Chapter 1. Getting Familiar with Your Computer 33

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 37 for information on a more appropriate model for demanding applications.

 Do not crush, drop, or physically punish the external or remov-

able hard disk, or bay device when it is outside your computer.

 Do not press on the middle part of the diskette drive or CD-ROM

drive.

 Do not insert a diskette at an angel. 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

Handling Your Computer

Preserving Battery Pack Life

6. Use a quality carrying case that provides adequate cushion and protection.

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. – 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.

ThinkPad 390 User's Reference

Handling Your Computer

 Remove the battery pack and keep it in a cool place if you will

not be using the computer for a long period.

Creating the Hibernation Function

Your computer can enter hibernation mode if you create the hibernation function.

Note: Hibernation works only in Windows 98 or Windows 95.

There are two ways you can create the hibernation function:  File-based hibernation

Note: Defragment your hard disk drive before creating a

hibernation file.

 Partition-based hibernation

For Windows 98 and Windows 95:

To create the hibernation file or partition, do as follows:

1. Turn off your computer.

2. Insert the Hibernation Utility Diskette into the diskette drive.

Note: You can create the Hibernation Utility

Diskette using the Diskette Factory (see “Using the Diskette Factory” on page 118).

3. Turn on the computer.

4. Follow the instructions on the screen.

Note: If you change the memory size, you need to

re-create the hibernation file or partition. For partition-based hibernation, use the hibernation utility to delete the partition first before creating a new one.

Increasing Memory

Increasing memory capacity is an effective way to make programs run faster. You can increase the amount of memory in your computer by installing a dual inline memory module (DIMM), available as an option.

Different capacities of DIMM are available. You can install DIMMs directly in the memory slots on the bottom of the computer. Your computer memory capacity can be expanded up to 256 MB (two 128 MB DIMM options).

Note: Base memory (32 MB or 64 MB) occupies one DIMM slot.

Attention: The ThinkPad 390 computer supports the static dynamic

random access memory (SDRAM) card only. It does not support the enhanced data output dynamic random access memory (EDO DRAM) card. If you install a DIMM that is not supported by your computer, an error code might appear when the system starts. The appropriate memory option can be purchased through your IBM reseller or IBM marketing representative.

To install the DIMM, do the following:

1. Power off the computer; then disconnect the AC Adapter and all cables from the computer.

2. Close the LCD, turn the computer over, and then remove the battery pack.

3. Loosen the screw on the memory slot cover; then remove the cover.

4. Install the DIMM into the memory slot.

Attention: To avoid damaging the DIMM, do not touch its contact edge.

a. Find the notch on the side of the DIMM. b. With the notched end of the DIMM toward the right side of

the socket, insert the DIMM, at an angle or approximately 20°, into the socket; then press it firmly (1).

c. Pivot the DIMM until it snaps into place (2).

If you want to install two DIMMs, repeat these steps.

5. Replace the memory slot cover over the memory slot, aligning

the back side of the cover first as shown; then tighten the screw.

2. If you changed the memory installed in the computer, you need to create a new hibernation file. To create the hibernation file

“Creating the Hibernation Function” on page 37 or "Basic" in

the Online User's Guide.

How to Calculate Total Memory Size

Calculate your total memory size in kilobytes (KB) by adding the DIMM memory size to the base memory size (32384 KB for a computer with 32 MB base memory).

Note: 384 KB is reserved by the system.

For example, if you installed a 32MB DIMM to a computer with 32 MB base memory, you should have about 64 MB.

ThinkPad 390 User's Reference

Increasing Memory

Your computer displays the memory size in kilobytes. For example, 640 KB (system memory) + 64512 (extended memory) = 65152 KB.

Removing the DIMM

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.

 Setup password

The setup password is a tool provided for the system administrator to control many ThinkPad computers. The setup password is set by the system administrator and it is not required for users.

ThinkPad 390 User's Reference

Using Passwords

Users can start the computer without providing the setup password. The setup 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 setup password is set, a password prompt appears if you try to start the BIOS Setup Utility.

– The system administrator can set the same setup password

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. Each time you turn on your computer or when your computer returns from suspend mode to normal operation.

However, a password prompt is not displayed if the computer returns to normal operation by a preset timer or an incoming call on the modem, in which case you will have to display it by pressing a key or moving the pointing device.

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.
