UNSOLVED
XPS 13 9350
I have a POST issue, the laptop will not start will briefly flash Dell logo the hangs have tried the CMOS reset and new CMOS battery but still not working.
Carried Out DELL diagnostic by Holding FN while Powering ON code is 4-1-5, from a search this sounds like a MB problem..
Anyone got any ideas ?
Unplug the system and disconnect the battery from the system board. Hold the power button for 30 sec and see if the system will then POST. If not:
Remove the SSD and/or hard drive and see if the system will then POST. If it will, you have a bad drive.
If the system still won't POST, you have a bad mainboard.

@ejn63 is spot on with the directions. I am curious though, with the 415 code was a specific cable named? Did you run diagnostics with the adapter plugged in?
