Cleaning a flat-panel monitor surface
To clean the flexible film surface of a flat-panel computer display, wipe it gently with a soft, dry cloth, or
blow on the screen to remove grit and other loose particles. Then moisten a cloth with LCD cleaner and
wipe the screen surface.
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.
• Use the disk defragmentation or disk optimization feature of your operating system 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.
• Back up critical data regularly on removable media memory, such as discs and USB storage devices,
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.
• Back up your entire hard disk drive on a regular basis, see Recovery information.
• Keep your computer software, device drivers, and operating system up-to-date. See “Keeping your
computer current ” on page 77.
• 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 other issues you might have experienced.
The cause of a problem might be change in hardware, change in software, or any other actions that might
have taken place. A log book can help you or a Lenovo technician determines the cause of a problem.
• Create Product Recovery discs. See “Creating and using recovery media” on page 103 for more
information about using Product Recovery discs to restore the hard disk drive to the factory-default
settings.
• Create rescue media using discs or USB storage devices as early as possible. You can use a rescue
medium 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. If you use the Windows 7 operating system, Lenovo provides the Rescue and Recovery
program to help you back up and restore data. See “Performing backup and recovery operations” on
page 104.
2. Remove all media from your computer, such as discs, USB storage devices, memory cards, and so on.
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.
