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.
• Take care not to turn your computer over while the AC adapter is plugged in. This could
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.
• Before you install any of the following devices, touch a metal table or a grounded metal object.
This action reduces any static electricity from your body. The static electricity could damage
the device.
