Appendix B. 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.
Take 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.
Other important tips
• Do not put the battery pack in trash that is disposed of in landfills. When
disposing of the battery, comply with local ordinances or regulations and
your company’s safety standards.
• Your computer might have both an Ethernet connector and a modem
connector. If so, be sure to connect your communication cable to the
correct one, so your connector is not damaged.
