Take Care in Setting Passwords
ƒ
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
ƒ
Your computer modem might use only an analog telephone network, or
public-switched telephone network (PSTN). Do not connect the modem
to a PBX (private branch exchange) or any other digital telephone
extension line because this could damage your modem. Analog phone
lines are often used in homes, while digital phone lines are often used in
hotels or office buildings. If you are not sure which kind of phone line
you are using, contact your telephone company.
ƒ
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.
ƒ
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.
ƒ
Only an authorized Lenovo repair technician should disassemble and
repair your computer.
ƒ
Do not modify or tape the latches to keep the display open or closed.
ƒ
Take care not to turn your computer over while the AC adapter is
plugged in. This could break the adapter plug.
