Where is the Bios on the mainboard located, is there a battery for the Bios?
This is the 2024 model… not much info around, in the previous models, there’s an IC covered above the Wi-Fi card and/or another in bottom board below thermal plate, this is not easy to identify with all cooling and covers on it, the machine needs further disassembly, it even could be in the opposite board side.
