Hi all,
I've Been repairing laptop for a couple of year and this my first attempt at replacing a cpu.
I use a lenovo yoga 9 14itl5, the cpu is tested and working before it being transferred to a different yoga 9 14itl5.
I've clean the Me but nothing else, wondering what Bios modifications need to be made.
Right now The board is definitely on because I got -PLTRST but it doesn't boot to bios

Summary of BIOS Whitelist Removal Problem
Problem:
I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
Initial Findings:- My current BIOS version is N1KET58W (1.45).

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.... -

I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!

Good day, everyone!
I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.
I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the...
