I did the same as you instructed and reprogrammed the BIOS But unfortunately the delay display and high fan speed still persist In post number 36 I said that this laptop had a problem with the graphics chip and after reballing the graphics chip, I programmed the BIOS and this problem occurred. And the Nvidia graphics are still not recognized. Is there a solution?... -
A new issue that my client has just informed me is that the laptop's graphics chip was previously damaged and they reballed it, but unfortunately it is still not recognized and in fact only the Intel graphics are recognized.
The question I have is whether this could be the reason for the display delay and whether it is possible to make a change in the BIOS file to resolve this problem.Leave a comment:

I re-programmed this file and this time after turning it off and on a few times, the laptop display. But it still delay display and the fans are spinning too fast. The point is that no serial number or MTM is displayed in the BIOS and it is invalid....Leave a comment:

hello
i have lenovo ideapad 3 gaming 15-imh05 (gy530/gy531/gy532 nm-c871)
The problem with this laptop is that the delay display and the fans work at high speed after a few moments
I realized that I need to edit the device serial number in the BIOS dump.
And you said bios+Dmi
I wanted to send you the dump file I have and the device serial number if possible and you can do it for me.

There is no pu8501 in my pcb
I have attached a photo of it for you
However, the voltage of its pins is as follows:
1= 0V
2= 0V
3= 20V
4= 0V
5= 0V
6= 0V
Resistance of pin 6 to ground = open circuit
Resistance of pin 1 in u4503 to ground = 10MΩ and increasingLeave a comment:

Dont work LCD display Asus zephyrus s15 gx502
Hello Friends
I have an asus zephurus s15 gx502 laptop, unfortunately I don't have a display on the laptop LCD, but it works fine on the hdmi
This happened when the battery socket was damaged during removal.
Now the voltages I have are as follows
+3VS_LCD_OC is activated at the moment of turning on the system and quickly turns off
And on the pins
LCD_BLEN_CON
LCD_PWM_CON
I have no voltage even at the moment of starting.
In addition, the LCD cable is also healthy
No activity results to display
