Description:

The tp4ex.exe file enables Track point accessibility features for IBM and is installed along with IBM laptop drivers. The process is loaded during start-up of Windows to enable the device for the IBM ThinkPad. The tp4ex.exe file enables the use of the track pointing device, also called the touchpoint mouse that is built in the keyboard of IBM laptops.

The tp4ex.exe file is responsible for allowing the management of accessibility features for the IBM Trackpoint. This unique device for cursor pointing is unique for IBM ThinkPads and lets users select and drag so they can perform without moving their fingers from their typing position. The IBM Trackpoint is a red stick that is visible on the keyboard with three click buttons below the Space bar. The movement of the pointer depends on the control and degree of pressure that you apply on the non-slip cap of the pointing stick.

The material is slightly rough, operating by sensing an applied force. It can be in any direction that is parallel to the keyboard but the pointing stick itself does not move. The speed at which it moves depends on the pressure that a user applies on the stick. Click button functions depend on the tp4ex.exe file so users can configure it to their preference.

The tp4ex.exe process enables accessibility options for users of the stick contained in between the b, g, and h keys on the IBM ThinkPad. It is set apart from other laptop devices as it has no moving parts. It functions by utilizing a solid state strain gauge. The pointing stick is tapped if users want to perform left-click as an alternative to using the left button on a mouse. The tp4ex.exe process also allows users to program the sensitivity of the IBM Trackpoint and can be adjusted for a very light touch.
