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. 16
