Hello everyone,
I’m trying to recover an ASUS TUF Gaming A17 FA707NUR (Ryzen + RTX 4050, 2023 model).
The laptop powers on, fans spin, but the dGPU (NVIDIA) is not properly initialized — sometimes it shows up in Device Manager with Code 43, sometimes black screen.
After several BIOS downgrades/upgrades (versions 300, 301, 303) and EC resets, it thinking looks like the EC firmware (IT5570VG-256) might have a persistent fault or flag stored in flash.
I already extracted the BIOS .CAP files and DXE sections with UEFITool and IFRExtractor, but I couldn’t find any separate EC binary region.
If anyone has a verified clean EC dump (.bin, 128 KB or 256 KB) for this board (FA707NUR / FA707NU, same revision), it would be very helpful.
Board info:
Additionally, in the boardview I located a J1 jumper that connects GND and +3V_RTC.
If anyone knows whether this or any other pad combination can safely force an EC reset / RTC clear (without reprogramming), I’d appreciate the info — just trying to confirm if ASUS designed a manual reset path for the EC flags.
Thanks in advance — any EC dump, partial read, or reset tip would be great to help restore this unit.

Board info:
- Model: ASUS TUF Gaming A17 FA707NUR (2023)
- EC: ITE IT5570VG-256/CX (marked as KU1 on the board)
- I can flash via CH341A + SOIC-8 clip or through service pads (TP_ECCLK, TP_ECDAT, TP_RST, etc.).
Additionally, in the boardview I located a J1 jumper that connects GND and +3V_RTC.
