Re: Mac air a1466-820-00165-a-lock
if you wanted to delete your password this is what you need ... I think you wrote the bios with errors ... don't use the clip as it gives errors..remove the chip from the motherboard when you write it or read it or paste threads between the programmer and chip..after doing a PRAM reset ..Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

Re: Mac air a1466-820-00165-a-lock
Find one with clean ME firmware, use the forum search https://www.badcaps.net/forum/showth...A1466+EMC+2925 .You will need to edit in your own serial number thats on the case, and correct the fsys checksum ,see the video linked here

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Good day folks. I got a project on hand and would like some thoughts on whether it's possible to achieve, albeit impractical. You know me - I like to over-complicate stuff
The setup: I got a Paradox EVO192 alarm panel, a serial-to-ethernet adapter and an official PCS250 GSM communicator.
The task (TL/DR): connecting both the ethernet adapter AND the communicator to the single serial port of the Paradox panel. Connecting their TX/RX lines in parallel the data would get all messed up. At the very most, I THINK I could parallel the RX pins of the ethernet adapter... -
Hi,
had T490 with faulty bios chip. Bought chip out of ebay and soldered on. Laptop starts and works however serial numbers of laptop and motherboard do not match.
I have updated laptop model number.
1) I did not find the way to update laptop serial number - I have this one.
2) I dont know where to get my motherboard serial number and how to update it. Is it somewhere physically on the mainboard? How do I update it?
Hope to find someone to help me with this as I am hitting dead end at the moment.
Many thanks

Hello, I have problems with the BIOS password of my Dynabook C40-G-126, with motherboard IP3_CN16S_MB_V20_20201229B, I would like to change the BIOS to be able to change components because it is limited, it is the PYS26E with serial number 41100104H. I have searched the forum and there is a ".bin" file for my motherboard, but I don't know exactly if the serial number does something because on my device that ".bin" does not work or at least it does not remove the password.
Thank you very much in advance for the help, I will keep you informed
