Chosen Solution
OK so I was having your typical Xbox experience of it being really screwy and Spotify was crashing and doing all sorts of things and I was having a bad day, so I went over and unplugged my Xbox and kinda hit it like a dumbass, it didn’t get damaged on the exterior and after taking it apart all seems good, but now it just doesn’t turn on. Whenever I plug a USB in it works fine but when I press the button it chimes, am the light turns on, then immediately off. All the resets don’t work, like unplugging it for 10s or holding down the eject and sync buttons.
My guess would be power supply failed. If you do have a spare laptop drive lying around (2.5”) you can test that on the Xbox and see if it stays on and not shut off immediately.
