Steam deck (LCD model) will, at no point, turn on unless plugged into charger or hooked up to the dock, regardless of how much battery is left. No response when trying to do things like booting into bios or anything else. Works perfectly fine when plugged in, docked to TV or standalone. No feedback at all, either, from buttons or trackpad haptics either when unplugged.
I’ve done a bios/firmware reset thing while plugged in and let that go for a while, following the advice of a Steam community forum (not sure whether the blinking power indicator thing is supposed to stop blinking when it’s done, but I definitely let it go for longer than the forum post was saying). Went through the process of going through and enabling the main channel OS updates as well through dev settings and updating didn’t fix it.
Have taken the backplate off and everything looks fine (I’m not an expert on mechanical things, though) and thankfully no spicy death pillow.
Any advice? At this point I’m even willing to back up anything important and do a factory reset if I have to. Also, if need be, I have a photo of the internals just in case I need to show it (again, not good with electronics on the hardware side of things).
What happens if you leave it plugged in for half an hour or more? After that, can you unplug it? Because at least for me, the dock can drain the battery (slowly) over time when the Deck is off, all the while the battery thinks it’s full. I would try keeping it on and plugged for a while, then unplug while it’s on.
Tried plugging it in directly to the charger that came with it for a while and still didn’t work. That was one thing I tried after looking up videos that didn’t help at all. Might try again considering I don’t know how long I left it plugged in.
