Hello. LED n2 does not light up, what could be the problem? How could I check it? Is it necessary to have the ram and processor mounted on the motherboard for it to turn on? Thanks

andre.dias.tui you are looking at LED 1 which means you need to check LED Startup Sequence
LED #1 = Power available.
If LED 1 is on but LED 2 does not come on, you will need to check:
• Verify power button connection to logic board
• Verify power button functionality
- Disconnect power button from logic board. Inspect cable and connector for damage. Verify continuity between the two pins of power button when it is pressed.
• Verify cable connection between power supply and logic board
• Verify power supply
• Verify logic board
I would start by checking the power board voltage output to the logic board. You can measure that on the power connector from the power supply.
