Introduction

Before you begin, completely power down and unplug all cables from your Steam Deck. Remember to follow general electrostatic discharge (ESD) safety procedures while repairing the device.

These steps only describe how to physically remove and replace your console’s button board. You may need additional software tools and calibration procedures to get a replacement board to function as intended.

What you need

Step 1

              Remove the back cover screws

To minimize risk of damage, turn on your Steam Deck and allow the battery to discharge below 25% before starting your repairs. A charged lithium-ion battery can be very dangerous if accidentally punctured.
Before starting this guide, power down your Steam Deck and unplug any cables.
As an extra precaution, Valve recommends putting your Steam Deck into battery storage mode within the BIOS before starting any internal repairs. Read how to do that here.
If you have a microSD card installed, make sure to remove it before opening the Steam Deck.
Use a Phillips driver to remove the eight screws securing the back cover:
Four 9.5 mm screws
Four 5.8 mm screws
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your Steam Deck.

Step 4

              Uncover the hidden shield screw

Use a pair of tweezers to remove the piece of foil tape covering the hidden screw on the board shield.
If possible, try not to rip or tear this tape so it can be reused. If necessary, you can fashion a replacement by cutting a piece of aluminum foil tape to fit.

Step 7

              Disconnect the battery

Step 8

              Unclip the left trigger

The left trigger will be on your righthand side when working on the Steam Deck, as it’s laying upside down.
The Steam Deck’s triggers clip into place on two pegs on the trigger bracket, which doubles as the hinge.
Place the flat end of a spudger onto the inside edge of the trigger’s left clip.
Pivot the trigger clip out, away, and up from the peg to unlatch it.
During reassembly, latch the outermost peg first. Once in place, push down on the trigger to latch the innermost peg, producing an audible “click” sound.
Check to make sure that the trigger spring is properly aligned. Test the trigger action before continuing reassembly.

boop pert - Jun 15, 2022

Is the button board available for purchase, or planned to be available for purchase? My steam deck took a tumble and busted the left bumper button that the bumper presses.

Aaron Latta - Jun 24, 2022

I also have the same problem as boop pert.

I’d like to know if the board with be available as the Left Bumper is non functional now and needs to be replaced entirely.

Jordi Fernández - Jul 24, 2022

Got the same problem, my steam deck fall and broke the L1 internal button , and as i see is attached to the left button board. Is there any ETA to have this part available ? Thanks !

Jordi Fernández - Dec 23, 2022

Is there anything i can do if my problem comes from Left Button Motherboard ? Is there any replacement for Left Button Motherboard ? Any news about that ?

Tarek Elmeskine - Jul 27, 2022

I have my L1 button not responding anymore. After checking, I could see that it comes from the board itself. I have the same question that above me.

Will this board be available for purchase soon? If not, do you think that valve will still replace it if I send to the after sales service? Thanks
