My launch LCD Steam Deck is unfortunately now afflicted with a power button issue. It amounts to the power button being unresponsive ~9 times out of 10 (and getting worse). It has been reported on, but has no definitive fix as far as I can tell.

My fixes attempt so far have been:

• Squirt isopropyl alcohol (also contact cleaner later on) from the outside (suggested in [https://www.reddit.com/r/SteamDeck/comments/vlv3px/psa_how_i_fixed_my_steam_decks_unresponsive_power/]) : no perceptible change.
• Open up the casing and try pushing the board back into a better position (as a proposed fix in [https://www.youtube.com/watch?v=123jykFjF50]) : felt like an improvement, but did not stick for very long.
• Mostly I have been working around the issue by using the wake on Bluetooth feature from the SteamOS preview channel and using a Switch Pro controller (because it’s not BLE) or a headset. This has been pretty reliable but for obvious reasons this is not ideal (and also will not work after a shutdown).

Did someone try a lasting fix for the issue without soldering ? Maybe putting a piece of plastic or electrical tape between the button and the switch helps (like in [https://www.youtube.com/watch?v=JhwThw6Ke-U]) ?

Edit 26/04/2025: I put a piece of electric tape between the button and the switch. and there is a very tangible improvement. Not every button press works but most of them do so far. I’ll see about the longevity of this fix.
