I have a couple of question about dedicated soldered on Laptop Gpus. My laptop has space for a Gpu but it's not there and I know why. But what if I were to get the same gpu gtx 940m and pit it there? Because the better models of my acer aspire use the gtx 940m so I don't see why it won't work other yha the gpu not having enough pcie lanes or something. Juat interested and seeing if it will work.

Laptop- Acer aspire e5 523 series

Hi,

Well if you want to spend the time on this.
Find the model of the motherboard (not laptop) good luck on that.
find to see what gpu it supports.
Find out if the mobo you have hasn't been stripped of components for the gpu
then good luck soldering the chip.

For me, you are beating a dead horse, especially with acer laptops. They are cheap, they don't last long.
If you do a small mistake you most likely damage the board.
Also, you could have a different BIOS that does not support adding a GPU.

I have already got the model of the mobo, its just that the better version of my laptop has a 940m so it would make seance that a 940m would work In this laptop too. I could just just the mobo with the 940m on it and just replace the motherboard itself, but that's expensive. And i think it would be interesting if I were to solder it on myself.

I'm pretty sure they use the same motherboard for thee high end models and the low end models. So I dont see why It wouldn't work.

You'll need to check for any difference in the BIOS between the two laptops. The other problem you may find is that although the mobo may be the same it doesn't mean that it's fully populated ( they tend to leave off parts that aren't being used to save a few £s) But saying that it's your laptop and if you're prepared to risk it go ahead. Just take a great deal of care soldering, use a good iron and a good solder and flux. Clean well afterwards.

They normally use the same model motherboard for multiple variations of the laptop. See if you can find an image of the version with the gpu on it and make sure there aren't any additional chips that are missing, which would be required.

Well actually, there will probably be some chokes that will have to soldered on too.

Yep, just cheeked, some chokes, bios chips is seems (I could be wrong about the bios chips)
