Touchpad Driver on Intel 8th Generation Notebook

Recommended Posts

Hey Windows 7 Community!

2 years ago I bought a new notebook, which obviously had Windows 10 (1709?) preinstalled. I successfuly downgraded it to Windows 8.1 already. By modifiying the Intel UHD 620 Drivers, I got all drivers working on 8.1

However, when I tried to install Windows 7, the Touchpad (PTP-) Drivers were not working and I always have to connect a mouse. I'm wondering why the touchpad works with 8.1 and if the driver can be modified to use it on Windows 7 as well. My device is the ASUS VivoBook S15 (R520UF-BQ385T).

 

Thanks for any help you can give!

@yoltboy01

The ASUS Vivobook S15 has not a touchpad, it has a sort of secundary touchscreen, so-called "screenpad 2.0".

Is that what you have?

@Jaguarek62

Other more "normal" laptops have touchpads that are usually either ELAN or Synaptics, these - generally speaking - have been around since a lot of time and usually suitable drivers/configuration tools can be found for older systems.

Two finger scroll is typically something that is set by the configuration tool in the Registry and that the driver reads

Post the EXACT make/model of your laptop and - possibly - also the device VEN/PID.

If the thingy is ELAN, we already have a thread where we "dissected" the settings (to achieve XP compatibility, but the settings are OS independent):

The VEN_DLL is seemingly used by some Synaptics? devices (on DELLs).

The actual DEV_08CA I cannot find much about.

That laptop seems to be using (on Windows 10) the "Driver Intel HID Event Filter" which - whatever it is - doen't seem like a hardware touchpad driver.

Versions of this driver can be found for 8.1, but they are probably only a part of the story, the Windows 10 must be using a "generic" driver, the Windows 10 one should be:

https://drivers.softpedia.com/dyn-search.php?search_term=dell+synaptics&p_sortby=0&p_category=7&p_picks=&p_license=&p_lastupdate=0&p_whatos=0

https://drivers.softpedia.com/get/KEYBOARD-and-MOUSE/Synaptics/Dell-Synaptics-Touchpad-Driver-1921736-for-Windows-10-64-bit.shtml

which is a "complex named" .cab, (and not the usual installer) which should mean it comes from Windows Update or similar but the 08CA is not in the SynPD.inf :w00t:

Do you have the driver that was used on your Windows 10 install?

You will need to check the SynPD.inf of the 8.1 drivers you can find here:
http://dellwindowsreinstallationguide.com/dell-touchpad-drivers/

if there is no 08CA entry in the .inf, maybe it is possible to add one, but without a "reference" working Windows 10 driver, under which "group"? :unsure:

Or possibly the device is not a Synaptics one?

You havent googled the device number. My S15 does have a normal touchpad and not a screenpad 2.0... In W8.1 the touchpad works after letting Driver Booster install all drivers but in W7 it doesnt work.

No I haven't, I asked you instead, as I had a doubt.

Now, can you provide the VEN and DEV?

And also, if you have a reference for them which drivers are working for you in 8.1.

Thank you for your informations. I actually did pretty random thing and installed elan driver (despite tha laptop having synaptics touchpad). And the scrolling started working and I have configuration utility for more gestures. So if anyone has simmilar problem, you can try to install random drivers I guess? :D

Yes and no, Dell is Dell, it is very possible (actually probable) that your touchpad is actually an Elan one and I thought wrongly that it was a Synaptics one.

Then I wonder, why the hell did they not list it on their website?

...because Dell is Dell, they simply have their own ways to do things AND mis-documenting the *whatever* they do, not necessarily worse (nor better) than any other OEM/laptop manufacturer, only *somehow* different.
