I have quite a few Chromebooks with this issue, and they are this generation or a new generation of this line of Chromebooks. The Chromebooks have no display output at all. I have tried swapping in multiple screens, and screen cables as well as batteries. What's weird is if I plug in a USB light it can turn off and on when pressing the power button which makes it seems like the Chromebook is working. Also, if I hard reset the Chromebook the light does what I would expect with a working Chromebook. I tried with a USB mouse, but it does not light up. I am starting to do some component level repair, so I am wondering would it could possible be to try are maybe replace the component. I should mention I looked at the display connector on the motherboard, and everything seems to be connected.
