It was the capacitor just below and Left of the number 17 written by the ITE chip.
I typed into google: 'super io chip getting hot'
And the first result was here:
https://www.badcaps.net/forum/troubl...-super-io-chip
The suggestion was a shorted capacitor. So I pulled out my multi-meter and sure enough shorted. Carefully popped it off with my flush cutters (It cut through the solder on one side. but the capacitor cracked on the other pad.)
The motherboard LED lights came on when I re-connected the power, and it booted straight away.
Lesson to me, don't buy and re-solder the chip as a first resort (I'm only out the $12 for 2x vacuum SMD tools and the chip, so it's not awful.)
Just looked it up, I spent $9.82 for the motherboard đ. Even with new tools I think a deal!
The heatsink was $15, which is also fine đ¤ˇđź, it's white to match the case.

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 all,
As the title suggests, how can I be sure that my EC chip is really dead?
I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.
Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard... -
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 ?

Hi all., I am working an ASUS TP412Fâ., motherboard Model TP412FAC R: 2.0. The problem I am facing is the 3.3 buck converter (L8=7J RT6256BGQUF) gets very hot when 19v is applied through DC-in jack. I don't think Schematics or Boardview is availble for this model. The chip get so hot that I can't even take the voltages of the pins. I replaced the chip but the problem is still there, new chip even gets very hot. The input on pin 5, 19v is present. So I removed the Output coil & the chip & checked the voltages on the chip pads which are as below: Please view if any volts seem to be abnormal....
