Funnily enough, this is the first thing I suspected, given that it's happened to me (under Ubuntu in my case).
Although even if experience didn't lead you to suspect a software issue, I would have expected one of the first diagnostics given these symptoms to be to shine a bright light into the screen to see if there was anything being displayed. Jumping to replacing logic boards is just clutching at straws.
- karmakaze 7y agoThis has happened to me multiple times because I use an external monitor mirrored with the laptop display dimmed to zero because there is no 'don't use this display' setting for it. The first time or two I hard power-cycled it, because by the time I have the laptop at another location I've forgotten the context where it was last used. Then I realized it's just the brightness.
