Hello,

The backstory (maybe some info could be useful):
Recently I noticed that my ACER tablet wasn't very effective and was running kinda slow. I tried everything to make it faster, but nothing has worked. I thought that maybe installing a lighter OS would solve the problem.
Sadly, when partitioning, I formatted the EFI partition and I couldn't get any OS I tried installing to boot right. I decided that was the time to go back to Windows 10, and it actually restored my EFI partition, which was great for me.

In the meantime I updated BIOS from v1.09 to v.1.10, but I had to get the update file from a forum outside of the ACER website (because on producent's site BIOS update couldn't be downloaded)

What's the actual problem:
I noticed performance issues just as bad as they were earlier, and so I decided to try to install Alpine Linux, but this time without formatting EFI partition. All went good, but I encountered a problem - WLAN didn't work! I noticed earlier that for some reason Windows couldn't connect to any Wi-Fi, but appearently updating BIOS must've broken my Wi-Fi drivers. I tried diagnosing the issue on Live Alpine USB (Windows was gone at the time) but I couldn't do anything.
Now I've found WLAN drivers on the website, but Windows cannot be installed. When I try to install it from Live USB Stick, it shows me a bluescreen with info about ACPI BIOS Error.

At this point, the best solution I can come up with is to reset my BIOS to factory settings as well as all my drivers. I tried to "Load Setup Defaults" in BIOS, but I couldn't find a way to install the drivers, as well as diagnosing the issue with ACPI.

Btw I'd apprecieate a fast answer as to how do I fix this tablet.
The best way would be to not open the hardware, but to do something with the software. I am not scared of removing everything on this device, I just want it to work again with all of its components, especially Wi-Fi
