IdeePad 5 15ALC05 bios please!

Hi,

The LEDs are on and there is a black screen.
I tried to upload the bios from thread #5 but no effect. I have a request for the correct BIOS with my DMI. Original ripped bios attached.

Lenovo Ideapad 5 15ALC05 , HS553 MN-D701 Rev 1.0 Rayzen 7 Black Screen.

ok, I edited that file now and pasted all that unreadable decrypted stuff from my backup to the virgin bios. Now I can upload it to my bios chip right? Do I have to click on that in my asprogrammer?


And I just copied everything in a range from 1000 to 2FF0 from my bios to the virgin bios. The start on my new created bios is just empty FF everywhere is that right?

yes, you can write the bios chip with the newly edited content..I haven't used that program and CH341A..I don't know to tell you anything about it..

Ok, so I select the hex values from 00001000 to 0002FF0 (there is no 2FFF) and copy all that in the file from your post#54 (h2cn31ww.rar) even though I can't read anything there right?

the text says this:

"LENVk������� ¦O†Mm*gKš@ôÑŽÍè \^Ë`_Eƒ‘-¢J

[...]"

well, there's nothing to read there, because it's empty, the bios being virgin...yes, you have to fill that empty space..

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)

try the bios from post #55, there is also the interval where the DMI information is found, use the HxD program (you can find it for free), enter both bios into the program, select the interval in both bios and pass the interval from your bios to the interval from the bios from postl#55 (copy-paste), that's all..

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?

[SMDFlea]

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:
https://www.winbond.com/hq/product/c...artNo=W74M12JW

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...
