[mximiliandz]

Good morning, gentlemen, I hope you can help me with my laptop, I told you that I saved it about 2 years ago because it wouldn't turn on, now I have a ch341a programmer, I made a backup of the bios, I flashed an original downloaded from lenovo and it started, but it turned off after a few minutes, I entered the bios configuration and the brand, model, serial number, windows serial number, etc. did not appear, I request your help, I did everything I found in the forum but I could not solve it, also now it won't start again, it turns on but the fan does not turn, I will share all the information I can, yes, it does not have the back label but there is a QR code in the front to directly enter support, so I have almost all the information, greetings and thanks in advance.
Brand : lenovo
model: ideapad s145-14iil type 81w6
serial number: PF2MNE4B
Processor: Intel Core i3-1005G
memory 4 GB RAM integrated into the motherboard

I attached the backup of my BIOS, be careful with this BIOS the laptop turned on, but did not boot, only the fan run, and a photo of my motherboard
Thanks
P.d. I had forgotten to give you this information, the bios chip is a Giga device 25B127DSIG which I have not found in any program the exact model to flash it, I have done it with several models the gd25b128, db25x128c, w25q128b, c, vj, etc and nothing has worked for me.

Thanks Volinakis, from the file name I assume it's the original BIOS.
Downloaded from Lenovo's website, right? Unless you modified it. If not, I've tried it. The computer turned on, but it didn't show any information, such as the model, etc. Then I installed other ones, and now the laptop only runs with the fan. I haven't found any software, as I have the exact same BIOS chip model as my motherboard. What would you recommend flashing it with? Thanks for responding so quickly. Best regards.

I'll try it right away. Another question: is it necessary to flash the BIOS directly, or can it be flashed with tweezers? All the tests I've done have been performed with tweezers. Could this be my mistake? Thanks again.

I apologize for not responding to Mr. Volinakis, but I just finished my work. I'm self-employed. This is why when work comes, you have to do it because you can't be sure that more will come tomorrow or the day after. So, I'll try the BIOS now. Thanks again.

Hello, good morning. I haven't responded since the last message I sent. I was tasked with repairing my laptop. I'd like to tell you that the BIOS you provided me works, but only halfway. I'll go into the step-by-step instructions.
1st - If it turned on, it only entered the BIOS and got stuck. I'm saying this because I connected another keyboard.
I force-restarted it, and then it turned on fine, but since it was disassembled, I didn't have an HDD to test it. I spent several minutes pressing keys and it did work. So I turned it off. I put in another RAM, a blank SSD that I had saved, and whoooooooooooo, it didn't boot anymore.
I removed the RAM first because this PC has 4GB built into the motherboard.
Then I removed the SSD, and nothing.
It won't turn on again.
The good thing is that with the flash you shared with me, when I entered the BIOS, it was almost 0. information, I will attach a photograph, thanks again and I hope you can help me, greetings.

bios is extracted from update and transferred your DMI. Check hardware problem, bios is ok.

Thanks for answering again, I had already done the transfer of the DMI to the downloaded Lenovo BIOS by looking at the information on how to do it here (as I said before, I informed myself and tried to solve it myself before bothering you, in the same way my idea is to learn and thus not bother you or depend on you, in the same way I want to ask you a couple of questions
I read the same here in a post from a user who had a similar problem, and he said to solve it by deleting the BIOS file header, this would be starting at position 00000000 to 000007F0, and voila it works, my question is the following, I suppose I can do this with an editor like HxD, being that way this information should I replace it with 0, with F, because if I delete it assuming the size of the BIOS changes
the other thing is that I cannot find my exact BIOS model in the programming software, I have also seen that they say that to program it I can choose between these

Flash chips in VSCC table:
EF4018 (Winbond W25Q128)
C84018 (GigaDevice GD25x128)
C22018 (Macronix MX25L128)

Wear:
"GD25B128B/GD25Q128B"
P.d.
I also saw that the header could be removed with ueffitool, I downloaded it and opened my original BIOS file, but the Capsule option doesn't appear in actions. Does this only work with BIOS in .CAP format? Or am I doing something wrong? Regards
