[Help] Failing power button - sh.itjust.works

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/ [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 [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). This is an in-depth analysis of the problem : [https://www.youtube.com/watch?v=OAZtSyyx-ww [https://www.youtube.com/watch?v=OAZtSyyx-ww]] 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 [https://www.youtube.com/watch?v=JhwThw6Ke-U]]) ?
