Do you have multitouch gestures?

I believe your touchpad can be improved like HP840 G3 with VoodooSMBUS/VoodooRMI

@PrabhuR Sincerely, I didn't test it and I will not test it in that machine.

On the other hand, I tried to boot my internal win10 (on another pc) through external hard drive with opencore. The result is a continuous bootloop from the very beginning.

I suppose this behaviour is related to the way opencore treats windows: as a bootcamp partition. I will not modify my internal windows partition so I will try to do this (and I recommend you to do the same): create a partition on the external hard drive suitable for your windows partition, clone the internal win10 partition to the external (using CCC, for example) and follow the dortania guide about multiboot (chameleon, stolen and rebranded) systems. Then, try to boot the external win10 partition using opencore. 


I hope I explained it properly and sufficiently clear. I hope..

I have exact the same laptop, everything works but I can't seem to get the intel 620 to work.

Any advice? It keeps saying 4mb in device properties.

Thanks in advance.

Did you set your BIOS accordingly?

In the BIOS, under Built-In Device Options

Set Video memory size = 64MB
