    No display, Eluktro Pro (Clevo) P650HP6, board number 6-71-P65P0-D02A

    This laptop came in as no internal display. I did see it boot on an external monitor but it was not consistent, however, the bios splash screen was consistent. The customer said it happened after a windows update. I tested the display and there were no signals on the LED_EN or PWM test points. At this point I decided to treat it as a bios issue. I disconnected the RTC battery and drained the residual power. After this, I did not get the bios splash screen anymore. The power led changes colour, fans spin, GPU and CPU get warm and caps lock is functional. I tried the bios from the Clevo repo, there was a file with the same size as the original bios dump but with a ".12" extension, I renamed it to ".bin". I did try to clean me with no improvement.
    Hoping I can get some assistance with this one, thanks.

      Hello, I have a bricked Eluktro laptop, can't seem to find a bios dump. I would like to have the ME cleaned please. The bios download from the Clevo repo has a file with a ".12" extension that is the same file size as the original bios but it is "configured" as opposed to "initialized" according to ME analyzer. I tried it and the laptop still did not boot.
      Can anyone help me clean ME or repair this bios please? I attached both files....

      Convert Clevo PC70DD to UMA
      by TecnicaNTT
      Can somone please help me unlock or convert this Clevo PC70DD2 BIOS to UMA only?
      The motherboard just burned a hole in the GPU VRAM VRM circuit and now there is a 19 Volt short spread across the GPU and VRAM side. I isoalted both circuits from the rest and now I can get the laptop to work and display image with integrated Intel graphics but crazy fan spin and shutdown after some minutes because of missing dedicated Nvidia GPU.

      Does the Oak OTI067 have a splash screen / initialization message at bootup?
      by Scruit
      tl;dr ... Question: Does the Oak OTI067 have a splash screen / initialization message at bootup?

      More detail:

      Working on "Uncle Sherman", my Mitsubishi MP-3200 386 from 1988. Before I start up old computers I have a process where I disassemble, test for shorts, visually inspect, capture EPROM images etc.

      My T866II+ give me a "pins not detected" error on the EPROM from the Oak-based (OTI067 GPU but apparently a no-name card??) I assumed the EPROM was bad, ordered a replacement and figured I'd program a downloaded ROM image to it....
