Handling Tips
Register your ThinkPad products with IBM (refer to the
Setup Guide). 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 upgrades.
Check the IBM Web pages at http://www.pc.ibm.com periodically to get current information about your computer.
Cleaning Your Computer
Occasionally clean your computer as follows:
Use a soft cloth moistened with nonalkaline detergent to wipe the exterior of the computer.
Don't spray cleaner directly on the display or keyboard.
Gently wipe the LCD with a dry, soft cloth.
Carrying Your Computer
When carrying your computer, follow these instructions to prevent possible damage to your computer and data:
1. Remove any media from the CD-ROM drive or diskette drive.
2. Turn off all attached devices.
3. Power off the computer, or enter suspend or hibernation mode; then close the LCD. Make sure the suspend indicator is on
when it is in suspend mode, or the power indicator is off when it is powered off or in hibernation mode.
4. Unplug all external cables and cords connected to your computer.
5. Make sure all computer doors and covers are closed.
6. Use a quality carrying case that provides adequate cushion and protection.
Do not move the computer when the hard disk drive is accessing data (when the indicator is blinking). Make sure the indicator is
off before you carry the computer.
Extending Your Computer's Battery Life
The amount of battery power consumed by your computer depends on such conditions as the usage frequency, the operating
temperature, and the period in storage (if unused). The following tips can help you to extend the life of your battery:
If your battery is brand new and you are charging it for the first time, it might not become fully charged due to the
characteristics of the chemicals in the cell. To maximize performance, ensure that all chemicals in the battery are fully
activated by cycling the battery (fully charge, then fully discharge) three times. Also, follow this procedure if you stored the
battery for a few months.
Do not charge the battery pack until all of its power is used. Recharging a battery pack that is not completely discharged can
shorten battery life.
Once you start charging the battery pack, do not use it until it is fully charged.
Whenever possible, use the ThinkPad battery power-saving modes:
– Standby
– Suspend
– Hibernation

“Basic” in the
Online User's Guide.
Decrease the LCD brightness.
Use Advanced Power Management (APM). Each operating system comes with its own power management.
Stop the supply of power to the internal serial devices, including the modem, the serial port, and the infrared port, if they are
not in use.
Remove the battery pack and keep it in a cool place if you will not be using the computer for a long period.
Ruggedized Mobile Computers
Some professionals work in environments that may require special ruggedized features to protect their computers from extreme
temperature, humidity, and physical punishment. Construction, public service, distribution, repair service, and utilities are some of
the environmentally demanding professions that may require rugged mobile computers that can withstand stresses. For these
applications, IBM offers such computers (not ThinkPad systems), especially designed for mobile professionals who need a system
for managing and communicating information from the field.
For more information on these computers, consult your IBM Business Partner.
