My steam deck stopped charging, bought a new charger to be safe but still no dice. Opened her up and reseated the battery then tried the charger again. There was a hissing sound so I immediately unplugged it. The port smelled like burning, but after removing the board, there are no visual signs of burnt components. I do have access to a hot air soldering station, but I’m not even sure if it’s just the port that’s damaged at this point. Anyone replaced the USB-C before? Anyone had to ship their deck to a repair center?
Definitely a battery-related issue. When I first got my Deck a year ago I actually had a very similar experience. Turns out the power regulator IC that controlled the voltage from the battery got itself fried, so not only did I get the burning and hissing but it just straight up refused to boot and charge.
If you want to you can try diagnosing the issue further… but yeah, RMA time. It’s so much easier.
