touchpad option on control panel is gone

[medic01]

The scroll option on my touchpad just up and disappeared yesterday.  I went to the control panel to adjust it and it and could not find either a mouse option or touchpad option with scrolling.  Do I need to install new drivers?  I have an hp pavilion dv4 with windows 7.  Thanks

Hi,
 
Can you post back with the following.
 
1.  The full Model No. and Product No. of your dv4 series notebook ( from the service tag underneath your notebook ) - see Here for a further explanation.
 
2.  The full version of the operating system you are using ( ie Windows 7 32bit ).

Hi,

Open windows Control Panel, open Programs and Features and let the list populate.  Let me know which of the following entries is listed.

Synaptics Pointing Device Driver

ALPS Pointing Device Driver

Hi,

Ok, try downloading and install the ALPS driver on the link below.

After the installation has completed, restart the notebook.
