Looking for Diagram/Schematic for Asus VivoBook.

Hello. I got an Asus G512L which doesn't start, from a day to another. I manage to make some measurements on the mother board and got to a an IC ( AYK M16 879 ) witch has 19V on the one of the pins ( i assume is the input ), no voltage on the output coil ( output to gnd = 36.3ohm) and 3,3V on one of the pins ( i assume is the enable pin for the IC). Based on all this investigation, without any datasheet of the IC, i think that the IC (AYK M16 879) is dead. Does anyone has any idea what this IC is or how to proceed with the investigatio/repair ?
I put also some pictures with the IC....

Hello everyone,

I am looking for the ASUS Q500A BIOS version Q500A.208.
The original ASUS update file name should be Q500AAS.208 or Q500AAS208.CAP.

My laptop currently has a corrupted EC firmware and it will not accept downgrades to 205 or 207.
Because of this, I specifically need the full dump or update file for BIOS version 208 from a working Q500A.

Motherboard: ASUS Q500A
BaseBoard Version: 1.0
Platform: Q500A / P55VA family

If anyone has a working Q500A and can provide the full BIOS dump (including EC region), or the...

Requesting Boardview and Schematic for Asus Zephyrus M GU502GU-ES003T(GU502GU). I searched online but didn't manage to find anything, at least not for free.

Additional Information from msinfo32

My Laptop isn't working, and everytime I'm running out more and more of possible explanations for what's causing it.

I already wrote a post explaining the problem a bit in detail in another thread. My computer freezes at random times throughout the day somtimes, and then it reboots. It all started after I replaced the previous motherboard which burned, for a new motherboard.

MemTest86 gave me good results, seriously, help anybody at this point, I would accept the answer that goblins live in your Laptop...

I've been dealing with so many complications for months, trying to find and then fix the root cause of the issue I really need help and I have to solve this on my own (Going to Asus headquarters isn't an option for me. First, because I'm very stubborn and want to insist that I can fix this sort-of-myself somehow, and second, the location is too far away for me anyway).

Right now I'm desperate trying to put an end to this nightmare, but OK, I'll do my best to be somewhat brief in explaining and relating the entire situation and context.

Hi,
I'm having difficulty figuring out how to get a working and properly sized bios for an Asus Zenbook UX425JA. The bios from Asus is 16.25 MB, whereas the XM25QH128A on the motherboard - which I am attempting to program with a CH341A - is 16 MB in size.
SN: L833NBLP0002CXMB
Thanks.
The bios from the website can be found here:...

Hey guys, I have an Asus gaming laptop. It arrived with a short circuit on the 20V rail due to a failed attempt to restore the backlight. I resolved the short circuit, but when I connected the charger, the laptop wouldn't turn on. I also noticed overheating on the 3V and 5V power supply. After a few hours of diagnostics, I identified the faulty component: the IT8308FN, it seems to be a GPIO expander for EC. This component got damaged and caused a short circuit on the 3V LDO rail, causing the power supply to overheat due to the overcurrent.

My question is: is this IC reprogrammable,...

Does anyone have a schematic or boardview of the Asus UX5401EA R2.2?...

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...

I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.

You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.

Also, I uploaded a backup file for the bios that I extracted by using CH341A...

Hello everyone.

I am here to ask for help identifying a problem with an Asus Rog G513qr, Ryzen 9 5900x and RTX 3070.

The laptop turns on but turns off or freezes when connecting a USB flash drive (even during the ROG logo). Even without using the USB ports, the laptop is unstable and when the charger is disconnected, it freezes.

A few months ago, the laptop started freezing when powered only by the battery and in power saving mode.

After replacing the NVME disk and replacing the liquid metal, thermal grease and thermal putty, it got worse and...

Hi everyone,

I'm having a serious issue with my ASUS Zephyrus GA401I (4 years old, worked perfectly until recently). The system is lagging heavily, even in the BIOS, and is charging extremely slowly (a few percent in hours), making it nearly unusable. I suspect a motherboard or power delivery issue.

Symptoms:

• Severe lag across the system, including BIOS navigation.
• Slow boot times and unresponsive performance in Windows.
• Battery charges very slowly (e.g., ~5% in 2–3 hours).
• No error messages or BSODs, just extreme sluggishness.

What I've Tried:

• Replaced

Hi,

I have a new Asus Zenbook S16, Model UM5606. Unfortunately, the keyboard backlight is too bright, even on the lowest setting. I have explored several ways now:

- kindly ask Asus for an adjustment - they basically told me to STFU and get lost It is not possible, they say. Of course.
- tint the keycaps from behind - I have already tried that - it is kind of a last resort
- try to find out, how it is done, look at schematics - this is, where we are at.
- maybe get the BIOS modified somehow? This would be the best option but I do not know a lot about...

Asus F512D, motherboard X512DK MAIN BOARD REV. 2.1 Hynix 4GB OnBoard, (ID0=0, ID1=0, ID2=1)

In this case to disable onboard ram, Take out R0916 and place a 10K Resistor on R0913.

The configuration would be for N/A:N/A , ID0=1, ID1=0, ID2=1. (Working for me with Hynix 4gb OnBoard Memory, in this case, do not touch other resistors)

Hi guys,
Schematics and boardview (PDF sorry) for those who have to fix this big motherboard.
Best regards...
