IBM Thinkpad Mouse Util – TP4SERV.EXE
TP4SERV.EXE comes installed on some older IBM Thinkpad Notebook PCs. Under some versions of windows, it is necessary for the 'scroll button' on the Thinkpad Trackpoint 'eraser head' mouse.
If you're not experiencing problems with it, we'd recommend leaving it in place. For more information, visit http://www.ibm.com/support/us/ then click "ThinkPad" and select your model. To download the latest IBM Trackpoint software, visit http://trackpoint.almaden.ibm.com/.
