Hello. the title might be a bit strange, but thiss is a passion project. Something more similar to what Dosdoode1 does on youtube than regular repair.
As much as Dosdoode hates planed obsolecense on mack boards i have something against garbage tier hp products, so i rescured some to experiment on. I have already discovered an "easy way" to put both sata and nvme ssd's on hp stream 14 ax motherboards, replaced cpu from celeron to pentium and published my successes on few repair forums so people could fix those boards when emmc chip dies. but now i would like to do the same for cb series of motherboards, and i need to ask if anybody know where id resistor jumpers are on this board?
For ax series the matter is easy, there is outdated board view and documentation for brasswell quanta 0p9 board
sadly cb boards are not that well documented, they run gemini lake cpu's like celeron n4000 and possibly pentium silver n5000 (the same bga package and most specs) and similarly to ax series sata m.2 socket remain unpopulated on the board pcb so enabling it to work should be as simple as on ax board, by populating 1 connector and 4 capacitors. But to select between emmc and sata storage controllers i still need to find the id2 jumper resistor equivalent on cb motherboard .
I am doing that mostly for fun , because the board i haveis "technically" supported by windows 11. has enough ram, virtualisation, tpm and supported cpu, but onboard storage is only 32gb, so there is not enough space for anything.
I don't know why hp even released this kind of a laptop in 2019, especially since motherboard was designed to handle normal storage, 4 core cpus and more ram.
So the question is, did anyone ever tryed to locate id resistor jumpers on one of those boards?
