My surface pro 3 has stopped receiving power. The light on the charging cable does not turn. To troubleshoot the problem I purchased a brand new power cord and used a different outlet to plug in. It still did not charge and the light in charging cable did not turn on either. I then went through the painstaking process of opening the surface and replacing the charging port from inside. Plugged it in and still has the same problem! Can someone please help me troubleshoot from here on. I would greatly appreciate it.
Thank you in advance!
