It can be a very scary moment when a Steam Deck that you paid good money for won't turn on. Fortunately, you can try a few things before resorting to an expensive repair. This wikiHow article teaches you how to troubleshoot a Steam Deck that won't turn on.

Things You Should Know

  • Press and hold the power button for 10 seconds to do a forced Restart. If that doesn't work, see if you can boot into Recovery by press Volume Down and Power.
  • Check to make sure your charging cable is working. Try using a different USB-C cable or charger. Try plugging it into a different wall outlet.
  • Check the power button for damage or stickiness. Check the charging port for dirt or debris. Clean the charging port with condensed air or a toothpick shaved to fit.

  1. Also check to see if you hear any system sounds, or fans, or see backlighting on the screen.
    • If the screen is black but has backlighting, the problem is most likely with the system not booting up properly rather than a power problem.
    • If you hear fans or system sound, but nothing is displayed on the screen, connect to an external monitor using an adapter or dock. If you can get an image on an external monitor, the screen is most likely faulty.

  1. Make sure the charging cable fits all the way in and is snug against the shell of the Steam Deck.
    • You can use a flashlight to look inside and see if you spot any dirt or debris. If it looks dirty inside, you can clean it with condensed air.
    • If there is any large debris that won't come out, you can clear it out using a wooden toothpick shaved to size. Do not stick anything metal inside the charging port.
    • Using a USB multimeter, you can check if the charging port is working properly.

  1. If it feels sticky or feels like it's not pressing down, try cleaning it with a cotton swap lightly soaked with 70% isopropyl alcohol. Make sure your Steam Deck is powered off when you do this.
    • You can also use a dry toothbrush or toothpick to get into the crevices.
    • If the power button feels loose, the button mechanism may have come loose from the motherboard.
    • If you are skilled at soldering , you can try to solder the power button back to the motherboard. If you are uncomfortable doing this, you'll need to take it in for a repair or try to warranty your Steam Deck.

  1. Let go of the buttons when you hear a chime. If your Steam Deck can boot into Recovery Mode, there is most likely an issue with the operating system.
    • Once your Steam Deck boots into Recovery Mode, select the option to reinstall Steam OS. This will reinstall the operating system while attempting to preserve your games and user data.
    • If reinstalling the operating system doesn't work, select the option to re-image your Steam Deck. This will reset your Steam Deck to its factory saving and erase all your games and user data. [3]

Check for Battery Failure

  1. Battery swelling may result in the battery becoming dislodged from its enclosure, localized discoloration on the screen, or bowing of the Steam Deck shell.
    • If the battery has swelled, remove it, and do not attempt to power your Steam Deck on.
  2. To do this, you will need to remove the screws from the back of your Steam Deck and open it. Then you will need to remove the metal cover and disconnect the battery.
    • Once the battery is removed, connect the Steam Deck to a charging cable and try to power it on. If it powers on without the battery, the battery has most likely failed. If it does not turn on, replace the battery and see if it powers on.
    • You should only attempt this if you are comfortable working on electronics.
