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 an administrator 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.
