To fix your Steam Deck touchscreen, first, turn it off. Next, boot it into BIOS Mode, and then go to Battery Storage Mode. Lastly, plug it in and turn it On.
Don’t worry! I am going to explain each of the above steps in detail.
Step 1: Boot into BIOS Mode
To put your Steam Deck into battery storage mode, follow these steps:
Turn off your Steam Deck from the power menu by selecting the Shut Down option.
Now, boot it into BIOS mode by pressing and holding the Volume Up and Power buttons together until you hear the chime.
Step 2: Go to Battery Storage Mode
- Once your Steam Deck is in BIOS Mode, open the Setup Utility option.
- Next, go to Power on the left side and select Battery storage mode.
- Next, select Yes.
Your Steam Deck will power off again, and its power LED indicator will blink thrice to confirm that it’s in battery storage mode.
Step 3: Plug it in using its Charger
Now, plug your Steam Deck in using its provided power supply and turn it On.
It is essential only to use the charger that came with your Steam Deck, as it does not support USB PD or Fast Charging.
