How to transfer information from one BIOS to another?

03-04-2025, 03:41 AM

Hi.
I am starting to learn about UEFI BIOS.
At the moment I have Lenovo laptop with bad BIOS.
I tried to clean ME region and transfer EC region from a known working BIOS, but the laptop does not POST (just fan spin).
So there is something else bad.
If I flash a know working BIOS, the laptop POSTs and boots into Windows.
But the problem is, that the serial numbers, Windows key, and every thing else is from another laptop.

Where do I start to transfer the S/N, Windows key and other information from one BIOS to another?

Thank you.

Hello,

I think it’s not the right forum section you have a dedicated section related to bios.

You have to copy DMI informations.
Location dépends Of the brand/model Of laptop.

For Windows serial search in hexa :

010000000000000001000000000000001D000000

you can read that too:

ASUS TP500LA BIOS request/repair/merge?

by jbonavita

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized

Things I tried

1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request

by Wahaz

Hello,

I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.

by Bloodhoundje

Hi everyone,

I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

I have desoldered the bios chip (GigaDevice...
