and this is the schematic + boardview of the motherboard which is exactly the same as the board I have

i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly.

how do i know that my CPU is good or bad.?
after I checked there was no short circuit on the board, all the power on the board was all good. The laptop seems to want to turn on but is unable to boot​

The LED light on the power button is green, which I'm confused about, usually blinking slowly indicates the laptop is in sleep mode, but in this case the LED light is blinking quickly, sir.

and it's true that the boardview you shared is exactly the same as the laptop model I have, sir
Sorry sir, i don't have the boardview link

hello guys
i have a problem with lenovo X1 carbon gen 2 laptop, with motherboard code "LMQ-1MB 12298-2 48.4LY07.021"
The main problem is that when I plug in charger, the power LED indicator flashes 4 times, the fan spins for a moment then turns off again and keeps repeating, I've tried flashing the BIOS but the result is still the same
I hope someone can help me ​
