Steam Deck won't charge or shows 'slow charger' (USB-C power checks)
Most Steam Deck charging complaints come down to the charger or dock, a confused USB-C power negotiation, or a battery issue, rather than a broken port. Work from the charger and software checks through battery storage mode and a USB meter reading before opening it; the USB-C port is soldered to the motherboard, so a damaged port is board-level work.

Steam Deck stick drift: calibration, deadzone and thumbstick module replacement
Steam Deck drift is usually a worn or dirty thumbstick, out-of-date calibration or a poorly seated ribbon cable. Recalibrate and adjust the deadzone first; if it persists, the stick is a separate module held by three screws and one ZIF cable, and is quick to replace - but LCD and OLED models use different screws and different modules.
