Re: I need help with Lenovo E14 laptop. FE4A0/FE5A0 NM-C421 REV 1.0
I have measured resistance.
black tip on gnd and red on USBC_VBUS20, mark 192.5.
and red tip on gnd and black tip on USBC_VBUS20 and it shows 54.9 ohms.
leave marked on a picture the point where you measured resistance...

Re: I need help with Lenovo E14 laptop. FE4A0/FE5A0 NM-C421 REV 1.0
the voltage is injected into PR0201. The problem I have is that I don't receive any voltage in USB C, I have tried several chargers.
What would the CC lines be?
what is the PD-controller? in this case it is u6301?...

Re: I need help with Lenovo E14 laptop. FE4A0/FE5A0 NM-C421 REV 1.0
The equipment works with 20v, which is why I injected that voltage, not to mention that I tried with lower voltages before and with 20 it turned on.
I can't find any voltage in the type c connector of the motherboard...

Apparently it does not receive voltage from the charger, this is type C.
I have injected 20v into the sensing resistor and the equipment does turn on and give video.
I have not been able to understand how the equipment that uses a type c charger works. I can't find boardview and I'm guiding myself with the schematic that I leave attached.
I hope someone can give me some help to find the problem.

Thank you very much Mon2 for the reference, but in the end I will have to ask for the adapter for my programmer and try with the file that SMDflea shared, I am very grateful to you, regards

Laptop Aorus RX5M SE4 don't show video signal
Hello, I have received a Gigabyte Aorus 5 Laptop model RX5M SE4. Due to a failed BIOS update, it no longer gives video. I don't have the adapter for this type of chip that comes with the motherboard, does anyone know if there is any way to fix it from usb. Or someone who can share the BIN file to reprogram it even if I have to send for the adapter for my programmer.
I leave some reference photos.
Thank you for your attention and help.
