Fix boot failure

I encountered a situation in which my Steam Deck suddenly wouldn't boot. However, it would turn on, and the fans would run extremely loudly for a few seconds, the white power light would pulse, and then it would start over. The following steps fix the problem.

  1. Power off the Steam Deck.
  2. Plug it into its original charger (and plug the charger into the wall).
  3. Press and hold the three-dot button and the volume-up button for about 10 seconds.
  4. While still holding the buttons down, unplug the charger (which can be tricky!). The power light should blink blue a few times.
  5. Release the buttons.
  6. Plug the charger back in.
  7. The Steam Deck should power up on its own (i.e., you shouldn't have to press the power button).
