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 still need to handle it with care.
Note: If you power off the computer, wait at least 5 seconds before

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.

ThinkPad 240 User's Reference
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 10°C
or above 35°C (50°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 39 for information on a more appropriate model for demanding applications.
Do not crush, drop, or physically punish the external or remov-
able hard disk when it is outside your computer.
Do not insert a diskette into the external disk drive 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 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.

Maximizing battery-powered operation

Whenever possible, use the ThinkPad battery power-saving
modes:
Standby: The LCD and the hard disk drive are turned off. – Suspend: All tasks are stopped and stored in memory to
save power.
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.
Stop the power supply 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.

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.
Note: The example shown here is someone in a traditional setting.
Even when not in such a setting, you can follow many of these tips. Develop good habits, and they will serve you well.

Customizing the TrackPoint

Using the Press-to-Select page

If you enable Press-to-Select by putting a check mark in the Enable Press-to-Select box, you can make the TrackPoint stick function the
same as the left or right click button on the keyboard.
If you check Enable Dragging, you can drag the icon that you
select with the TrackPoint stick by putting light pressure on the stick.
If you check Enable Release-to-Select, you can click simply by
lifting your finger quickly off the TrackPoint. Moving the cursor onto an icon and then lifting your finger off the TrackPoint works like clicking. Pressing the TrackPoint again works like double­clicking.
Click one of the Press means radio buttons to select which
button the stick will simulate: either the left or the right button. For example, if you select Left Click, you can start a program with the TrackPoint by putting the pointer on the program's icon and applying light pressure on the stick.
To adjust the pressing timing of the stick, set Click Pace.

Using passwords

The password-setting feature helps to prevent your computer from being used by others. Once you set a password, a prompt appears on the screen each time you turn on the computer. You must enter your password at the prompt. You cannot use the computer unless you type the correct password. You can set the following passwords on your computer:
Power-on password
Set the power-on password to protect your computer from use by another person. It provides the following security features:
– You need to type the power-on password at startup. There-
fore, unauthorized users cannot use your computer.
– You need to type the power-on password when resuming
from suspend mode. Therefore, unauthorized users cannot use your computer.
Hard disk password
The hard disk password provides an extra measure of security. Even if you set a power-on password, another user can remove the hard disk drive in your computer and put it in a different com­puter to access your data. If you set a hard disk password, however, another person cannot access the data on your hard disk without knowing the password. It provides the following features:
– You need to type the hard disk password at startup. – If the hard disk drive is moved to another computer, the hard
disk password must be typed at startup. Therefore, unauthor­ized users cannot access your hard disk even if the drive is removed from the computer.
Note: The hard disk password might be disabled by your system
administrator.
Supervisor password
The supervisor password is a tool provided for the system administrator to control many ThinkPad computers. The super­visor password is set by the system administrator and it is not

required for users. Users can start the computer without pro­viding the supervisor password. The supervisor password is required only to access the BIOS Setup Utility. It provides the following security features:
– Only a system administrator can access the BIOS Setup
Utility. If a supervisor password is set, a password prompt appears if you try to start the BIOS Setup Utility.
– The system administrator can set the same supervisor pass-
word on many ThinkPads to make administration easier.
Other password
Some Microsoft operating systems provide special Windows passwords. Refer to that system's user's guide for information on how to set, change, and use these passwords.

Entering a password

Once you set a power-on password, a password prompt ( appears at the top left corner of the screen. This prompt appears each time you turn on your computer or when your computer returns from suspend mode to normal operation.
To enter a password, do the following:
1. Type your password. Don't hold down a key too long, because the same character will
be entered continuously.
2. Press the Enter key. An OK appears if you enter the correct password, and an X
appears if you enter the wrong password. If you fail to enter the correct password in three tries, you must turn off the computer, wait 5 seconds, and then turn it on again and retry.

If you type a wrong character, use the Backspace key to erase it and then type the correct one.
6. Type your password again and press Enter to verify it.
Note: Write down the password and keep it in a safe place.
Do Not Forget Your Password
If you forget your hard disk or supervisor password, there is no way to reset your password or recover data from the hard disk. You have to take your computer to an IBM reseller or IBM mar­keting representative to have the hard disk or the system board replaced. Proof or purchase is required, and an additional charge might be required for the service. Neither an IBM reseller nor IBM marketing representative can make the hard disk drive usable.

Changing or removing a password

This security feature prevents someone from removing a password and using your computer. To change or remove a password, do the following:
1. Restart the computer.
2. When the IBM logo is displayed, press F1 to enter the BIOS Setup Utility.
3. Select Password and press Enter. The "Password" submenu appears.
4. Select the type of password you want to change or remove, and press Enter. A window appears.

You can set any resolution for either the ThinkPad LCD or the external monitor. When you use both at the same time, the resolution of both is the same. If you set a higher resolution for the ThinkPad LCD, you can see only part of the screen at a time. You can see other parts by moving the image with the TrackPoint or other pointing device. You can change the display output type to the LCD, external monitor, or both with the Display Device buttons of the ThinkPad Configuration program or with Fn+F7.
You can set up the external monitor as follows:
1. Start the ThinkPad Configuration program.
