Handling Your Computer
Handling Your Computer
By using common sense and by following these handling tips, you will get the most use and enjoyment out of your ThinkPad computer for a long time to come.
Notebook computers are precision machines that require a bit of careful handling. Though the IBM ThinkPad computer is designed and tested to be a durable notebook computer that functions reliably in normal work environments, you need to use some common sense when handling it.
Note:
If you power off the computer, wait at least 5 seconds before you power it on again.
ThinkPad Don'ts
Do not subject your computer to physical punishment, such as dropping or bumping.
Do not place heavy objects on your computer.
Do not spill or allow liquids into your computer.
Do not use your computer in or near water (to avoid the danger of electrical shock).
Do not pack your computer in a tightly packed suitcase or bag.
The compression might cause internal damage.
Do not disassemble your computer. Only an authorized IBM
ThinkPad repair technician should disassemble and repair your computer.
Do not scratch, twist, hit, or push the surface of your computer display.
Do not place any objects between the display and the keyboard.
Do not pick up or hold your computer by the display. When picking up your open computer, hold it by the bottom (keyboard) half.
Do not modify or tape the latches to keep the display open or closed.

Handling Your Computer
Do not turn your computer over while the AC Adapter is plugged in. This could break the adapter plug.
Do not use your computer when the temperature is below 5°C or above 35°C (41°F to 95°F).
Do not place your computer closer than 13 cm (5 in.) from any electrical appliance that generates a strong magnetic field, such as a motor, a magnet, a TV, a refrigerator, or large audio speakers.
Do not hard-mount your computer in a vehicle or anywhere that it is subject to strong vibration. See “Ruggedized Mobile
Computers” on page 41 for information on a more appropriate model for demanding applications.
Do not press on the middle part of the CD-ROM drive.
Do not insert a diskette at an angle. Not inserting the diskette straight into the drive can damage the head.
Do not place more than one label on a diskette. Multiple or loose labels can detach or tear and then lodge in the drive.
Do not touch the lens on the CD-ROM tray.
Do not touch the surface of a compact disc; handle the compact disc only by its edges.
Do not connect the modem to a PBX (private branch exchange) or other digital telephone extension line. Your computer can
use only a public-switched telephone network (PSTN). Use of a phone line other than PSTN can damage your modem. If you are not sure which kind of phone line you are using, contact your telephone company. Many hotels or office buildings use digital telephone extension lines, so check before connecting the telephone cable in such places.
Do not leave the base of your computer in contact with your lap or any part of your body for an extended period when the computer is functioning or when the battery is charging. Your computer dissipates some heat during normal operation. This heat is a function of the level of the system activity and battery charge level.

ThinkPad Do's
Treat your computer like a precision piece of electronic machinery.
Retain and store packing materials safely out of reach of children to prevent the risk of suffocation from plastic bags.
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 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 a nonalkaline detergent to wipe the exterior of the computer.
Don't spray cleaner directly on the display or the keyboard.
Gently wipe the LCD with a dry, soft cloth. Avoid using alcohol or detergent to clean the LCD.
Carrying the Computer
When carrying the 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. Turn off the computer and close the LCD.
4. Unplug all external cables and cords connected to the computer.
5. Make sure all computer doors and covers are closed.
6. Use a quality carrying case that provides adequate cushion and protection.

Handling Your Computer
Preserving Battery Pack 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 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. This procedure is also recommended 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 dishcarged can shorten battery life.
Once you start charging the battery pack, do not use it until it is fully charged.
Maximizing Battery-Powered Operation
Whenever possible, use the ThinkPad battery power-saving modes:
– Standby: The LCD and the hard disk drive are turned off.
– Hibernation: All tasks are stopped. The memory data and the current status of the computer are stored in the hard disk drive; then the power is turned off.
Decrease the LCD brightness.
Use Advanced Power Management (APM). Each operating system comes with its own APM.
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 envi-

ronmentally 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.

Ergonomics Information
This is important information you should read before using your portable ThinkPad computer in your "virtual office".
Working in the virtual office may mean adapting to frequent changes in your environment. Following some simple "rules of the road" will make things easier and bring you the maximum benefits of your
ThinkPad computer. Keeping in mind such basics as good lighting and proper seating, for example, can go a long way in helping you enhance your performance and achieve greater comfort wherever you are.
What if I am traveling?
It may not be possible to observe the best ergonomic practices when you are using the ThinkPad computer while on the move or in a
"casual" setting. Regardless of the setting, try to observe as many of the tips for proper usage as possible. Sitting properly and using adequate lighting, for example, will help you maintain desirable comfort and performance levels.
Questions about vision?
IBM's visual display screens are designed to meet the highest standards and to provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the eyes. Of course, any concentrated and sustained visual activity can be tiring. If you have questions on eye fatigue or visual discomfort, consult a vision care specialist for advice.
