Re: acer 5620 touchpad
Hi Charlie, You can alter the touch sensitivity of the touchpad. Just go to Control Panel > Mouse > click the Device Settings tab > highlight the touchpad in the list and click Settings. At the bottom of the list on the left hand side, it will say Sensitivity. Click on that and a sub menu will drop down. Click Touch Sensitivity, and you can drag the slidebar to the right for 'Heavy Touch', meaning it will be less affected by you leaning your wrists in order to type comfortably.
I am using Vista, so your set up might be different,but there will be a similar way of doing this in XP, if you just apply similar logic to it.

It is a fault with Lenovo laptops. My cursor jumps all the time, no matter what software I am using. It is NOT the 'sensitivity' of the touchpad, for my cursor jumps even when I am not typing, even if I don't touch the laptop! I can set the cursor to a certain point on a document and then, after about 30 seconds, it will just jump to another point, even if I am in another room.
If your cursor moves erratically on the screen (for example, if it jumps around the screen, moves at varying speeds, or selects items on its own), perform the following steps:
Clean the surface of the touchpad with a dry, soft cloth to remove grease, sweat, moisture, or other liquids.
Adjust the sensitivity of the touch pad:.
Click the Start button and click Control Panel.
Click Printers and Other Hardware.
When the Mouse Properties window appears, click the Pointer Options tab. (Figure 1)
Figure 1: Pointer Speed
Under Select a pointer speed:, click to move the slider bar closer to Slow.
Check to see if the touch pad still behaves erratically.
If the touchpad still caused the cursor to behave erratically, attach an external mouse to your computer and restart your computer. Use the external mouse to see if your cursor still moves erratically.
Touch Freeze will disable the touchpad when you start typing. I have not used it, but give it a try.
Also, your touchpad could be wearing out or a driver reinstall could be in order. My wifes Toshiba had a bad touchpad and the cursor would jump all over the place. I disabled it and she now uses an external mouse. No problems anymore.
