IdeaPad 5 15ALC05 bios please!

[thesumate]

I got the programmer and read the bios of my 15-alc05 now. My Bios chip is called "74m12jwsiq" but asprogrammer automatically suggested "W25Q128FW". What do I have to do now? How do I add that DMI info and what is this? is it necessary? Here is my bios backup (i have packed two files into the folder on one I just clicked save and on the other i added .bin when i saved it)

Hi all.
Got a 15-ALC05 here with a black screen / power light. BIOS dump attached. S/N is PF2YAA43
I'm struggling to transfer the DMI data across, have tried a couple of the attached BIN files from this post but no difference.
Could someone kindly provide me an edited file (and ideally the location of the DMI data - I'm reading it's 1000 - 2FFF but not sure if that's accurate for this dump?)

Thanks in advance

try

Ok, perfect! I just wanted to make sure it's working for my chip before I buy something. This programmer is fine? https://www.amazon.de/EEPROM-Program...ustomerReviews

And I can basically use any ch341a programmer software right? Or should I use a specific one?

ok, if i select this chip "W25Q128FW". I can read and write without issues event tough my chip is called "74m12jwsiq" ? So I can write the bios from lenovo website right on it and then it should work?

Make a backup and post it here.

Choose W25Q128FW manually from the chip list

I downloaded multiple programs now but I can't find my chip in any of them. What do I have to select instead now? What could go wrong if I select another chip so read another chip?

Alright thank you very much!!
"get a chip from the database equivalent to what you have in your laptop", so do I have to look for a chip that's available in the software with the same properties as here:

yes..yes.. but try the two programs, maybe you have the chip there..

Ok perfect. But I can't find this chip in the software for the spi programmer. This chip isn't listed there. What do to? Or do I have to get another program?

use one of these programs.. if you can't find it, get a chip from the database equivalent to what you have in your laptop..
don't forget to make a copy of the original bios before writing with new content..

Ok, so on the front of the mb there is nothing but this one chip that looks like it could be a bios chip. Since this is all over this laptop model, does anyone know where its located? The back of the motherboard also has some sort of shield on it and I dont really want to unscrew it and take that shield off.

EDIT:
I removed the board now and also looked on the underside under the shield thingy for possible bios chips but there weren't any chips at all. The only one that looks like it is the one from earlier called "Windbond 74M12JWSIQ 2112"

Winbond 74M12JWSIQ is the bios chip...

Okay, thanks so I'll have to get such a programmer. Is this the bios chip? It says "Windbond 74M12JWSIQ 2112". I don't have that programmer yet but I already downloaded its software. I couldn't find this chip there. Is there another chip on the other side of the board so I have to take the laptop apart? Or is it the right one?

Hello, i'm very new to all this. I also have this laptop "Lenovo IdeaPad 5 15ALC05" wich doesn't boot (screen is black). What do I have to do to flash that bios chip? I don't know anything about all that and would be happy for some information or resources (:


"Winbond 74W12JWSIQ"
is this the bios chip? The 'W' could also be an 'M' I think.
