Be sure to follow the important tips given here to continue to get the most use
and enjoyment out of your computer. Failure to do so might lead to
discomfort or injury, or cause your computer to fail.
Protect yourself from the heat that your computer generates.
When your computer is turned on or the battery is
charging, the base, the palm rest, and some other parts may
become hot. The temperature they reach depends on the
amount of system activity and the level of charge in the
battery.
Extended contact with your body, even through clothing,
could cause discomfort or even a skin burn.
v Avoid keeping your hands, your lap, or any other part of
your body in contact with a hot section of the computer
for any extended time.
v Periodically take breaks from using the keyboard by lifting
your hands from the palm rest.
Protect yourself from the heat generated by the AC adapter.
When the AC adapter is connected to an electrical outlet
and your computer, it generates heat.
Extended contact with your body, even through clothing,
may cause a skin burn.
v Do not place the AC adapter in contact with any part of
your body while it is in use.
v Never use it to warm your body.
Prevent your computer from getting wet.
To avoid spills and the danger of electrical shock, keep
liquids away from your computer.
© Copyright Lenovo 2007 v
Protect the cables from being damaged.
Applying strong force to cables may damage or break them.
Route communication lines, or the cables of an AC
adapter, a mouse, a keyboard, a printer, or any other
electronic device, so that they cannot be walked on,
tripped over, pinched by your computer or other objects,
or in any way subjected to treatment that could interfere
with the operation of your computer.
Protect your computer and data when moving it.
Before moving a computer equipped with a hard disk drive,
do one of the following, and make sure that the power
switch is not lit:
– Turn it off.
– Press Fn+F4 to put it in sleep (standby) mode.
– Press Fn+F12 to put it in hibernation mode.
This
will help to prevent damage to the computer, and
possible loss of data.
Handle your computer gently.
Do not drop, bump, scratch, twist, hit, vibrate, push, or
place heavy objects on your computer, display, or external
devices.
Carry your computer carefully.
v Use a quality carrying case that provides adequate
cushioning and protection.
v Do not pack your computer in a tightly packed suitcase
or bag.

Chapter 2. Taking care of your ThinkPad computer
Though your computer is designed to function reliably in normal work
environments, you need to use common sense in handling it. By following
these important tips, you will get the most use and enjoyment out of your
computer.
For the most important instructions for using your computer, see “Read this
first” on page v.
Important tips
Be careful about where and how you work
v Store packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
v Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm or 5″).
v Avoid subjecting your computer to extreme temperatures (below 5°C/41°F
or above 35°C/95°F).
v Some appliances, such as certain portable desktop fans or air purifiers, can
produce negative ions. If a computer is close to such an appliance, and is
exposed for an extended time to air containing negative ions, it may
become electrostatically charged. Such a charge may be discharged through
your hands when you touch the keyboard or other parts of the computer,
or through connectors on I/O devices connected to it. Even though this
kind of electrostatic discharge (ESD) is the opposite of a discharge from
your body or clothing to the computer, it poses the same risk of a computer
malfunction.
Your computer is designed and manufactured to minimize any effects of
electrostatic charge. An electrostatic charge above a certain limit, however,
can increase the risk of ESD. Therefore, when using the computer close to
an appliance that can produce negative ions, give special attention to the
following:
– Avoid directly exposing your computer to the air from an appliance that
can produce negative ions.
–
Keep your computer and peripherals as far as possible from such an
appliance.
– Wherever possible, ground your computer to facilitate safe electrostatic
discharge.
© Copyright Lenovo 2007 3
Note: Not all such appliances cause a significant electrostatic charge.
Be gentle with your computer
v Avoid placing any objects (including paper) between the display and the
keyboard or the palm rest.
v Your computer display is designed to be opened and used at an angle
slightly greater than 90 degrees. Do not open the display beyond 180
degrees, as this might damage the computer hinge.
v Do not turn your computer over while the AC adapter is plugged in. This
could break the adapter plug.
Register your computer
v Register your ThinkPad products with Lenovo (visit the following Web site:
http://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.
Carry your computer properly
v Before moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
v When picking up your open computer, hold it by the bottom. Do not pick
up or hold your computer by the display.
Handle storage media and drives properly
v If your computer comes with an optical drive:
– Do not touch the surface of a disc or the lens on the tray.
– Wait until you hear the CD or DVD click into the center pivot of an
optical drive before closing the tray.
– To remove a disc, pull out the drive tray until it stops. Insert your thumb
in the opening at the corner of the tray, so that you can easily pull up
the disc and remove it from the tray.
– The empty disc tray of the optical disc drive may not come out as
quickly as you expect when you press the eject button. But the delay is
normal. When no disc is in the optical drive, the drive is automatically
turned off to save energy. Then, when you press the eject button, it takes
a little while to turn on the optical drive and pull out the disc tray. If
you need to pull out the tray immediately, press the eject button again.

X300 Service and Troubleshooting Guide
v When installing the HDD, SSD, or optical drive, follow the instructions
shipped with your hardware, and apply pressure only where needed on the
device.
v Turn off your computer if you are replacing the HDD or SSD.
v When replacing the primary HDD or SSD, reattach the cover of the drive
slot.
v Store your external and removable hard disk or optical drives in the
appropriate containers or packaging when they are not being used.
v 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.
– Memory module
– PCI Expess Mini Card
Be sure not to modify your computer
v Only an authorized ThinkPad repair technician should disassemble and
repair your computer.
v Do not modify or tape the latches to keep the display open or closed.
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 HDD or SSD.
Care for the fingerprint reader
The following actions could damage the fingerprint reader or cause it not to
work properly:
v Scratching the surface of the reader with a hard, pointed object.
v Scraping the surface of the reader with your nail or anything hard.
v Using or touching the reader with a dirty finger.
If
you notice any of the following conditions, gently clean the surface of the
reader with a dry, soft, lint-free cloth:
v The surface of the reader is dirty or stained.
v The surface of the reader is wet.
v The reader often fails to enroll or authenticate your fingerprint.
Cleaning the cover of your computer
Occasionally clean your computer as follows:
1. Prepare a mixture of a gentle kitchen-use detergent (one that does not
contain abrasive powder or strong chemicals such as acid or alkaline). Use
5 parts water to 1 part detergent.
2. Absorb the diluted detergent into a sponge.
Chapter 2. Taking care of your ThinkPad computer 5
3. Squeeze excess liquid from the sponge.
4. Wipe the cover with the sponge, using a circular motion and taking care
not to let any excess liquid drip.
5. Wipe the surface to remove the detergent.
6. Rinse the sponge with clean running water.
7. Wipe the cover with the clean sponge.
8. Wipe the surface again with a dry, soft lint-free cloth.
9. Wait for the surface to dry completely and remove any cloth fibers from
the computer surface.
Cleaning your computer keyboard
1. Absorb some isopropyl rubbing alcohol on a soft, dust-free cloth.
2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you
wipe several keys at a time, the cloth may hook onto an adjacent key and
possibly damage it. Make sure that no liquid drips onto or between the
keys.
3. Allow to dry.
4. To remove any crumbs and dust from beneath the keys, you can use a
camera blower with a brush or cool air from a hair drier.
Note: Avoid spraying cleaner directly on the display or the keyboard.
Cleaning your computer display
1. Gently wipe the display with a dry, soft lint-free cloth. If you see a
scratch-like mark on your display, it might be a stain transferred from the
keyboard or the TrackPoint® pointing stick when the cover was pressed
from the outside.
2. Wipe or dust the stain gently with a soft, dry cloth.
3. If the stain remains, moisten a soft, lint-free cloth with water or a 50-50
mixture of isopropyl alcohol and water that does not contain impurities.
4. Wring out as much of the liquid as you can.
5. Wipe the display again; do not let any liquid drip into the computer.
6. Be sure to dry the display before closing it.
