Luvmydell,

I'm heavy handed so I have to turn off laptop touchpads and use an external wireless mouse, otherwise the cursor jumps all over the place when I'm typing.  Specifically, I've seen this problem occur on a Lenovo laptop that had one of those little joystick thingies between the G and H keys.  It turned out that the pressure-sensitive foam assembly under the joystick was pressing down on a small cable underneath it.  I loosened the center keyboard screw on the bottom of the case and the problem went away.  Might be something similar on the 1525's touchpad assembly.

Sometimes the pad sensitivity can be adjusted to minimize the problem, which is caused by dangling fingers when typing. A better solution is the free utility TOUCHFREEZE. This free program shuts down the pad when you begin typing.

Not an answer I know but I've got a similar problem on my 1011 but only when typing online, no problem with other applications but a nightmare when keying in log on details and passwords etc ( or typing in online forums !) I'm convinced the problem is not related to the touchpad as I now type with extreme caution and have seen the cursor jump off line ( and sometimes off screen) for no reason. I've logged the problem on this forum but so far no answers. I've also sought help on the Computeractive forum but again without success, although someone did suggest that it might be browser related so I tried Chrome instead of IE9 but the problem remains. If I get to the bottom of it I'll get in touch and I'd be grateful if you would let me know how things go at your end.

I uninstalled the keyboard and allowed it to reinstall itself in the shutdown and it seems to be working well....try it!

I have gone so far as to uninstall the keyboard and allow it to reinstall itself and it worked temporarily now same old thing!

I uninstalled the keyboard and allowed the system to reinstall it as a plug and play if you will and it seems to be working fine....try it!

I tried something...I uninstalled the keyboard from the system and allowed the system to reinstall it and I thought that would work and doesn't seem to be helping

I downloaded the touchpad driver from the Dell website and installed it - early days but so far so good !

I will try that and see what happens. 

Been a few days now and have not had any problems since I installed the new driver.
