For anyone who has a similar issue like me, it turned out the nvme ssd i was using didn't agree with the notebook when it came to sleep states. I swapped it with an WD Blue SN570 and now everything works as expected.

After letting the Laptop rest for a few days, the cam was back shortly, went away after a few seconds though.

Would love to daily-drive this laptop, but i kinda need a webcam to do that

@Momo-0 I tested both Pins with and without the LCD cable attached, but I get no connectivity between them and ground. No beeping

@george is there any chance i could get a replacement screen/camera?

@George any idea what else I can try? I see no reason the camera would be damaged, im pretty careful around my stuff

@George tried and older image with kernel 5, and tried to unseat and clan the cable of the monitor with 99% alcohol, still no video device

image is 20241004-ubuntu-24.04-preinstalled-desktop-arm64-laptop-v20

kernel 6.1.75, i have no video0 device under /dev/ and cheese for example doesn't show a webcam either, any idea?

@george that did it, wireguard works now, thanks

@george sudo modprobe wireguard gives me:
"modprobe: FATAL: Module wireguard not found in directory /lib/modules/6.1.75"
