Acer Aspire 5 A515-52G - Touchpad compatibility under older OS'

da_someone

• So I've got an Acer Aspire A515-52G Laptop and I'm currently trying to main Windows 7 on it (It's a 2018 UEFI Class 3 Laptop (It has no Legacy/CSM)). I've successfully installed Windows 7 on it using 3rd party tools (UefiSeven) and the only driver that's missing is the touchpad. It's a "Precision Touchpad" which some people reffer to as the "Advanced" option is the BIOS. Sadly, my BIOS is very locked /doesn't have many options in it, which makes me mad because I can't get "Legacy OS' " to recognise my touchpad (It's the last thing I need to finally main Win7). The touchpad works on NT10.0 (Windows 10 and higher) ONLY, and on older OS' it's simply not being detected (It's not listed under Mices / HID Devices, even after enabling "View hidden devices" option). My laptop has an older brother Acer Aspire 5 A515-51G which has full unofficial support for Windows 7. These two are very similar to each other which got me thinking; can I possibly REPLACE THE WHOLE TOUCHPAD MODULE with the A515-51G one to make it compatible with older versions of Windows? Will the option to switch between Basic/Advanced touchpad appear in my BIOS or would I have to create a custom one? If it's not possible to replace it with this model, what touchpad can I replace it with to make it work under Windows 7? The price doesn't make a difference for me. I simply want to use Windows 7. Please, don't change this into a "Upgrade to Windows 10 because Windows 7 is out of support" thread. Thanks!

Hi! When you press CTRL+S in the main bios tab, an option called touchpad appears?

No. This option was removed after A515-51G. The only useful features my BIOS offers is switching Optane without RAID to AHCI and changing the date.

I just want to know what touchpad I could put in my laptop that'd be compatible with win7...

I don't know which touchpads are compatible with windows 7. However, copy and paste the idhardware of the touchpad here as maybe there is some driver compatible with windows 7 on google:

I can try, but I'm 99% sure that it won't work. The touchpad itself doesn't require drivers, it requires Intel IO drivers to communicate with Windows, and because Acer has put a software lock on the touchpad I have, getting Windows versions older than 10 to even detect it is impossible. Many laptop manufacturers and Intel have instilled this incompatibility deliberately of course, to prevent or at least make unpalatable using Win7 on the newer boards above Gen8. Their viewpoint is that most laptop users will not want a laptop without touchpad utility. They're correct, but that's not going to stop me. I'll order A515-51G's touchpad. I'm sure that it'll work under Windows 10, but 90% sure it'll require a bios mod to work under Windows 7. I'll come back to this post in a month and tell you how it went.

And by the way, my touchpad isn't detected as a standard mice, it's listed under HID devices as HID Compliant Touchpad.

That's why I would like to know the device's idhardware.
