Hello guys, i am repairing a motherboard for Asus UX581GV and i found that the EC chip is dead. It is IT8225VG-128 and i guess it needs to be programmed for this model exactly, but i know that some of those programmable chips get programmed automatically on first start of the board from BIOS chip. So, my qustion is, does somebody know if that is the case for this laptop or if not, does somebody know somebody from which i can buy it and have it programmed for this laptop exactly? Thank you. -
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.

Hello everyone,
I'm trying to flash the BIOS chip Macronix MX25L6445E from my ASUS X455LD laptop using both a CH341A and an EZP2019+ programmer, but I keep encountering issues.
Reading the chip works perfectly, and I can extract the BIOS dump without any problems.
However, erasing and writing fail every time, regardless of the software I use. (Neo, asprog, ch341, etc)
I also tried applying 3.3V to pin 3, but it still didn't work.
I attempted to unprotect the chip, but when I read it back, the registers remained unchanged.

Hi
I try to repair a asus Asus X571GT (DA0XKTMB8C0) no power no lights.
I saw a burned (small hole in it) chip (JW10F) proberly a TPS22976DPUR, I removed it, now with power connected the laptop turns on and direct off again, power led and fn will light up.
I found on a donor lenovo board a G2898KD1U (wa9y), looks the same ..
Result is still the same, turns on and direct off again, first attempt is with backlight on all other direct attempts are only the power and fn led.
Could it be the chip is to diffrent to make the laptop work again ?
