    • Turn on your Steam Deck and allow the battery to discharge below 25% before starting your repairs, as a charged lithium-ion polymer battery can be dangerous if accidentally punctured.

    • 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.

    • Power down your Steam Deck and unplug any cables.

    • If you have a microSD card installed, make sure to remove it before opening the Steam Deck. If you attempt to remove the back cover with it still installed, it could snap right in half.

    • During your repair, it can be helpful at times to lay the Steam Deck face-down into its case to protect the thumbsticks and prevent wobble.

    • Use a Phillips driver to remove the eight screws securing the back cover:

    • Four coarse thread 9.5 mm-long screws

    • Four fine thread 5.8 mm-long screws

    • Despite the standards, Phillips screwdrivers can vary in size and shape—two drivers labeled as the same size may fit differently in the same screw. Use the size that fits the snuggest into the screw head.

    • 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.

  3. Steam Deck - Ultra Battery, Unclip the back cover: crwdns2935265:03crwdnd2935265:01crwdnd2935265:02crwdne2935265:0 Steam Deck - Ultra Battery, Unclip the back cover: crwdns2935265:03crwdnd2935265:02crwdnd2935265:02crwdne2935265:0
    • Insert an opening pick into the thin gap between the back cover and the front shell, along the edge of the right grip.

    • If you're having trouble inserting your pick at the grip seam, try starting at either the top or bottom long edges first, then slide the pick towards the grip.

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

    • The SSD is wrapped in ESD shielding that will need to be transferred to the replacement SSD. Alternatively, replacement shielding can be found here.

    • Slide the shielding off of the SSD.

    • If the shielding feels stuck, use a pair of tweezers to peel off and remove it instead. Take care to keep it in the best condition possible if you want to reuse it.

    • Only the SSD remains.

    • The Steam Deck uses a single-sided M.2 2230.

    • To recover, repair, or re-image your SSD, follow Valve's Steam Deck recovery instructions.

    • Note: The Steam Deck's buttons, thumbsticks, and touchpads may not register inputs at first after re-imaging the SSD. Use the touchscreen to follow initial SteamOS setup, allowing the device to download updates. Functionality should return once the Steam Deck restarts.
