M17X R2/3/4 BAD GPU BIOS

1 post in this topic

Hi All,

I have recently purchased a dell 770m to revive my M17X R3 with a broken 580m inside.
 
  • I have flashed it to the unlocked A12 Bios, Disabled integrated graphics, set the display mode to PEG, and disabled integrated audio.
  • It could boot with the 770m but it was not detected, so the vbios needed flashing. I tried flashing to a 770m Dell vbios, however the PC will not boot with the GPU in now.
  • Upon doing a blind flash back to the default A12 bios, I can get the laptop to boot without a GPU, but with a GPU it hangs on the red bar on the bios splash screen.
  • I need to know how to blind flash my GPU back to a working BIOS, every attempt using END+power in just seems to reset the default bios, re-enabling iGPU etc.
  • I have a memory stick prepared with a better 770m BIOS along with nvflash and an autoexec.bat file, however I cannot get it to boot as it just hangs on the splash screen with the GPU in.

Thanks,
Alex

TL;DR - GPU has a bad BIOS, how do i re-flash it if it can't boot.

      Hello guys, how are you?
       
      I got today a new graphics card for my Alienware 17 R1 (2013). The newer card is a gtx 970m. Before, the Alienware had no dedicated graphics card, but only the integrated Intel HD 4600 from processor.
      After I put the new card on laptop, I realized that the laptop wont turn on anymore. If I remove the graphics card, laptop turns on normally.
      Another thing that I noticed, is that with graphics card inside  when I plug AC adapter, the blue led of it (AC adapter) turns off. Without the card, this behavior dont happens.
      I already reseat the card a lot of times without success.
       
      My Alienware is a R1 Model (2013) or M17x R5.
       
      PSU: 240w
      Processor: 4910mq
      RAM: 32GB
      Battery: OK.
      Graphics Card: Alienware GTX 970m 6gb - G16E-A1
      Bios: A14 (lastest from Dell WebSite)
       
      I dont have another card to test.
       
      Thank you guys. I hope anyone can help me.
