Steam Deck Will Not Turn On

Regarding the power button : sometimes it will stop working even though it "clicks", because it doesnt push deep eough anymore onto the button on the MB. Inserting a small and thin piece of plastic or cardboard between the visible button and the motherboard is reported on reddit to help with this issue without going to the trouble of actually replacing the power button (along with the extensive disassembly it requires). I just did it on my unit and it seems to be a valid workaround.
