Display screen
Dust buildup compounds problems associated with glare. Remember to clean your monitor screen
periodically.
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.
• Keep your computer software, device drivers, and operating system up-to-date. See "Keeping your
computer current " on page 69.
• Empty your recycle bin on a regular basis.
• Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.
• Clean up files and free up storage drive space and memory space occasionally to prevent performance
problems. See "Performance and lockup problems" on page 81.
• 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 determine the cause of a problem.
• Back up your data on the storage drive regularly. You can restore the storage drive from a backup.
To back up your data, do one of the following:
– For Windows 7: Open the Rescue and Recovery program. See "Accessing a program on your
computer" on page 40. For more information about backing up your data, refer to the help system
of the program.
– For Windows 8.1: Open Control Panel. View Control Panel using Large icons or Small icons, and then
click File History. Follow the instructions on the screen.
Note: For detailed information on how to open Control Panel on Windows 8.1, see "Accessing Control
Panel on the Windows 8.1 operating system" on page 49.
– For Windows 10: Right-click the Start button to open the Start context menu, and then click Control
Panel. View Control Panel using Large icons or Small icons, and then click File History. Follow the
instructions on the screen.
• Create a recovery medium as early as possible. You can use the recovery medium to recover your
operating system even if Windows fails to start up.
To create a recovery medium, do one of the following:
– For Windows 7: Open the Create Recovery Media program. See "Accessing a program on your
computer" on page 40. For more information about creating a recovery medium, refer to the help
