I already did all that soldering and I have it ready but I don't know what BIOS I have to put in it and all the details, my serial number and other details are these lenovo IdeaPad 3-15ALC6 - Type 82KU Serie:PF48CFZ2...

Hello everyone, I need help with my Lenovo IdeaPad 3 15ALC6 - 82MF0004BR motherboard nm-d521 rev 3.0.

I downloaded the BIOS GLCN66WW released on 02/19/25 directly from the Lenovo website. After installing the firmware update, the notebook stopped working. It turns on the Capslock, NumLock and ESC, show backlight on the screen, and then restarts and stays in this endless loop turning on and restarting.

I was able to successfully extract a backup of the BIOS using an EPROM programmer. Could someone help me revert to a previous BIOS? I don't know how this DMI thing work...

Schematic and boardview...

Hi,

As the rest of you here, I'm getting no screen output, caps and Fn-lock led's working and power button led flickering. Holding bios recovery button or novo button (small hole next to power led) results in two short beeps and nothing else.

Hi all! I am new to Badcaps and I've got my Lenovo ideapad 3 15ALC6 bricked as other many users ...

Hi.
My Lenovo did not start and stopped giving video. I removed the Winband 74M12JWSIQ chip and the programmer shows it as W25Q128FW [1.8V]. I made a backup copy of the BIN but I can't find a BIN that works.
Can you repair the copy of the BIN file?

Hello,

I receive two board like this last weeks ~ same symptoms:

I finally think the blinking of the power button is not important, maybe caused by the battery discharged or absent. (test with the battery, the blinking may stop)

I 'll recheck these board by the end of the week and i'll tell you if i found something.

Hello friends,

I have this laptop AMD Platform starting & not posting, fan spinning.

When i press power button, the board get almost immediatly 0.5A ~ and board get stuck at 0.5A with power button led blinking indefinitly.
If i stop the computer (pressing 5s power button), board stop and when i restart i get approx 0.37A ~ and


I try to reflash the bios with no luck, same result, and i try disabling onboard ram (i remove resistors accordling schematic), no more progress.

CPU and his area heat, maybe the cpu is dead?
...

Hello folks,
I have a Lenovo Ideapad V15 G2 with a Ryzen processor.

The owner damaged the motherboard with a knife while cleaning the ventilation slots on the bottom.
Pretty strange, but that's how it is.

I patched the 5 traces he cut.

The notebook now starts again, but does not produce any images. Neither via HDMI nor on the display.
But the display turns on, so it has its operating voltage and also 3.3V.

What signals does the display use to get the image? Unfortunately I have no experience with this.

Schematics:​...

I thought I had included the boardview and schematic.

BIOS was corrupted when updated on both models !


I loaded the Lenovo V14 G2 ALC model from the old bios backup and the DMI information came to its place without any problems, but unfortunately I had to load the DMI informations of the Lenovo IdeaPad 3-15ALC6 model from another copy.
Since I do not have an old BIOS backup, I cannot enter the original DMI informations.
