    Hello,

    I updated BIOS to v1.21 what is specially for <Update MX130 VBIOS 82.08.77.00.29.>.
    Before update I didn't pay enough attention, so right now on my MX150 is MX130 vBIOS.

    Windows is not recognizing nVidias GPU, its not appearing in Device Manager (also as hidden not).

    I tryed to downgrade bios versions but with no luck.

    Is there any possibility to flash back MX150 vBIOS?

    Acer Aspire 5 A515-51G

    Kind regards,
    nr4400

      I downgraded BIOS versions successfully, but non of them contained MX150 vBIOS, I think.
      Or need to change something more to active vBIOS update?
      I downgraded to 1.20 > 1.19 > 1.15 > 1.12

      MX150 still not working.

      Do you recall what the BIOS version number was when the card was working? Jack E/NJ

      There is no v1.12 listed for your machine!!! Where did you download that one from?  Jack E/NJ

      Thanks @egydiocoelho . About when did you purchase the machine @nr4400 ?  Try to go back to the version that comes closest to that date. Jack E/NJ

      It came with BIOS V1.09, but I have no idea how to downgrade to that version, because its having different BIOSVersionFormat .N.NN.NN.

      My acer full model:
      Aspire 5 A515-51G-885Q
      P/N: NX.GTCEL.003

      And I checked that there are two different MX150 chips, and I don't know which is in my Acer:
      N175-G1-A1
      N175-LG-A1

      I see only few options:
      1. Best scenario that Acer create VBIOS update also for MX150 (same as it was for MX130 (with BIOS V1.21), what I accidently installed)
      2. Someone somehow copy its VBIOS from MX150 and share it with me.
      3. What I tried, downgrade to previous BIOS versions with hope that one of it contains MX150 VBIOS.

      Did you try both ways to downgrade to try to install v1.09 in my earlier thread? https://community.acer.com/en/discussion/comment/606726/#Comment_606726

      Now I successfully downgraded to 1.09, but it also didn't contained MX150 Video BIOS.
      MX150 still not working.

      >>>It came with BIOS V1.09>>>

      v1.09 was released Sept 26, 2017. Did you purchase the machine before or after this date? Jack E/NJ

      If this bios only works correctly on models with mx130, why did not Acer lock out that version of bios 1.21 for models with mx150? I consider this problem a serious mistake on the part of Acer! There should be some kind of blockage!
      I think a possible solution would be to rewrite the bios with a low level program like dmitoolsx64! However this procedure is much riskier than the bios downgrade itself!
      I think you should try downloading bios soon for the first version available on the site! The 1.05 version!

      Probably. But I have an uneasy feeling that the machine might've been purchased before June 27, 2017 with a version even earlier than v1.05. Jack E/NJ

      I bought laptop approximately 3 months ago.

      That was my question too, because usually there should be some validations, but in this case there wasn't any.
      But I'm not sure which BIOS version contains MX150 Video BIOS. Of course I can try to downgrade to V1.05 using some low level tool and hope that would help.

      @nr4400Only a question! In the device manager, is the video card also being recognized as mx130? I do not think it's worth it as you try to downgrade the bios by rewriting the bios with dmitools because, as I told you before, it's a much riskier procedure than the downgrade itself! You can try lowering bios to version 1.05 in the same way you are currently trying!

      As I mentioned before, nVidias GPU is not showing in Device Manager (also as hidden not).
      Okay, than I will try to downgrade to 1.05 using the same method as for previous downgrades.

      To add to the confusion, the earlier MX150 models came with two versions of the MX150. Refer to this thread. May have some nuggets. Jack E/NJ

      If v1.05 doesn't do it for you, I suggest double-checking what you have with GPUz. If it a 150 variant, it probably would be safer to let ACER warranty repair service fix the BIOS firmware. Jack E/NJ

      If OS is not seeing GPU then soft also will not see it.

      I will try to go with service, but I'm not sure if they will take this case in warranty.

      Could the recovery crisis method solve this problem? Would this violate Acer's ACUA agreement that was recently made available to ACE users?
