Cypress Touchpad Driver issue and suggestion in Lenovo IdeaPad Z480

I just purchashed Lenovo Z480 recently and I installed it with Windows 7 ultimate 64 bit.

 

The touchpad driver I got is from Cypress, not synaptic. I had used Synaptic Touchpad driver before with another laptop. I found out the Cypress driver lacks of many features found in Synaptic such as:

 

1. No two-finger tap feature to simulate middle mouse button click (this is the most dissapointing).


2. No one-finger horizontal/vertical scroll region feature (see this screenshot).

 

3. No three-finger tap feature to simulate context menu (right click).


4. No speed setting for 2-finger scroll up/down feature. The current speed is a bit too high for me.


5. Default Tap sensitivity is too low. I had to tap hard just to perform single click. Fortunately, this can be fixed by setting Palm Sensitivity to the lowest Light setting (from Control Panel -> All Control Panel Items -> Mouse -> Cypress TrackPad -> "Click to Change Cypress Trackpad Settings" link  -> Palm Rejection).

 

 

I had tried installing generic Synaptic driver, but it seems it is not compatible with the laptop. Most features in Synaptic don't work, the setting in Control Panel -> Mouse -> Synaptic doesn't show anything except basic left/right button settings. Only the one-finger horizontal/vertical scroll region worked.

 

 

My questions:

1. Why the synaptic driver doesn't work with my Z480? Is it because the touchpad hardware is only compatible with the Cypress driver?

2. Is there a way to use Synaptic touchpad driver with the full features enabled?

 

 

Suggestions to lenovo and cypress:

Please add the features that missing above for the Cypress touchpad driver, e.g.: two-finger tap for middle click, three-finger tap for context menu, one-finger scroll region, speed scroll settings, etc.

 

 

Currently I'm using Cypress Driver v2.3.7.30 that I downloaded from Lenovo site.

Hi lenovo staff,

 

I checked in lenovo Z480 driver download page, for windows 8, the driver only contains Synaptics Touchpad Driver. If the user has Cypress touchpad, what would happened if we run the driver installer?

Re: Cypress Touchpad Driver issue and suggestion in Lenovo IdeaPad Z480

Hi RMattoo,

I tried and it happened to be the same latest version driver (2.3.7.25) that I had installed. So nothing changed at all.

Honestly, I'm dissapointed that lenovo provide Cypress touchpad for the Z480 besides Synaptics. The problem is both of them have very different feature comparisons where the cypress is the suckest one, it lacks of many features that synaptic has. And I'm happened to be an unlucky to have cypress in my Z480. I observed that It seems all of blue color Z480 with intel core i5 has cypress touchpad, where the red one has synaptic. If I knew that, I will choose the red one instead.

Suggestion to lenovo:

Please don't use cypress touchpad for all of your products!!! (until they can provide features equal to synaptics)
