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.
• Register your Lenovo products with Lenovo (refer to the Web page:
http://consumersupport.lenovo.com
). This can help authorities return your computer to you
if it is lost or stolen. Registering your computer also enables Lenovo to notify you about
possible technical information and upgrades.
• Only an authorized Lenovo repair technician should disassemble and repair your computer.
• Do not modify or tape the latches to keep the display open or closed.

break the adapter plug.
• Turn off your computer if you are replacing a device, or else verify that the device is warm- or
hot-swappable.

This action reduces any static electricity from your body. The static electricity could damage
the device.
