    Dell Latitudes 7490 has no short circuit but turns on for 5 seconds and the power supply drops to 0 W consumption.

    Do you have any idea what it could be? Thanks.​

    Could be a short circuit in the late sequence. More informations necessary about the power supplies coming on/not.coming on and also resistance measurements from.all secondary power supplies suggested.

    How much current draws the board at max?
