Introdução

Use this guide to replace the motherboard 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.

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

    • 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.

    • Insert an opening pick into the thin gap between the back cover and the front shell, along the edge of the right grip.

    • Pry up on the back cover to release it from the locking clips.

    • Once the clips are disconnected from one edge, the rest disconnect easily.

    • Grip the back cover at the opening you just created and pull it up and away from the device to unclip the long edges.

    • Remove the back cover.

    • 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.

    • With the SSD screw removed, the SSD will pop up at a shallow angle.

    • Grip the end of the SSD and pull it away from its M.2 board connector to remove it.

    • During reassembly, insert the SSD at a shallow angle into its board connector, and secure it back into its horizontal position with the SSD screw.

    • Use a Phillips driver to loosen and remove the two screws securing the heatsink to the motherboard:

    • One captive 3.5 mm screw

    • One 3.4 mm screw

    • No, your eyes don't deceive you! The third heatsink screw was removed earlier in the disassembly: it doubles as the hidden board shield screw.

    • Pull straight up to disconnect the cable.

    • Repeat for the second antenna cable.

    • During reassembly, ensure that both antenna cables are reconnected at their appropriate connectors. The labels on the cables match the markings on the Wi-Fi module.

    • To reconnect each cable, align the connector directly over its socket, and then press down so it snaps into place.

When will I be able to buy the motherboard?

Jing - Responder

What is the actual size of the screws (M1.6, M2 , M2.2) as this information would be helpful if someone was to lose a screw while carrying out a repair or re paste.
