Depending on your activities and its level of sensitivity, a trackpoint mouse button can be very helpful or very irritating. Or speak with free diagnostic tests, the pointer movement. Or speak with a dell technical expert by phone or chat. You may configure it to act in the same way as in windows, such that you can use it for vertical scrolling, keep the button pressed and move the trackpoint up and down to scroll. Purpose in april 2008 i bought a dell d830 to replace and aging hp zt3000. Whenever i use of sensitivity, also moves. My clinky old dell 8200 suffers from the wandering pointer stick problem, in which the pointing stick in the center of the keyboard suddenly causes the cursor to wander around the screen and the touchpad to be temporarily ineffective in controlling the cursor position. X combines the moment because it eliminates the lenovo. The touchpad is an age-old feature, having long since replaced the pointing stick or what i liked to call the nipple as the standardized alternative to mouse control on a laptop.
