Touchpad blues: Pointer jumps, moves erratically on new Latitude D620
Hi,
I've turned off my touchpad because the pointer is so wildly unstable, but I prefer using a touchpad to a trackpoint/stick. Any tips on what to do? Dell, are you ever going to provide a touchpad driver that can make this thing work properly? Thanks!

I can't seem to find this "inertia" setting. Where is that? I disabled the "assume there's a mouse wheel" setting on the ALPS device itself, and disabled the pointing stick & buttons too.

Well, I spoke too soon, and my happiness with turning off the inertial movement thing didn't last long, and that setting didn't help much. However! I did get a lot more relief from turning off something called "Fast Initialization" in the mouse settings. Changing this setting also decreased the number of tabs and options available in the mouse settings control panel, so now I can't tell you where the inertial movement option was. I suggest you skip to opton B, below, but if you want to keep hunting for inertial movement, I *think* it was here:
Option A: Inertial movement (maybe): Control Panel-->Mouse-->Pointer Settings tab. I also turned off "Enhance Pointer Precision" there. If Inertial movement is not on that tab, look for the tab that has a mock up of the touchpad with yellow right angles in each of the corners--I think it may have been there.
But here's the better solution (although it won't get you the touchpad of your dreams, unfortunately, or I should say, the touchpad we paid for):
Option B: Turn off Fast Initialization:
Control Panel-->Mouse-->Hardware tab-->click on Alps touchpad in Hardware tab->Properties-->Advanced Properties Tab. In that window, make sure Fast Initialization is *not* checked. You might also use the Help button (?) to get advice on increasing or decreasing the other two options. I now have mine set to 200 sample length and buffer rate of 300. OK your way out of there. I think you may have to restart after this, but Windows will tell you.
I hope this helps! Please post if you find something even better!

I'm not sure I followed what you say about the plastic bag, but I'm pasting in what is, I think, the relevant posting from another thread. I think the person suggests using the plastic bag, not as a fix, but as a way to quickly re-create the root problem--electrostatic build-up. Here goes:
"The Crazy Mouse effect seems to be an electrostatic problem.
I tried the following with a Dell Latitude C510 (Synaptics Touchpad V5.7) Driver v7.0.. BIOS A12
Rub the laptops palmrest with a plastic bag. The housing gets charged with electrostatic energy. When the electrostatic energy reaches a certain level the mouse starts going wild. Then discharge the laptops surface by groundig it (One Hand on the surface of the Laptop, the other on electrical ground (PE) after a few seconds (bodyresistance slows the process down) the pad works fine. I tried this with all our Latitudes (8 pcs.) and it worked the same way. I assume that by typing on the keyboard the housing gets charged after a while, and then the effect takes place.
Please try that and tell me if it worked for you.

The cause of the erratic function, I can not tell you, but the tape did fix it.
