    Re: BIOS for Asus X450VP rev2.1 with ATI graphics

    Does anybody know why ME_AC_PRESENT does not go high?

      I think could we ignore the signal ME_AC_PRESENT. Just go to check signal 1.5_ON, might be that signal was present after you pressing power button. If yes, then check on Low side mosfet on block 1.5 (pin 4 PQ8301/pin 15 PU8300). Because signal En for controller 1.5VO coming not from SUSC signal. Just guessing, maybe this point was clue the problem.

        signal 1.5_ON is not present.
        SIO generates RSMRST and 3v_SUS_ON and other signals after pressing the power button.
        should be they generated after plugging adapter in before pressing the power button?

          What I thought if there's signal premature, seem it not happen. Signal 1.5_ON generated after pressing power button.

          Asus X450VP seem as revision of X450CC, as far I know it board almost had problem only with regulator 3V and 5V.

          does +12VSUS have correct voltage?
          does 3VSUS_PWRGD signal present?

            both 12VSUS and 3VSUS_PWRGD are present. may be, this board can not be fixed.

              I do not know why PM_SUSC is not generated by PCH.
              In this laptop, BIOS chip is connected to SIO. SIO reads BIOS, but PCH does not.
              Does PCH read BIOS before generating PM_SUSC?

                does anyone know at which stage PCH reads Bios chip for the first time during startup?
                is it S4 , S3 or S0?

                  I need Bios for Asus D452V Laptop.
                  mainboard model: X450VP REV. 2.1


                  note1: my original bios in post 1 and 2 are probably damaged, because I tested them and got no result.
                  note2: I already got bios of mainboard x450cc rev2.1. I tested it. It was good considering SIO but PCH does not turn on. I downloaded it from this thread: https://www.badcaps.net/forum/showpo...13&postcount=2

                        I carefully looked at the markings on the laptop. I realized that laptop model is Asus X452CP. So I appreciate if someone uploads bios dump for this laptop:

                        Laptop model: Asus X452CP
                        Mainboard model: X450VP REV. 2.1

                        the original dump is in the first post that does not work.

                              it did not work because the SIO and the PCH seem faulty.

                                note: I already got boardview for X450CC, but it is a bit different.

                                    The mainboard was not fixed. I'm gonna replace the mainboard by a new one.

                                        Finally, I figured out the PCH was faulty. The bios dump I uploaded in Post 1 is faulty too. I recommend you use the Bios dump in the following threads:
