Hello,
Thank you for your previous reply.
I have already
reprogrammed the full BIOS on the
DA0NJHMBAH0 REV_H motherboard after replacing the
SRKMA (Southbridge/PCH).
The programming was successful (erase → write → verify OK), but the
issue remains unchanged.
Symptoms:
- After power on, the board draws about 0.6 A, then rises to 1 A, stays for a few seconds, drops to 0.15 A, then repeats the cycle (0.6 A → 1 A → 0.15 A → …).
- All voltage rails are present and stable.
- The new SRKMA no longer overheats.
- No display output.
Since the problem persists after a clean BIOS reflash, I suspect the BIOS content may need
correction (e.g. ME region clean, DMI/MAC/NVRAM data alignment, EC/Bios synchronization, or board ID fix).
Could you please:
- Repair or rebuild the BIOS so it is fully compatible with the replaced SRKMA and this exact board.
- Provide a correct EC firmware for MX25V8006EZNI (1.8 V).
- Let me know if I should send you my saved EC dump to assist with the repair.
Once I receive the corrected files, I will reflash both the main BIOS and EC and retest the board.
Thank you for your support — I’m ready to proceed as soon as you provide the necessary files or instructions.
