Solved! Lenovo laptop black screen

Dec 17, 2020
I have a lenovo yoga 300 ibr 80M1 runnning Windows 10. It dows turn on, but only shows a black screen, not even the lenovo logo shows up.
I need to turn it on and off several times before I can actually get a working screen (once I can get the screen to show the lenovo logo it can open Windows quite fast).
I've upgraded all drivers and even tried restoring windows 10 to factory settings to no avail.
