Lenovo legion 5 pro black screen after windows update

Lenovo Legion 5 pro laptop

Dualbooting ubuntu and win 10

 

Yesterday evening i was using the laptop on win 10 as usual.

The laptop worked with no problems.

After that i pressed update&shutdown and went to sleep.

 

Next morning:

After turning it on it's completely silent (no fan speed) and has a black screen. It's unresponsive to keyboard shortcuts or getting into bios.

Somehow i managed to get to grub once, so i know that the kb and display work.

After selecting windows in grub it went back to a black screen.

 

I can't manage to get back into grub to try to see if ubuntu works.

 

Things I have tried:

- turning off by holding the power button and then turning it on after some time

- opening it, removing the battery, powercycling it, turning it back on

- windows + ctrl + shift + b

- spamming every key possible to get into bios

 

Also noticed the day before the problem that the time and date in windows were off and had to fix them

I have now also reseated the ram, problem still not fixed.
