Lenovo Thinkpad Cursor Problems
TrackPoint drift is due to the autocalibration mechanism, usually.If it senses that the stick is in a certain position for 3 seconds, it'll recenter the stick on that point. This is important, because heat and humidity can affect what forces the force sensing resistor sees.The biggest cause of TrackPoint drift, is usually preceded by the pointer STOPPING movement. Then, when you let go, it shoots across the screen, then stops. This happens when you hold the stick in the same position. So it thinks it needs to recalibrate, and it does.
But then you release, and it realizes it went out of calibration AGAIN, and that's when it stops. The cure for this is to make it so you can cross the screen in 3 seconds, preferably less, by increasing TrackPoint sensitivity and pointer speed.The other cause is a defective TrackPoint - the self-centering mechanism doesn't work, or some other problem. If the first solution doesn't work, call IBM and tell them that the TrackPoint drifts randomly. They should send you a new keyboard.As for Enhance Pointer Precision.
That theoretically could help if you're right on the borderline of that 3 second mark, because a hard hit on the TrackPoint will cause it to bounce back a little if you have it on, causing you to have to go further. However, with that function off, I find using a TrackPoint (or another pointing stick without the inertial features) is like sliding on ice.
Lenovo Touchpad Cursor Jumps Around
I am new to the forum, and I have 2 questions.1. I was all set to purchase a ThinkPad Edge on Sunday and the more and more I used the store display machine, I backed away. About 10% of the time I went to click on a link, the cursor would not activate the link and simply move up about 1/4' on the screen. When I redid it, everything was fine. It seemed when I used the cursor continually, this was not an issue. But if I let it sit a few seconds / couple of minutes, the problem would recur.
Is this a known problem on this machine? It really turned me off.2. The machine I am looking at is i3 processor / 4 GB Ram / 500 GB hard drive / Win 7 Professional version / bluetooth / LED display with no blueray and no special graphics card. The price is $675.00 new. Does anyone have an opinion of this value. Why do some on this forum say it is not really a thinkpad?Thank you.
