Can I install a video card chip if there is space?

Question

Iron

There is a soldered place for the video chip and two RAM chips for the video chip. If a BGA chip is soldered to this place, will it be a normal phenomenon, or an experiment on a laptop?
HP 15-ba102ur has an A9 with Radeon R5 Graphics, and I want to install a Mobility Radeon R5 M230 there. There is a groove under it. Does it make sense to do this?

Answer 1

Experiment, you still need to find out the necessary harness and find the right BIOS.
Alternatively, look for a photo of the factory laptop board with the chip already installed and look for differences.
Plus you need to look for a new cooling system.
My prediction: 90% brick

Answer 2

I think it can be done, but is it advisable?
1. BIOS firmware for boards with discrete graphics and UMA may differ.
2. The cooling system for boards with discrete graphics and UMA differs at least in the area soldered to the heat pipe above the graphics chip. Can you solder yourself? Or will you order?
3. It will be almost impossible to remake the board without a schematic and boardview. The board is fresh, so far I haven’t seen the schematics.
4. You need a video chip and video memory, for which the board and bios firmware are designed.
5. It is necessary to restore the power supply system of the video chip and video memory.
6. Most likely it will be necessary to solder the resistors / assemblies so that the image comes from a discrete chip, and not from the processor, but it happens differently here.
7. You may need to solder pull-up resistors ("straps"), which will tell the board controllers that the board is now with a discrete chip.
Usually, the reverse operation is carried out with the boards, namely, the faulty discrete video chip is turned off. Instead of implanting a chip on the board, I would buy an external adapter minipci-e / ngff to pci-e x16 to connect an external video card, where I would install something like 1050/1060.

Answer 3

Theoretically possible, practically not.
It is not enough to solder only the chips and reflash the BIOS, you still need to solder a bunch of piping, often in the form factor 0603/0402 or even less, which is quite hemorrhoids and non-budgetary for work + you need to find all these details.
In general, buying a new motherboard will be unspeakably more profitable than such an excision.
Chips are not installed not because of the cheapening of laptops, but because of the cheaper production of boards. A trace is made for the series and a large batch of PCBs is ordered, because all the same, these are templates, masks, electrical control cards, etc. Then, only those parts that are planned for this model are placed on the machine.
