this information instead of the corresponding information in the

User's Reference

Fn key function

processor speed. Instead, the key combination switches between power modes as follows:

Setting for the TrackPoint

The

User's Reference

in the “Disabling the TrackPoint” section describes how to set Auto-Disable

if you are using certain mouse types, but actually the TrackPoint is set to Auto-Disable as the

default. With this setting, the TrackPoint is disabled automatically if a mouse is connected to the

external-input-device connector if any of the following is true:

– The system is starting.

– The system is resuming from suspend mode.

– Your computer is attached to the ThinkPad Port Replicator with Advanced EtherJet Feature.

If no external mouse is connected, the TrackPoint remains enabled.

A mouse that is compatible with the IBM PS/2 Miniature Mouse can work simultaneously with the

TrackPoint if the TrackPoint is set to Enable. To enable the TrackPoint, do as follows:

Start the ThinkPad Configuration program.

Click the TrackPoint ( ) button.

Click Enable for the TrackPoint.

User's Reference Supplement

Note: If you are using a mouse connected to the serial connector or the USB connector, you

should not use the TrackPoint at the same time. Select Disable rather than Enable or

Auto-Disable.

Solving computer problems

Suspend or hibernation problem

For this troubleshooting, disable the Ethernet port in the Windows NT environment as follows, rather

than using the procedure in the

User's Reference

Problem Cause and action

If you are using the port

replicator, resuming

normal operation from

hibernation or suspend

mode takes a long time.

This is not a problem. If you have not connected the network cable, the

computer queries the Ethernet until the timeout timer is reached. Connect

the network cable if you want to use the Ethernet. If you are not using the

network, disable the Ethernet port as follows:

For Windows 98:

1. Double-click a System icon in the Control Panel.

2. Click the Device Manager tab.

3. Double-click Network Adapter.

4. Double-click Intel EtherExpress PRO PCI Adapter.

5. Select the Disable in this hardware profile check box.

6. Click OK.

7. Close all windows.

8. Restart the computer.

For Windows NT:

1. Double-click the Devices icon in the Control Panel.

2. Select Intel EtherExpress PRO Adapter and click Stop.

3. Click Startup... and select Disabled.

4. Click OK.

5. Click Close.

6. Close all windows.

7. Restart the computer by powering it off and on again.
