Caring for your computer
v When picking up your open computer, hold it by the bottom. Do not pick
up or hold your computer by the display.
v Use a quality carrying case that provides adequate cushion and protection.
Do not pack your computer in a tightly packed suitcase or bag.
Handle storage media and drives properly
v If your computer comes with an optical drive such as CD, DVD, or
CD-RW/DVD drive, do not touch the surface of a disc or the lens on the
tray.
v Wait until you hear the CD or DVD click into the center pivot of an optical
drive such as CD, DVD, or CD-RW/DVD drive before closing the tray.
v When installing your hard disk, diskette, CD, DVD, or CD-RW/DVD drive,
follow the instructions shipped with your hardware, and apply pressure
only where needed on the device.
Take care in setting passwords
v Remember your passwords. If you forget a supervisor or hard disk
password, Lenovo authorized service provider will not reset it, and you
might have to replace your system board or hard disk drive.
Other important tips
v 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.
v 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.
v Register your Lenovo products with Lenovo (refer to the Web page:
www.lenovo.com/register). 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.
v Only an authorized Lenovo notebook repair technician should disassemble
and repair your computer.
v Do not modify or tape the latches to keep the display open or closed.
v Take care not to turn your computer over while the ac adapter is plugged
in. This could break the adapter plug.
v Store your external and removable hard disk, diskette, CD, DVD, and
CD-RW/DVD drives in the appropriate containers or packaging when they
are not being used.
