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.
Either the battery is toast, or some component like “the chip responsible for rapidly cutting power over to the battery” is toast.
I wonder if connecting to a < 30w power supply would also result in your deck crapping out under load.

When you unplug it while on, does it immediately turn off?
-
What does it say battery percentage is when plugged in?
-
In desktop mode, what does it say battery health is?
-
Turns off immediately when unplugged and also turns on immediately on when plugged in.
-
On gaming mode, full. On desktop mode, 96% not charging despite showing charging icon on battery icon.
-
100% battery health.
Honestly I think you’ll have to get it RMA’d.

Sounds like something is up with the battery. Try resetting it, there should be instructions out there. Is it still in warranty? Even if it’s not sometimes Valve is nice and will still fix Decks for free.
If you’re talking about battery recalibratiom, which is the first thing I found, I don’t think I can. Any post I see on it says to drain the battery as the first step, but I don’t have a clue whether it’s using any battery power while unplugged right now. So I’d have to hope the battery is draining and hope when I plug it in that it wouldn’t be saying it’s at full charge.
Edit:
I’ll have to quickly look and see if it’s under warranty. I’ve had it for less than a yearso it’s possible, but I don’t know if the refurbished ones come with warranty like the new ones. Will definitely look into that.
if the refurbished ones come with warranty like the new ones
they have the regular warranty. it’s basically one of their selling points.
But also: have you tried unplugging the battery and reconnecting it? maybe the connection is a bit flaky
I didn’t try because there were a couple ribbony clip things on top of it and I didn’t feel comfortable removing them, but I’ll try that next chance I get.
yeah, understandable. the ribbon is there to help pull it out. it pulls out sideways, which is a bit awkward. You can check ifixit disassembly tutorial to seee how to best do it
While looking up warranty info, I stumbled upon the ifixit stuff and planned on following their guide, so I’m at least good there.
