MBP 13 No Power Or Charge Light

Heya, purchased a Late 2013 MacBook Pro Retina, has no water damage or drop damage etc and just stopped working one day. When plugged in there is no light on the charger, any ideas what it could be or how to diagnose the issue? Could it be the magsafe port? I know for certain its not the charger cable itself. Any input is highly appreciated!

This could be the DC-IN board, but more than likely this is a board-level problem. You could try replacing the DC-IN board if you’ve ruled out the power adapter already with an Apple branded, known-good charger. If this does not solve the issue you will need to further troubleshoot.

You will need a schematic and boardview file for your logic board. These can be found by Googling. You will also need a multimeter and likely a soldering iron or hot air station to repair this.

On page 51 of the schematic you will find the SYS_ONEWIRE circuit diagram. This is where you should begin troubleshooting. You should probably watch some of Louis Rossmann’s YouTube videos on the SYS_ONEWIRE circuit before attempting to repair this if you are not experienced with troubleshooting at this level.

Time to grab a good digital multimeter and find the schematics & boardview drawings for this system to trace the power rails. Look for 820-3436 logic board.
