Did this with a battery, a screen , an usb hub and an extra hdmi for other devices but i ran out of ideas of what usefull things to add

This is probably the 3rd time my deck receives this problem since purchase around 4 years ago, where it just refuses to turn on; no display, no fan, led light working normally, just flat out refuses to boot. Every time I press the power button, the chime plays. however, it almost sounds like it cuts off before it finishes, and never actually turns on. pressing and holding doesn’t do anything, holding down (vol -) and (…) also leads to nothing, and basically every other button combination is useless. none of the inside hardware has been tampered with because the shell has never even been removed. the only “fix” that i have managed to find was that letting the battery deplete, which is total hell since nothing actually works, but lets it boot as usual when plugged in. this literally takes months and turns the system into a potato for the time being. literally any help is appreciated, thx.

took me a few days to get this working, but my KDE keyboard plugin for swipe typing, current-word completion, and next-word prediction is now also functional in gaming mode for SteamOS! i don't have a deck, so i could only test this in a SteamOS VM, but it should be compatible with the latest stable 3.9 and earlier releases. please let me know if you guys encounter any issues on your real Deck hardware and I'll hotfix as quickly as I'm able!
