I have a new Dell XPS 13. When attempting to boot the front led blinks amber twice, then white twice repeatedly. The device never boots to the dell logo. This is with the AC plugged in and the battery test showing no issues.
Please list exactly your Dell model. Example: Dell XPS 13 9350
Secondly, I like to suggest you try the steps below
A) Disconnect all peripherals(printer, external drive, etc...) from computer
B) Power off computer
C) Unplug the AC adapter from computer and wall socket
D) Press and hold in the "Power On" button for 15 seconds then release
E) Plug in the AC adapter into the wall socket, then the computer
F) Press the "Power On" button. Hopefully your computer run normally
If those steps didn't work then I like to suggest you run the Diagnostic tool on your computer to scan for hardware problems.
A) Power off computer
B) Power on computer, quickly tap the F12 key continuously. You should be in the Diagnostic screen. Please list any error codes.
I faced with next blinking pattern "twice orange, one white" on my Dell XPS 13 9350 DE. Non of these two suggestions do not help :( Neither Fn+PowerON doesn't help. Does anybody had such behaviour? Any other suggestions?
