Cooler Master booting (maybe?) issue

Last year I upgraded the mainboard and RAM from my first batch Framework 13. I took the original 11th gen board and RAM and got a Cooler Master case and put Linux Mint on it and when it runs, it runs perfectly. The problem is that whenever it does shut down, either intentionally or unintentionally, I have an amazingly hard time getting it started again. The power button on the case is spongy and it is hard to tell if you really hit the button on the mainboard. There never seems to be any kind of immediate reaction, so I always wait a few seconds and sometimes something will happen to the lights on the board. This most recent episode they have switched from two green lights on solid to just a white light on the right side of the board, which is where the power is connected. Sometimes I hear the fans spin up and sometimes I don’t, but I don’t get any video output.

From past experience, I know that if I keep fiddling with it, taking the cover off and back on, plugging it in and unplugging it…eventually I will get it back on and everything will work perfectly again for a few weeks. But I’d really like to figure out how to avoid the day or two of fiddling each time it turns off.

I know I am running Linux Mint currently, but I had the exact same issues when I ran Windows 11 for a few weeks on the same hardware setup, so I hope it is OK that I am posting in this forum.

More people need to know about the 10x press of the Chassis Intrusion Sensor to enable Stand-Alone Mode from this thread, I’ve still not found it in the Knowledgebase.

Good luck!

Thank you! You are right, I had not come across that one before. I definitely enabled Stand Alone mode before, but I have read in another thread that perhaps a certain number of failed boots enables secure boot again?

I do have some more basic questions though, like when the computer is off and I press the power button on the case, what should happen? Like, should I get an immediate response from the LEDs on the board? Frustrating to never know if the button on the case successfully made contact with the button on the board.
