Well the drivers from lenovo site, are I2C (Intel) drivers compatible with Win 7 !
The problem, is that the touchpad driver seems to have a need of resources greater than "default 1000".

The IRQ vector on which the I2C controller is number 17 for me,
the allocation address can vary,
xFE035000 to xFE035FFF, but sometimes when I reinstall it :
xFE034000 to xFE034FFF
The vector length is alway 1000, but needed to increase for touchpad to work.
I have notice that when the controller is disbaled in device manager: The "AllocConfig" key (I gave previously) -- disappears.
At reg address "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_8086&DEV_9D61&SUBSYS_14E01043&REV_21\3&11583659&0&A9\Control"

Only a "FilteredConfigVector" named key remains (that's a REG_RESOURCE_REQUIEREMENT_LIST)
The binary:

"FilteredConfigVector"=hex(a):88,00,00,00,05,00,00,00,00,00,00,00,35,00,00,00,\
  00,00,00,00,00,00,00,00,00,00,00,00,01,00,00,00,01,00,01,00,03,00,00,00,00,\
  03,01,00,80,00,00,00,00,10,00,00,00,10,00,00,00,00,00,00,00,00,00,00,ff,ff,\
  ff,ff,ff,ff,ff,ff,00,81,01,00,00,00,00,00,01,00,00,00,00,00,00,00,00,00,00,\
  00,00,00,00,00,00,00,00,00,00,00,00,00,00,02,03,00,00,00,00,00,00,00,00,00,\
  ff,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00
 

And it defines the resource allocation size when controller is activated:


To allow more resources for the touchpad to work (for me it's because of code 12 not enough resources...) I'd change permission of that key to enable edition of the binary and change the mem alloc to 3000 or so...

So I identified the right bits to change to make the memory alloc greater:

I replaced first bold marked bits by
30,00,00 instead of 10,00,00

and second by
00,01,00 instead of 10,00,00

So the length is extended by X3 and alignement is made a bit higher
I now need to activate the controller again to see if it will work

It looks like that now


EDIT: When I re-activated the I2C controller everything went as I changed nothing,
Length and alignement are reset to x1000... However there's a "BasicConfigVector key" in "LogConf" just under registry that looks similar to "FilteredConfigVector". I would like to change it too,
but it doesn't let me change the value nor edit the permissions...
EDIT2 : thanks to google (take-ownership-of-a-registry-key-and-change-permissions) I now could edit binaries of "LogConf" and "control". Changed both "BasicConfigVector" and "FilteredConfigVector" Keys. Set length and alignment to 0x10000 But values are reset when I activate the controller... This must be hard-coded in the Intel driver itself...
A way to make it work would be installing a very basic touchpad driver that requires only few resources (not compatible with smart-gesture ) But this would only work with a different hardware component touchpad...
Edit 2,5 : I tried to change to a static adress, but it is still resetting as soon as we activate the I2C controller... What Ima try will be: to activate the controller manually from registry and powershell

After more thinking, maybe this "Resource approach" is futile because these Touchpad drivers are used to contacting a Touchpad device directly and not through some stupid I2C bus. Because, I tried force assigning even the basic PS/2 mouse driver to this device, and still not enough resources! :P So, try to directly contact a touchpad maker and request a driver that can talk through the I2C bus to a Touchpad device behind the I2C controller. If they are kind and maybe already have such a driver, probably they would provide it to you.

Also: if you're a Windows programmer, maybe you can port the OpenSource ELAN I2C touchpad drivers from a modern Linux (such as Linux Mint 19.3) to Windows 7. These touchpads are working flawlessly at Linux and all the sources are open. It may be tricky to port because of the differences between Windows and Linux, but definitely doable!

Hi everyone I just buy a new asus laptop in 2019 it come whit windows 10 and after six month (THIS TRASH GET ME MADDDDD (STUPID UI))after that i try to install windows 7 and after 1 year seeking i cant enable touchpad (igpu and other drivers modification succeed ) till i found this forum 3 month ago
after realize the problem try to install another os (win 8.1 and linux(chalet and mint) and etc) it works fine just in 7 not works
i found a way to fix this (i think it should be works) is there any way to merge windows 7 and linux (not vm) like linux be windows 7 subbase (as linux is open source) (linux for supports and drivers )(windows for ui and other) replace linux ui with windows 7
(i cant do this by my self) sorry for bad english

Just use Win 8.1 and move on.

I've worked really hard with @canonkong to try to get it working on Win7, but failed.

Thank Microsoft for that, they are responsible for this insanity, for no good reason:
GPIO -> I2C -> HID/Touchpad

There is nothing wrong with simply using PS/2, except for preventing laptop users from using older OSes.

How are you guys?
I still have my asus 7 gen laptop with the broken touchpad.
From time to time I check this thread, I like to think someday someone will find the way ;)

Curse you I2C ;)

Still, it's nice to see there are some people that still care about windows 7

I had this exact same problem, on Windows Server 2022 based on Windows 10. I fixed it by force installing the hidi2c.sys "I2C HID Device" driver from a normal Windows 10 Install and it worked. After installing it I installed ELAN touchpad drivers normally and it worked. Maybe, it can be working on Windows 7 too if someone can port the driver.
