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
Avoid inserting diskettes at an angle and attaching multiple or loose
diskette labels, as these can lodge in the drive.
v
If your computer comes with an optical drive such as a 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 the 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. See Access IBM, your on-board help
system, for information on replacing your hard disk drive (open Access
IBM by pressing the Access IBM button.).
Take care in setting passwords
v
Remember your passwords. If you forget a supervisor or hard disk
password, IBM 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. See Access IBM, your on-board help
system, for information on the location of these connectors (press the Access
IBM button to open Access IBM).
v
Register your ThinkPad products with IBM (refer to the Web page:
www.ibm.com/pc/register ). This can help authorities return your computer
to you if it is lost or stolen. Registering your computer also enables IBM to
notify you about possible technical information and upgrades.
v
Only an authorized IBM ThinkPad repair technician should disassemble
and repair your computer.
v
Do not modify or tape the latches to keep the display open or closed.
