Hi, Im trying to find the area on the chip that contains all of my laptops information, but I havent found it. The laptop won't turn on anymore. I was updating the BIOS, and it was supposed to reboot itself, but it wouldnt turn back on. I ve tried every possible solution, every alternative on Lenovo forums, everywhere; I ve taken it to technicians, and no one has been able to fix it. I've already read the chip that contains the BIOS (Winbond 25Q128JSVQ) and searched for my laptops data, but they're nowhere to be found. I only find scribbles and lines of text indicating errors. Has anyone had a... -
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... -
Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...06-17-2025, 07:17 AM

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -
Hello, friends
I have one not working graphic card (Asus Rx 470 mining), which I am trying to repair. There are two chips which I am reading clearly but can't find anything about them. Google just says nothing for both of them. One is AMCH675 and the other one is 71630VSW. I tried different variations of tipping but without success. I am uploading a photo for each of them. I will really appreciate if someone can help....
Thanks...
