What you need is not whether you have a spare bios but you need to buy an SPI programmer especially if you don't have the serial number.

*****************

Hello, good evening, dear engineers.

My board is an HS461 HS561 HS761 nm-d521 rev 2.0 - from an IdeaPad 3-14ALC6 Laptop - Type 82KT.

I appreciate any help.

The problem arose when the battery died completely due to my carelessness.
When I started it, I inadvertently shut down just as the Lenovo logo was loading.

I tried every method I found on the web and in forums. Forced reboot, clearing residual power, disconnecting the internal battery. Nothing worked. Then I bought the ch341a programmer and used a clean copy of the BIOS update.
GLCN63WW using the UEFI TOOLS tool, I extracted the raw file from the body and followed the steps in other forums with the programmer to read, clean, erase, program, and verify the process.

It still doesn't work.

Unfortunately, I didn't create a backup of my original BIOS due to lack of knowledge.

I don't know what else to do. The laptop turns on the power button light and stays that way indefinitely.

And if I disconnect the internal battery and the BIOS battery and press the power button, the LED keeps blinking indefinitely.

Please help. I think this forum is the only hope I have left.

you have everything you need at post #52..

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...l=ThisIsHow

Hola.
Buena noche.

O sea que solo con el archivo glcn52ww.bin podria revivir el portatil?

No nesecito preparar el archivo bios como lo he visto en otras entradas?

Por favor una aclaracion.

Recuerdo que lastimosamente no pude salvar el archivo original.

Hello.
Good evening.

So, just using the glcn52ww.bin file could revive the laptop?

Don't I need to prepare the BIOS file, as I've seen in other posts?

Please clarify.

I remember that unfortunately I couldn't save the original file.

write it as it is...if you write it correctly and the problem is from the bios it should work...
