ASUS M5A78L-M USB3 rev 1.01 Not power. Suspecting ASP1003QGK
Hi.
I have ASUS M5A78L-M USB3 rev 1.01.
The power supply didn't work. I have changed it to another one.
Main responds on the button. The power supply starts up.
P_VCORE_EN, comes to ASP1003QGK-C, but PU1 (PWM power supply to the processor) does not start.
HUB SU1 SB710 (A14) FCBGA528 AMD 218-0660017 receives only one 1.2V supply. Doesn't start and stays cold.
SPI, has all voltages risen but there is no exchange.
Power sequence stops at step 10.
At the same time, NU1 RS780L FCBGA528(HDMI) AMD 215-0674058-00 receives all power and heats up.
CLOCK...

Hi.
I have manage to find the problem.
In my case missed exchange between CPU and U7200.
CPU_VIDSCLK
CPU_VIDSOUT
These lines have 1V, but without any commands from CPU.
CPU_VR_READY was high.
I cleaned the main in a ultrasound bath and reflowed then the processor.
Main starts.
However I must reball the processor.
Thank you everyone.

Macbook A1466 820-00165 resets every 10 seconds
Hi,
It have had a problem with U7100 and short circuit in Q7130.
I replaced them.
It starts now and waiting 20 seconds and then starts to reset [B]PM_SLP_S4_L [/B]every 10 seconds.
Almost all voltages rising
except U3090 and U3210 (LED) - not receives enable signal.
U4500 is trying to rise - receives enable only 2-3 seconds
Here is my measuring of important signals.
What else could be the problem?
I need to help.
Thank you an advance.Hi,

Re: Asus X550V (X550VX-XX057D) bios Request

Re: a1708 emc 2978 820-00875-01 bios
Thank you so much!
You even put my serial number, you are very generous!
But importunately new BIOS gave my nothing.
Probably it has another kind of problem.

Re: a1708 emc 2978 820-00875-01 bios
They are different:
From the bottom cover
C02VLAEGHV22
From the SPI
C02T836XGY25

Re: a1708 emc 2978 820-00875-01 bios
Hi,
I have A1708 EMC 3164 and main 820-00875-A
(I guess this main is from A1708 EMC 3164. It came from another service).
SPI was not soldered. And Main have had other traces of soldering and lack of elements.
I restored everything.
All powers start exclude backside lights. Probably it is SPI issue.
I used SPI dump from topic number two.
I am watching SPI request and answer every 6 seconds.
It is not correctly.
(By Mistake I have used BIOS from 820-00840-A main before - I saw...Last edited by AlexVG; 06-28-2023, 12:39 PM.

Re: A1708 820-00840-a efi lock
I can suggest what was before:
Somebody had tried remove the EFI lock before me. But had got the same results.
Probably he put wrong number, or would rather didn't change it.
Number in the SPI was C02TK51HHF1P
But on the bottom cover is FVFXQEK7HV29.
What do you thing may be different number cause of problem?Last edited by AlexVG; 05-30-2023, 05:10 PM.

Hi,
Thank you.
But something goes wrong.
Doesn't want to run the screen.

In ME Analyzer i have got the same problem:

Below is my previous dump that I read after turning on.
It works but asks password....Last edited by AlexVG; 05-30-2023, 04:31 PM.

Re: A1708 820-00840-a efi lock
Hi,
A1708
EMC 3164
Main 820-00840-A
I had problem with running.
I have checked SPI and found out this problem:
Detected CSE Extension 0x03 with wrong Partition Hash at FTPR > FTPR.man!
Then I took ME Cleared DUMP here, replaced Serial number.
Everything is running but I get EFI password request.
So, EFI is blocked.
Would you like help me to cut the password request please!
Here is my original DUMP and good dump.
Thank you....

Re: Asus X550V (X550VX-XX057D) bios Request

Re: Asus X550V (X550VX-XX057D) bios Request
Thank you.
It's running but found out another problem:
I replaced HUB on ASUS main MB1504 (201) X550VX with i7.
And put RTL8821AE wifi module (I attached it. It is ANATEL Combo module) from the same MB1302 (202) X550VX with i5.
But it works only in BT mode. MAIN cannot recognise it at all.
So, mainboard with i7 processor wears different wifi module (only brand) but with the same RTL8821AE cheap. (I attached it. It is as a AzureWave AW-CB161H module)...
