X1 Carbon (20A7-CT01WW) not booting

Prior to this problem the machine was running fine, there were no major updates that I recall, I certainly did not do any firmware updates for example, probably only Windows 10 automatic updates.


So when this first happened there was a blue screen. The first few times it started booting windows and blue screened before reaching the login screen - now I can't even get the screen to come on, not even bios, just the following..


When I press the power button the keyboard backlighting and LCD Fn keys appear. The screen does not appear to start. Sometimes the machine stays like this for about a minute then switch off, sometimes it seems to reboot endlessly. When it is rebooting the power button flashes 3 times.


I have tried the following with no success:

Running on AC and no AC.

Charging for a day.

Letting the machine sit for at least a week off the charger.

Holding the power button for 3, 10, 20, 30 seconds, etc..

Pressing the power button multiple times.

Pressing the reset button with a paperclip.

Pressing the F1, F12, delete keys immediately on powerup, etc..



Any suggestions? I haven't opened it up yet, but I am comfortable doing that.
