Bios + DMI (serial number etc) .

Hi SMDFlea,
i tried flashing using the attached file, but the screen remains black with no Lenovo logo.
On the first power-up, the fans ramped up to maximum speed for a few seconds, then the system rebooted-still with the same issue.

Bios + DMI (serial number etc) .

Update
4 hours later and without battery, the pc turned on.
After a couple of boots it went back to black screen again.
Pls help me

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.

I programmed this file, but unfortunately the laptop turns on and doesn't display, then after a few seconds it resets and still doesn't display.

it's the bios on the site... maybe you wrote it with errors... try again...

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

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.

[b.rakhshani70]

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.

the bios from post # 30 is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

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?
