System fails to power on via BIOS, no visual output, input devices unavailable
It seems like you're wondering if the issue is with a dead CPU or motherboard and whether they should be taken to warranty service.
You're questioning whether your new components failed shortly after installation. It seems unlikely they died, but you're worried about using them again. The USB setup worked fine—your phone charges normally—so the issue might be with the drivers for your mouse and keyboard. They could be inactive because the system isn't booting properly.
Sure, let me clarify. You’re connecting your phone, keyboard, and mouse to the same USB-C port, but only your phone charges. Why? It might depend on how each device communicates with the port or how the charging system is set up. The keyboard and mouse may not be receiving the correct power signal or voltage.
Keyboard and mouse require a signal to function, while a phone only needs a voltage to charge.
