yoltboy01 Posted September 26, 2020 Share Posted September 26, 2020 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!

Thanks for any help you can give! i'm joining this conversation, i too have 8th gen laptop. I successfuly downgraded to Windows 8.1. Touchpad works, but two finger scroll does not. Any way to fix that problem too? (Dell inspiron 3583) Edited September 27, 2020 by Jaguarek62 Link to comment Share on other sites More sharing options...
jaclaz Posted September 27, 2020 Share Posted September 27, 2020 @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): https://msfn.org/board/topic/181673-solved-elan-ps2-touchpad-driver-for-xp/ jaclaz Link to comment Share on other sites More sharing options...

jaclaz Posted September 27, 2020 Share Posted September 27, 2020 (edited) 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 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"? Or possibly the device is not a Synaptics one? jaclaz Edited September 27, 2020 by jaclaz Link to comment Share on other sites More sharing options...

Is that what you have? 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. Link to comment Share on other sites More sharing options...

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. jaclaz Edited September 28, 2020 by jaclaz Link to comment Share on other sites More sharing options...

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?

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. jaclaz 1 Link to comment Share on other sites More sharing options...
