Re: asus x200ca need to identify this chip
what do u think is the factor if the system completes the boot process if i detached the X200ca IO board from main board and plug the adapterComment

Re: asus x200ca need to identify this chip
now that i shutdown the system using windows process (not through power off button)... i could no longer power on the main board with isolated x200ca IO board if plug the adapter. It seems the hardware demands for physical power on process which i think defective or is it due to faulty bios since before that the system wont POST unless i detached the IO board.Comment

check all parts on the IO board,resolder all parts.Check the IO cable for damage .Comment

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... -
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... -
Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
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... -
This is found between the usb-c port and processor of a Asus ROG Ally Z1 Extreme. I cannot find it anywhere on google. Please help me identify.... -
Asus Vivobook 15 (board X513ea R2.0) gone dead when user plugged an iPhone cable into the USB-C port during boot. Now there's no LED light, no power at all. I checked all MOSFETs and capacitors, no shorts found. The board only has 3.3V and 5V present, no other voltages.
I injected 3.3V into the EC chip power rail (ITE IT5125VG 128), and it draws 80mA, while the 3.3V LDO chip RT8249C has a max output of 100mA. I checked the boardview and found there are only two chips on this 3.3V rail, EC and Realtek audio chip. So I think EC could be the problem.
I found the EC chip...09-14-2024, 02:09 AM
