Backlight stops working on surface Pro 5

Hello everyone!


I recently experienced a weird bug on my surface Pro 5:

after exiting sleeping mode, the screen backlight would stop working. At first, I thought that the screen was not turning on. When I hard restart my computer the problem disappears.

I have this problem with about 40% of the time I go out of sleeping mode.

I realized more recently that the screen was actually on but with no backlight at all (darker than if I reduce the light display to 0).

If I have a secondary screen, I can manage to play with the parameters to deactivate/ reactivate the main screen, which solves the problem.

But when I'm on the go, I cannot do that, and the only solution I found is to hard restart the computer.

I also realized that the touch screen stopped working after this bug until I restarted my computer.

Does anyone ever experienced that and maybe found a fix?

Thank you so much for your help!
