Lenovo 4223 Good maintenance practices, Moving your computer, Cleaning a glass-screen surface

Page 96

Many computer supply stores carry the special cleaning fluids for displays. Use cleaning fluids developed for LCD displays only. First apply the fluid to a lint-free, soft cloth, then clean the LCD display. Some computer supply stores carry pre-moistened towelettes for LCD maintenance.

Cleaning a glass-screen surface

To clean a glass-screen surface, wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and other loose particles. Then use a soft cloth moistened with a nonabrasive liquid glass cleaner.

Good maintenance practices

By performing a few good maintenance practices, you can maintain good computer performance, protect your data, and be prepared in case of a computer failure.

•Empty your recycle bin on a regular basis.

•Run the Windows Disk Defragmenter program occasionally to prevent performance problems caused by an excessive number of fragmented files.

•Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.

•Make backup copies of critical data on removable media memory at regular intervals and store the removable media in a safe location. The frequency of making backup copies depends on how critical the data is to you or your business. Lenovo makes a number of removable-media storage devices available as options, such as CD-RW drives and recordable DVD drives.

•Back up your entire hard disk drive on a regular basis.

•Keep your computer software up-to-date. See “Keeping your computer current ” on page 81 for more information.

•Keep a log book. Entries might include major software or hardware changes, device-driver updates, intermittent problems and what you did to resolve them, and any minor issues you might have experienced. A log book can help you or a Lenovo technician determine if a problem is related to change in hardware, change in software, or some other action that might have taken place.

•Create Product Recovery discs. See “Creating and using recovery media” on page 59 for more information about using Product Recovery discs to restore the hard disk drive to the factory default settings.

•Create rescue media. See “Creating and using a rescue medium” on page 62 for more information about using a Rescue medium such as a CD or DVD to recover from failures that prevent you from gaining access to the Windows environment or the Rescue and Recovery workspace on your hard disk drive.

Moving your computer

Take the following precautions before moving your computer.

1.Back up all files and data from the hard disk drive. There are a variety of backup programs available commercially. Your operating system also might have a backup program that you can use. Lenovo provides the Rescue and Recovery program to help you back up and restore data. See “Performing backup and recovery operations” on page 60 for more information.

2.Remove all media (diskettes, compact discs, tapes, and so on) from the drives.

3.Turn off the computer and all attached devices. Your hard disk drive automatically parks the read/write head in a nondata area. This prevents damage to the hard disk drive.

4.Unplug the power cords from electrical outlets.

5.Disconnect communication cables, such as modem or network cables, from the outlets first, and then disconnect the other ends from the computer.

6.Note where any remaining cables are attached to the computer; then, remove them.

7.If you saved the original shipping cartons and packing materials, use them to pack the units. If you are using different cartons, cushion the units to avoid damage.
