I have been having those crashes on my Steam Deck, and for a moment I though I had a faulty hardware, but contacting Valve for support illuminated me.

This kind of crash / freeze accurres usually after 15 / 30 min of gameplay, but it can also happen right when you start your game. The game freeze; black screen; then the last frame of the game is back, and the audio stills playing.

Since I moved overseas, I am using an adapter + power strip to charge my Steam Deck, and because it was charging correctly, I would have never though of it being a problem.

Anyway, the power strip was faulty, so pluging the charger in the wall fixed all my problems (the adapter is working fine).

So if anyone has this problem:

  • Try and see if your Steam Deck crashes while not charging (battery mode).
  • Try different chargers and power outlets (in my case it was just the power strip, but it could also be other things).
  • Try not use extension cords or power strips

If after this you still have the problem, or if that also happens when you are not charging, than it may be because an hardware issue (perhaps the battery?).

I hope your Steam Decks are working fine, but I figured this could help someone down the line.

I also want to thank Valve’s Support, absolutely brilliant. Don’t hesitate to contact them for any issue, they are the best.

Take care everybody and have fun!

    I’ve had computer crashes from a bad outlet, glitching the power going into a USB-C dock. I suppose that the complicated protocol between my laptop and the hub leaves a lot of room for bad state to spill into the PC.

    I’m surprised that it’s also a problem coming directly off of the power brick too. The power circuitry already has to deal with instantly cutting back to running from the battery at any time anyway, so what’s the difference if it happens a millisecond after switching to wall power?
