    • 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 in its case to protect the thumbsticks and prevent wobble.
