touchpad problems

[maxnik]

I have Dell Inspirion 5100 laptop. Couple weeks ago I noticed that Touchpad was not responding well. Looks like it's
lost sensitivity or something. I raised sensitivity with Synaptics software but it almost had no effect. Also it responds a little better if I use two fingers. Has anyone had a problem like that? Am I gonna end replacing the Toouchpad, or I need to clean it somehow? Thanks. :confused:

I've seen this on Dell laptops. It's a software issue, one of the Windows security patches, believe it or not.

I am having the exact same problem and I have no idea what to do about it. Do you know if Microsoft has come out with a solution or for that matter what can be done to remedy the problem?

Thank you for your help.

I also have the Inspiron 5100, and problems with the touchpad recently.
The mouse stops when I rub (finger jumps forward a little) the touchpad.
Increasing the sensitivity helps a little, but still not fixed.

Does anyone here have the same problem ?

Is this definitly a software issue caused by a Windows patch ?!

Thanks !

Does it do the same thing with a USB or PS/2 mouse plugged in?

Under Mouse Properties > General:
Location: plugged into PS/2 mouse port

Under Mouse Properties > Advanced Settings:
I decreased the Sample Rate and increased
the Input Buffer Length, which helps even more.
Now I really have to rub hard for the mouse to
get stuck/lock-up.

I don't have a USB mouse to test. If I did, and
it worked, that would not really mean this is a
hardware issue, still could be software !?

This Inspiron 5100 is less then 2 years old. I can't
imagine that the touchpad is going already. I hope
this is just a software issue. I emailed Synaptics,
so I hope for a response.

Is the problem with the synaptics touchpad exclusive to dell ? or not? my gateway uses their pad and software

Try wiping your fingertip very gently once or twice on any cloth surface (shirt, pants, etc.) when the touchpad gets erratic. Don't know why but it works for me.
