Applicable Operating Systems:
-----------------------------
This fix applies to the following Operating Systems:
 
  - OS/2
 
 
Symptom:
--------
External trackpoint keyboard reset can occur while typing
on the external keyboard in the following configuration:
 
  - TP760 (all)
  - External Trackpoint keyboard attached through Y-cable or through
    Dock.
  - Internal Trackpoint device enabled
 
When the reset occurs, the keyboard LEDs flash and some keystrokes are
lost.
 
 
Fix:
----
During boot, the YPTF$035.SYS driver checks for the presence of an
external trackpoint device. If one is detected, it automatically
disables the internal trackpoint device.
 
 
Installation:
-------------
1. Copy YPTF$035.SYS to the directory of your choice on your hard
   disk drive.
2. Add the following line to the beginning of your CONFIG.SYS file:
 
         DEVICE=C:\path\YPTF$035.SYS
 
   where path indicates the directory where installed.
3. Ensure that the internal trackpoint is enabled using ThinkPad
   Features.
4. Shutdown and reboot for the change to take effect.
