Boot problems, strange diagnostic leds.
My 2015 EMC2833 gave up on me and I don’t have a clue what it could be.
Are there any schematics available for this model? MB nr. 820-00431-A I have googled for a long time with no success.
I have removed the LCD to access the diagnostic leds.
When I connect power, both LED 1 and 2 lights up within 3 secs without me pressing the power button. if I push the power button the leds turn off and comes right back on again 2 seconds later.
But if I hold the power-button while inserting the power cable only led 1 lights up.
If I then release and push the power-button again led 2 lights up but no chime or fan-spin.
If I then hold the power for 6 seconds led 2 goes off and 1 stays on.
Why is there a difference if I hold power-button or not when inserting powercord?

My computer don’t power up could be the problem. Maybe power supply
