Try this one

Didn't give an image, man. It resets a few times and then pulls off at 1.23A. and the next time I want to turn it on, it takes 30-40 seconds. When I turn it on, it pulls 1.23A and closes again.

I got an image. There are only a few problems.

When the device displays an image, it displays as "manufacturing mode on alt + F".

When I switch to normal mode with Alt + F, the image disappears and does not return.

When I enter and save the "service tag" information by logging into the bios, it does not display any more and it turns off after a few seconds, pulling around 1.10A.
