularly to diskettes or a writable CD, if you have a CD-R or CD-RW drive. Use diskettes or writable CDs to do partial backups of selected files or folders. Use a backup device such as a CD-R, CD-RW, or Zip drive, or other high - capacity backup device to do a complete hard drive backup. If you do not have a high-capacity backup device and you want to do so you can contact us and we can take care of this for you.

Cleaning your computer

    Keeping your computer clean and the vents free from dust helps keep your system performing at its best. You may want to gather these items and put together a computer cleaning kit:

A soft cloth
Window cleaner (not for use on LCD panels)
An aerosol can of air that has a narrow, straw-like extension
Isopropyl alcohol
Cotton swabs
A CD/DVD drive cleaning kit

Cleaning the exterior

 
 
Warning

When you shut down your computer, the power turns off, but some electrical current still flows through the computer. To avoid exposure to dangerous electrical voltages and moving parts, turn off your computer, then unplug the power and modem cords before cleaning the exterior. Please contact us so we can take care of this for you.

 

    Always turn off the computer and other peripherals before cleaning any components.

    Use a damp, lint-free cloth to clean the computer and other parts of your system. Do not use abrasive or solvent cleaners because they can damage the finish on your components.

    Your computer is cooled by air drawn in through the vents on the case, so keep the vents free of dust. With the computer turned off and unplugged, brush the dust away from the vents with a damp cloth. Be careful not to drip any water into the vents. Do not attempt to clean dust from the inside the computer. Back to the top of the screen.

Cleaning the keyboard

    You should clean the keyboard occasionally to free it of dust and lint trapped under the keys. The easiest way to do this is to blow dirt from under the keys using an aerosol can of air with a narrow, straw-like extension.

    If you spill liquid on the keyboard, turn off the computer and turn the unit upside down. Let the liquid drain, then let the keyboard dry before trying to use it again. If the keyboard does not work after it dries, you may need to replace it. Back to the top of the screen.

Cleaning the screen

    If your computer screen is an LCD panel, use a soft cloth and water to clean the screen. Squirt a little water on the cloth (never directly on the screen), and wipe the screen with the cloth.

 
 
Caution

An LCD screen is made of specially coated glass and can be scratched or damaged by abrasive or ammonia-based window cleaners. Please contact us so we can take care of this for you.

 

    - OR -

    If your computer screen is not an LCD panel, use a soft cloth and window cleaner to clean the monitor screen. Squirt a little cleaner on the cloth (never directly on the screen), and wipe the screen with the cloth.
