TP General - Keyboard does not function after installing TrackPoint drivers under Windows NT

Applicable to: World-Wide

SYMPTOM:
After installing the TrackPoint drivers, and then rebooting as instructed, the keyboard no longer functions.

CONFIGURATION:
This may occur on any ThinkPad equipped with the TrackPoint device with Windows NT installed.

SOLUTION:

1. Restart the system.
2. When prompted to Press spacebar NOW to invoke Hardware Profile/Last Known Good, press the spacebar.
3. Press L to switch to the Last Known Good configuration listing, and then choose the appropriate Hardware Profile (NOTE: Hardware profiles will vary depending on how you have configured the system).
4. The system will boot and you will be able to logon to Windows NT, but the TrackPoint drivers will no longer be installed. Reinstall the TrackPoint drivers, but do not reboot.
5. Open Devices from the Control Panel. In the list of devices you will find that the i8042 Keyboard and PS/2 Mouse Port has been disabled. Select the i8042 Keyboard and PS/2 Mouse Port device and then click on the Startup... button. Change the Startup Type to System and click OK.
6. Close Devices and reboot the system so that the changes take effect.

ADDITIONAL INFORMATION:
Installing the TrackPoint drivers in Windows NT does not always produce this issue.
