Chapter 2. Use and care Information
■
Data safety
• Do not delete unknown files or change the name of files or directories that
were not created by you; otherwise, your computer software might fail to
work.
• Be aware that accessing network resources can leave your computer
vulnerable to computer viruses, hackers, spyware, and other malicious
activities that might damage your computer, software, or data.
• It is your responsibility to ensure that you have adequate protection in the
form of firewalls, antivirus software, and anti-spyware software and keep
this software up to date.
■
Taking care in setting passwords
• Remember your passwords. If you forget a supervisor or hard disk
password, Lenovo authorized service providers will not reset it, and you
might have to replace your system board or hard disk drive.

Cleaning the cover of your computer
Occasionally clean your computer as follows:
1 Prepare a mixture of a gentle kitchen-use detergent (one that does not
contain abrasive powder or strong chemicals such as acid or alkaline).
Use 5 parts water to 1 part detergent.
2 Absorb the diluted detergent into a sponge.
3 Squeeze excess liquid from the sponge.
4 Wipe the cover with the sponge, using a circular motion and taking care
not to let any excess liquid drip.
5 Wipe the surface to remove the detergent.
6 Rinse the sponge with clean running water.
7 Wipe the cover with the clean sponge.
8 Wipe the surface again with a dry, soft lint-free cloth.
9 Wait for the surface to dry completely and remove any cloth fibers from
the computer surface.
Note: Shut down the computer and then disconnect the power cord before
cleaning the computer.
