3,5 is a power rail failure. Since the system is new enough to be under warranty, contact Dell support to have the mainboard replaced.

On the rare occasion, a power reset can fix your issue. Unplug the power adapter and hold the power button down for 60 seconds and then try to boot. If this doesn't work, try unplugging the system battery and try the power reset again. Check the service manual for the m18 R1 to show you how to safely unplug the battery.
If neither of these options work then you will have to open a support ticket, hopefully you still have warranty.

If the system is under warranty, simply call Dell support.
