Internal Battery Pack
The Lithium-ion Battery Management System (BMS) can enter a permanent 'tripped' or lockout state if the voltage drops below a critical safety threshold (deep discharge). Once this hardware safety flag is set, the battery will refuse to accept a charge or output power, resulting in a completely unresponsive device.

Mainboard (LCD Revision)
The motherboard contains the primary Power Management Integrated Circuit (PMIC) and the soldered USB-C charging port. Failure of the PD controller or mechanical fracture of the USB-C port traces prevents the unit from negotiating the 15V power rail required for operation and battery charging.

45W USB-C AC Adapter
The Steam Deck requires a specific 15V/3A Power Delivery (PD) profile to boot from a dead state. If the internal switching circuitry of the adapter fails or cannot complete the digital handshake with the console, it will fail to provide sufficient wattage to initiate the boot sequence.
