A1466 Bios Cleanup ME
Hi all,
I am working on a Apple MacBook Air A1466 820-00165-A logic board. The BIOS got corrupted or shorted because I have fan spin and all voltages are there, no chime or boot.
The BIOS probably needs ME cleanup and serial change to C1MRTUDZH3QF. Please help...Last edited by BrandonJL; 05-12-2022, 04:55 AM.Comment

Re: macbook air 820-00165-a bios
The serial has not been changed, it is the same as serial you posted, CRC32 is valid, only cleaned out the ME Region. Report back if successful.Comment

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... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
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.... -
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...
