Symptoms:

My ~2 years old Alienware x15 R2 stopped working. Power light and keyboard turn on, power light flashes 2x red and 3x blue, screen stays black.

Dell error codes indicates this is the error

2,3 No memory or Random-Access Memory (RAM) detected

After disassembling and removing the battery after discharging any static electricity by holding the power button without the power cable connected, symptom persists.

After removing the motherboard and disconnecting all cables, keeping only the PSU and display cables connected, it powered on and showed the UEFI ("BIOS") recovery screen.

However, since USB and keyboard weren't connected I couldn't perform the reset. So, after shutting down the system and reconnecting the keyboard, the system stays with a black screen. Then I removed all cables again, keeping only display and power as before, and the screen is still black and not even going into UEFI recovery no matter how many times I tried.

I couldn't find any schematics of the board to try to diagnose it further. I was thinking about reprogramming the firmware with my programming tool but I noticed there are around 3 or 4 Winbound chips and I am not certain which one is actually the main UEFI one or if I could find a working dump for this system.

The motherboard is LA-L611.

Any help is truly appreciated.
