简介

Use this guide to replace the left bumper button (L1) in your Steam Deck.

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.

    • 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.

    • Use a pair of tweezers to remove the piece of foil tape covering the hidden screw on the board shield.

    • 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.

All good! but you are missing the last step as you will need to replace the Dpad contacts and place them on the new bumper.

I broke the Step 17 connector's support, with no preassure, just as a lever, any idea on replacing the DAF7ATH16F0 Rev F (last 0 may be a O) board? I will solder the broken connector but I don't think I will be able to, so small

This part is not available in Canada, I've seen your product advertised all over the tech industry, but this part is not available to ship to Canada, that's too bad, I would have purchased the repair kit along with this part, I guess I'm stuck with the rma process. I guess right to repair is still very broken.

Any news on when this part will become available for purchase?
