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 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.
