Windows operating systems automatically apply a generic driver that allows users to benefit from basic touch functions; however, advanced features will not be available until the proper files are installed.

Connect and share knowledge within a single location that is structured and easy to search. I downloaded a new touchpad driver from the Lenovo support website. It said it was for Synaptics, Elan, Alps. I clicked to install, and it looked like it was going to install Synaptics, which is what I want; but the text was cut off so I wasn't sure. No choice was made available.

A pointing stick or trackpoint , also referred to generically as a nub or nipple is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice , touchpads or trackballs , operating system software translates manipulation of the device into movements of the pointer on the computer screen. Unlike other pointing devices, it reacts to sustained force or strain rather than to gross movement, so it is called an "isometric" [1] pointing device. IBM introduced it commercially in on its laptops under the name "TrackPoint", and patented an improved version of it in but the patent expired in The pointing stick senses applied force by using two pairs of resistive strain gauges. A pointing stick can be used by pushing with the fingers in the general direction the user wants the pointer to move. The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. The relation between pressure and pointer speed can be adjusted, just as mouse speed is adjusted. The mouse buttons can be operated right-handed or left-handed due to their placement below the keyboard along the centerline. Pointing sticks typically have a replaceable rubber cap, called a nub, which can be a slightly rough "eraser head" material or another shape. The cap is red on ThinkPads, but is also found in other colors on other machines. Button configurations vary depending on vendor and laptop model. ThinkPads have a prominent middle mouse button, but some models have no physical buttons.

If your laptop's trackpad is locked, it could be due to a few reasons:. Just as there are multiple reasons why your laptop mouse is locked, there are a few different ways to fix it. These steps are useful if you have another mouse attached to your laptop if you don't, skip down to the keyboard directions below. Some Lenovo laptops include a TrackPoint, a miniature pointing stick embedded between the G and H keys.

Windows operating systems automatically apply a generic driver that allows users to benefit from basic touch functions; however, advanced features will not be available until the proper files are installed. When enabled by required software, the touchpad component is recognized by computers and all developed features are made accessible. Even though touchpoint technology is mostly associated with notebooks or laptops, other systems can also benefit from it with the help of an external wireless or wired TouchPad device. If you wish to update to this version, know that it can enhance overall performance and stability, add different fixes for various touch problems, improve existing gestures, or even include support for new ones.

During later years, they faced a decline in popularity as most laptop-producing brands switched to touchpads, although as of , some manufacturers like Lenovo still produce laptops with pointing sticks.

Lenovo Synaptics touch pad driver installation Ask Question. The pointing stick senses applied force by using two pairs of resistive strain gauges. Modified 8 years ago. Down the rabbit hole in the Stack Exchange network. Because the amount of motion is small, the sensitivity of the sensors must be high, and they are subject to noise interference. In time, the software will re-calibrate and stop the motion. Selker built a model of a device that would minimize this time. The velocity of the pointer depends on the applied force so increasing pressure causes faster movement.
