Hello brother, can you let me know what model of 4750G your running? May I know if you have latest Acer 4750G bios and if so can you provide me with it? Acer website has all the drivers and bios down for this model. 
My model is 4750G-2632G50Mnkk with I7-2630QM & GT540M, let me know if your's the same and if my laptop will be compatible with driver you have.

Quick update for my rare 4750G homies, I got 2.15 BIOS installed on my 4750G-2632G50Mnkk Laptop with Intel i7-2630QM GT540M
I've attached the BIOS which worked on my laptop model. You will need Windows 7 to install it. The installer (Phoenix WinFlash UEFI) does not support modern Windows 10/11.
BIOS boot time is ultra fast now compared to my old 1.x BIOS, not even enough time for me to see Acer logo. Only thing they added otherwise is switchable graphics (between Switchable and Integrated, sadly no Dedicated only option). BIOS is otherwise still lame as f*** per Acer tradition.

Probably obvious for ppl here but for clueless people like me who was looking for bios on google this might help and confirm compatiblity, especially because Acer no longer has any drivers for this laptop. Want to see more updates for this laptop, still a powerful laptop that can handle anything you throw at it (crippled by Acer)

Thanks! Should this bios be okay with like 2860Qm?

Also I'm currently on 1.19 bios, I installed Win 11 and now the PC will freeze when I select restart. Shutdown works fine. Anyone seen this?
Will newer bios fix this?

Cheers

Thanks! Was the bios modified to work specifically with the 2630QM, or should it be okay with like 2860Qm?

Hello, not sure about 2860Qm. Windows 11 freeze issue is strange. My laptop ran Windows 11 on both 1.19 and 2.15 bios version without any issues with shutdown. 
The included Pheonix BIOS installer does a hardware check maybe so worth a risk.

Okay, thanks for reply. Shutdown is okay, just "restart" freezes.
