Fixing crashed OS

Fixing this for a chess friend whose Windows OS has crashed. It’s a dual boot machine so it has both Apple Max OS as well as Microsoft Windows. Previously Windows crashed (no surprise ) so only the Apple OS was usable. Now at the dual boot screen it is only black.

I tried starting it up and all I see is a black screen.

That’s my own mac side by side the “black screen” Mac. They look identical.

Restored in less than 5 minutes. Apparently the brightness was set all the way down to zero hence the black screen.

So the Apple OS was not at fault. It was working all the time

I will still need to fix the Windows crash which will take more time and involve reformatting the Windows partition. I still feel the Air is one of the best notebook for a chess player for it’s mobility. I fully recommend it to any chess player particularly now that the new models can run up to 12 hours. The starting price for a brand new Air is around RM 2999.
