Hello sir, We are still learning with your tutorials. I got a chrome book Asus C200M when I connect the charger only orange light blinking no power on. First time am working with the chrome book. I try to hard reset but not work. I disconnect the internal battery still am getting the same problem kindly tell what to do next. I don't have schematic or board view and I don't know the voltages of this Motherboard. Motherboard No is DA00C7MB6E0 REV.E

Hello
First, Check the resistance of different parts of the motherboard with a multimeter in the ohm range.
If the resistances are normal, connect the adapter and start measuring the voltage.
You should measure the adapter voltage from the input jack.
Then measure the voltage on the sense resistor.(B+)
This voltage enters the IC power and the 3.3 V LDO voltage is created by the IC power internal regulator.
This is the main supply voltage of IC IO.
Check the voltage of 3.3 volts on the switch button and the voltage should drop by pressing the button.
If everything was correct until these steps, program the BIOS.
