Using the PC Card Slot

Note:
When installing an operating system, install the PC Card support software that is on the PC Card Installation Diskette before using the PC Card slots.

To install the PC Card support software:
"Installing Software".

The computer has two PC Card slots (upper and lower slot) to install two Type I or Type II PC Cards (one in each slot), a single Type III PC Card (in the lower slot), or a single Zoomed Video port card (in the lower slot).

This section explains how to install and remove a card from the PC Card slot. For information about operating the computer with PC Cards, refer to "Using PC Cards".

Installing a PC Card

1. Find the notched edge (1) of the card as shown.
   
   

   Note:
   If you are using a PC Card with an XJACK **  connector, insert it into the upper slot.
   If you are using a Zoomed Video port card, insert the card into the lower slot.

2. Insert the card into an appropriate slot according to your card type. Slot covers fold to the inside when you insert the cards:

   • If you are using a Type I or Type II PC Card, insert it into either the upper slot (A) or the lower slot (B).

   • If you are using a Type III PC Card, insert the card into the lower slot (B).
   
   
   

   Press the card firmly into the connector (1) until the eject button pops out (2). Then, pull the eject button out slightly and fold it to the right(3).

You have completed the installation of the card. Refer to the following sections:

• To use PC Cards, see "Using PC Cards".
• To use PC Cards with power-saving functions, see:
  • "Considerations for Suspend Mode".
  • "Considerations for Hibernation Mode".

Removing a PC Card

Raise the PC Card eject button (1) for the card you want to remove. Then, press the PC Card eject button (2) until the card pops out.

Remove the card (3) and save it for future use.

Increasing the Memory Capacity

Increasing the Memory Capacity

Note:
IC DRAM cards cannot be used with 380 or 380D computers.

Increasing the 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.

You can insert a DIMM directly in the memory slot on the bottom of the computer and expand your computer memory capacity.

Important
Changing memory while your computer is in suspend mode or hibernation mode may cause permanent damage to the equipment. Make sure you turn off the computer power when changing memory.

Installing or Removing the DIMM

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

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

2. Touch any metal object with your hand to release any static electricity.

3. Turn the computer over.

4. Loosen the screw on the memory slot cover and remove the cover.
   
   

5. Which are you going to do?

   Install a DIMM

   Go to the next step.

   Remove a DIMM

   Go to step 7.

6. Install the DIMM into the memory slot:

   1. Find the notches (A)and (B) on the edge of the DIMM.

   2. With the notched end of the DIMM toward the right side of the socket (B), insert the DIMM, at an angle of approximately 20°, into the socket; then press it firmly.

   3. Pivot the DIMM until it snaps into place.
      
      

   4. Go to step 8.

7.  Remove the DIMM from the memory slot:

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

   1. Press out on the latches on both edges of the socket at the same time.
      
      

   2. Remove the DIMM.

      Be sure to save the DIMM for future use.

   3. Go to the next step.

8.  Place the memory slot cover over the memory slot; then install the screw back into its place.
   
   

9. Turn the computer over again.

10. Open the LCD and power on the computer.

11. To confirm that the DIMM is correctly attached to the computer, do the following:

    Note:
    1Megabytes=1024Kilobytes

    1.  Calculate your total memory size in kilobytes (KB) by adding the DIMM memory size to the base memory size (16,384KB).

       For example, if you installed a 16Megabytes DIMM, calculate the total memory size as follows:

       16(Megabytes) x 1024(Kilobytes) + 16000(Kb) = 32384(KB)
       

       Note:
       To start Easy-Setup, press and hold F1; then turn on the computer.

    2. Start Easy-Setup and confirm the memory size count at the upper left corner of the screen as shown:

       +--------------------------------------------------+
       | 032384 KB OK                                     |
       |                                                  |
       |                                                  |
       |                                                  |
       +--------------------------------------------------+
       

       
       

       If a 201 error code appears under the memory count, turn off the computer and go to reference #80 to reinstall the DIMM.

       +-------------------------+
       | 032384 KB OK            |
       |                         |
       | 201                     |
       |                         |
       +-------------------------+
       

       
       

    3. Is the total memory size the same as the value you calculated in step 1?

       Yes

       Go to the next step.

       No

       Turn off the computer and go to reference #80 to reinstall the DIMM.

    4. Select Test from the main menu of Easy-Setup; then select Memory.

       The memory test starts.

       Note:
       It may take some time to complete the memory test.

    5. Does an OK message now appear under the Memory icon?

       Yes

       You have installed the DIMM correctly. Exit Easy-Setup and go to the next step.

       No

       You need to reinstall the DIMM. Go to reference #80 and reinstall the DIMM.

12. Reconnect all cables.

You have completed the installation or removal of the DIMM.

Important
If you changed the memory installed in the computer and were using hibernation mode, you need to create a new hibernation file. See "Creating the Hibernation File".

Attaching an External Numeric Keypad or a Mouse

Attention:

When you connect a mouse other than an IBM PS/2 Miniature Mouse, turn off the computer.
Be careful not to insert the connector upside down

An external numeric keypad or a mouse can be attached directly to the connector on the rear of the computer. You can use both the IBM PS/2 Miniature Mouse and TrackPoint III as the pointing device.

Note:
You can remove the keypad cover (1) and use it as a stand for the keypad.



If you want to use the external numeric keypad and mouse at the same time, first connect the keypad cable to the computer; then connect the mouse cable (2) to the connector at the rear of the keypad.

(Ref #82.)

Using the Mouse and Other Pointing Devices

Note:
The appropriate software must have already been installed.

A serial mouse connected to the serial port or a device that is not compatible with the PS/2 Mouse can be connected to the external input-device connector. Some mouse types require the TrackPoint III to be disabled before you can use them. To disable the TrackPoint III:
With OS/2 or Windows:

1. Start the ThinkPad Features program.

2. Click on the Keyboard/Pointing-Device () icon.

3. Click on Disable for the TrackPoint.

   These changes become effective when computer power is turned off and then on again.

Attaching an External Keyboard

You can connect an external keyboard to your computer through the keyboard/mouse connector (1) (available separately as an option).

Note:
The computer enters suspend mode when the LCD is closed. If you want to use the computer with the LCD closed, set the suspend option in the ThinkPad Features program so the computer does not enter suspend mode when the LCD is closed.
Be careful not to insert the connector () upside down.

ThinkPad Features program:
reference #15.

The external keyboard must be connected through the keyboard/mouse connector. It will not work if it is connected directly to the computer.

When the external keyboard is attached, the following keys are not available:

• Numeric keypad on the computer keyboard.

• External numeric keypad.

When you attach the external keyboard, turn off the computer, attach the keyboard to the keyboard/mouse connector (), and then attach the keyboard/mouse connector to the computer ().
