Does anybody know why ME_AC_PRESENT does not go high?

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

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

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

Re: BIOS for Asus X450VP rev2.1 with ATI graphics
both 12VSUS and 3VSUS_PWRGD are present. may be, this board can not be fixed.Comment

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

Re: BIOS for Asus X450VP rev2.1 with ATI graphics
does anyone know at which stage PCH reads Bios chip for the first time during startup?
is it S4 , S3 or S0?Comment

Re: BIOS for Asus X450VP rev2.1 with ATI graphics
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=2Last edited by caspian; 11-14-2017, 04:33 PM.Comment

Re: BIOS for Asus X450VP rev2.1 with ATI graphics
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.Last edited by caspian; 11-18-2017, 01:02 PM.Comment

Re: BIOS for Asus X450VP rev2.1 with ATI graphics
it did not work because the SIO and the PCH seem faulty.Comment

Now I need boardview for Mainboard model: Asus X450VP REV. 2.1
thanks If someone uploads it.

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

With ASUS, not everything is quite so simple. I will show you my way. It may be longer or harder but it is the right way to do it in my humble opinion.
For example, you can have 3 similar ASUS motherboards, all being the same model, all of which will have different BIOS versions.
I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.
This is the picture of 3 similar ASUS motherboards, all of them being X555LD... -
Hi,
I have a serious problem to program the Z590 chipset SRAM with a Management Engine after replacing the chipset.
The new chipset is factory new and is not containing any Management Engine. Any attempts to program it into the chipset under Windows ends with a failure (eg. Error 20: Management Engine Device not present, or something similar).
Due to the lack of the ME several ports on the board, including all M.2 ports aren't working, booting OS works only on USB. So it's now other way, as to program the chipset with a ME.
Usually on ASUS boards it worked... -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
Troubleshooting Attempts:

Sorry for creating a second post, I didn't understand how to fix the error in the message. I need help, laptop ASUS P1412CE (P1411CEA-EK0395X) SN: N4NXCV033901146. There was a failure during BIOS flashing, and the laptop stopped turning on. The original, non-working BIOS is attached. Unfortunately, I was unable to correctly generate the BIOS from what is presented on the Asus website. Help me make a dump. Thank you....
