Hi,
I have a problem with my Lenovo x1 carbon 2nd gen - LMQ-1MB 12298-2 48.4LY07.021 .
New bios have been flashed because the previous one was corrupted but this still didn't resolve the issue with no display. The laptop now is experiencing no display and is turning of by itself after 1-2 minutes.
This are the voltage and resistance reading on the COILS
L1 - 1.73V 58Ω
L3 - 5.1V 1.7kΩ
L4 - 3.3V 11kΩ
L5 - 0.7V 38kΩ - when the battery is connected showing 16.4V
L7 - 1.35V 122Ω ...

I was using Asprogrammer to flash these two files but it is giving me the error: Press "Unprotect" and check datasheet"]
Used neoprogrammer to flash it but the laptop still don't show nothing on the display.
Any more advice.
Many thanks
