Prepare your Steam Deck for disassembly
- 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. [guide|149962|Read how to do that here|new_window=true].
- 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, [post|744361|it could snap right in half|new_window=true].
- 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.
