Acer Aspire V3-772g motherboard replacement The question is, how do I know whether it's compatible?

Hello there.

I have a 750m model in pristine condition...except for a couple of insignificant details. The GPU was fried and removed by a local laptop service center, the charging port and the keyboard both had to be replaced. I had to redently reassemble it in a hurry and, probably, dropped something metallic on the motherboard and shorted it or stabbed it with a screwdriver. Or I didn't, but it shows nothing but the black screen when I turn it on and doesn't seem to load. It just spins its fan at me.

I am, most definitely, ordering a new motherboard on aliexpress. The question is, how do I know whether it's compatible? There are 850m options and I want them. Getting a minor upgrade for a fair price and all the trouble would make everything 100% worth it. Is it a trap or just a revised version of the same motherboard?

You, guys, are my only hope.

I've had good luck with mainboards as advertised from Aliexpress vendors and concessionaires. Furthermore, some of them warehouse the mainboards stateside , especially those of your vintage. So deliveries can be less than a week. You can sometimes hit upon a vendor who has only 1 or 2 vintage boards left and is willing to part with them incredibly cheap. I got a brand new Win8x era laptop mainboard for $25 with free shipping from am Aliexpress warehouse in Kentucky. I'm using it right now in my reply running LinuxMint.🙂.
