Can someone share the boardview for Asus Pro WS X570-ACE ...

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...

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

Hi everyone,

I'm dealing with an intermittent problem and can't find a solution. Sometimes my notebook starts up and everything works fine. However, after I turn it off and try to turn it on again, the motherboard starts, but the screen stays black. It seems like the notebook freezes and a green LED with a light bulb icon stays on.

If anyone has the service manual or any suggestions on how to fix this issue, I would greatly appreciate it.

Thanks in advance!
