I have tried double clicking the on off feature as described in the user manual for my probook 4520 because of problems caused by its oversenitivity. I've searched the internet for suggestions to solve the problem and naturally have been using a mouse to navigate. Does anyone have any helpful suggestions on how I may be able to disable the touchpad so that I may type on my touchpad without having the touchpad interfere with my typing?

Join the club, it seems to be on everyones complaint list.

Here's the proof.

Quote from link above:
During our testing, the touch pad exhibited some very strange behavior. At times, the cursor would jump across the screen without warning and without provocation. At other times, the movement was not quite as severe, but it still significant enough that we had to reposition the cursor before continuing on. As it turns out, the folks at HP informed us of a driver update that took care of most of the problem. The wild cursor jumps ceased altogether, but there was still some unintended cursor movement from time to time, though not nearly as often as before the update.


Any way this is the only information I could find.

Turning the TouchPad on and off


The TouchPad is turned on at the factory. When the TouchPad zone is active, the light is off.
To turn the TouchPad on and off, quickly double-tap the TouchPad off indicator


Here is the support page for this probook 4520.

The only drivers I see available are for linux, if thats what your using for an OS, here's the drivers page.

Synaptics TouchPad Driver for Linux (2.6.32 Kernel)

Please let me know if this worked or not, because I have basically pulled this information off of the web, but can not test its accuracy.
