I have the HP Slim Quad 100 Notebook with the HP Synaptics Touchpad.

 

The touchpad intermittently stops working correctly.  Sometimes it's so bad that it's unusable. 

 

I have done a little research and I found that the driver is causing the Touchpad to detect clicks and touch when there is none.  I've confirmed this by looking at the real-time Pressure graph tool that measures Touch Pressure.

 

According to the Synaptics Pressure Graph tool (in the Synaptics folder, the red "Z" Icon [SynZMetr] is the name), the Touchpad is detecting pressure even when my hand is off the Touchpad altogether.  I suggest that anyone with this same issue confirm this themselves as well, during your time of random malfunction and sporadic movements.  You will see pressure in the pressure graph even when there is no contact with the touchpad.

 

My temporary solution:

 

Double click on the 'Reflash' folder in the Synaptics folder:

 

C:\Program Files\Synaptics\SynTP\SynReflash

 

After I reflash using this method, the issue is fixed immediately.  However, sometimes I have to do this on a daily basis!!!  What is the root issue and how can I fix it???

----------------------------------------------------------------------

 

Other Troubleshooting:

 

I've reinstalled the newest driver a few times:

 

Current Version:

Synaptics Touchpad Driver -18.1.7.8 , Size: 187.8 MB  --  Oct 11, 2014

 

File name: sp66500.exe

 

^ This did nothing to solve the problem from re-occurring.
