Hello everyone,

I’m repairing an HP OMEN 17-ck0048tx with motherboard DA0G3LMBCF0 Rev F.

GPU is RTX 3060 (GN20-E7-A1)
Panel is 17.3" QHD 2560×1440 165Hz (M57128-001)
CPU is Intel i7-11800H.

Original fault: laptop powers on, but no display.
With RAM installed: fans spin continuously, no keyboard, no display.
With RAM removed: CapsLock blinks 3 slow + 2 short (RAM error), confirming POST execution.

I have:

✔ Original 16MB BIOS dump
✔ EC (W25Q80) dump
✔ HP SoftPaq sp162936.exe
