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... -
Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.

The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6... -
Hi ya folks,
I have this MacBook Pro A2485 (M1 Pro 2021) which came in for repair.
It had a shorted SSD power supply chip. Therefore it was stuck at 5V.
I replaced it and the SSD are fine. No more shorts.
But The mac still pulls 5V and 200mA. If i leave it alone for 5 mins, the mac manages to receive 20V and 40mA. Of course, which doesnt mean the mac starts after power meter reading 20V.
But while the mac is stuck at 5V, i checked the board with thermal and found this chip was trying to start. Chip picture is attached.

This chip is shorted thru. Based on what I see, it's either a 3.3V or 5V buck converter, just my guess. The markings on the chip state "S2=AB".
A photo of the chip is attached.
Thank you....
