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... -
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, first of all, excuse me, I am using the translator, English is not my native language.
I have a Lenovo ideapad 330S - 14IKB laptop.
The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a... -
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 ?
