Hi everyone,
I’m posting this in case it helps someone else, because I spent hours reading Reddit threads and almost opened my Steam Deck unnecessarily.
Device
• Steam Deck OLED
• Stock, not modded
⸻
The problem
Out of nowhere, my Steam Deck entered a really bad state:
• Screen completely black
• Fan ramping to maximum speed in pulses
• Power button would NOT shut it down, even holding it for 10–20 seconds
• LED kept blinking / staying on
• Could not enter BIOS or Boot Manager
• Basically stuck in a power/firmware loop
The only way to stop the fan + LED was using “… (Quick Access) + Power”, which fully killed power — but every time I tried to boot again, the problem returned.
At this point I saw many Reddit posts saying the only fix was disconnecting the battery, and I even bought tools to open it.

What actually fixed it (no disassembly)
⚠️ Important details
• My Deck was OLED
• The successful reset happened without the charger connected
• Battery had been charging beforehand
⸻
Step-by-step solution
1. Charge the Deck with the official charger for at least 1 hour
• Do NOT try to turn it on during this time
2. Unplug the charger
3. Perform a deep EC / firmware reset:
• Hold Volume – + “…”
• While holding them, press Power once
• Release everything
4. Watch the LED
• Mine blinked blue twice
• Then blinked white
• Then turned off completely
(This seems to indicate the EC reset actually executed)
5. Wait 3–4 minutes
• Do not touch any buttons
6. Plug in the charger
• Do NOT press Power
👉 After a few seconds, the screen turned on by itself and the Steam Deck booted normally.
⸻
Result
• Booted into SteamOS
• Screen OK
• Fan OK
• Sound OK
• Wi-Fi OK
• Buttons OK
• System stable
I’ve rebooted it multiple times since and the issue is gone.
⸻
Important conclusions
• This looks like a stuck EC / firmware power state, not a dead device
• Disconnecting the battery physically was NOT necessary
• The Volume – + “…” + Power (single press) reset seems equivalent to a hard EC power cut
• Doing this without the charger appears to matter
• Plugging the charger after the reset allowed the system to recover cleanly
⸻
Advice
Before opening your Steam Deck or disconnecting the battery:
• Try this reset carefully and patiently
• Watch the LED behavior
• Give it time after the reset
Hopefully this saves someone else a lot of stress (and money on tools 😅).
