I was thinking about how to run [B]Boardviewer[/B] in Linux but suddenly I spotted this brand new [B]FlexBV FREE Edition [/B]in searching result. So I decided to give it a try. Many thanks!
What is interesting that the program shows a PCB back side (.fz). So every time it's necessary to flip and mirror (the same is in the OpenBoardView). Is there a workaround or an option in the settings to show the front side at once?I was thinking about how to run [B]Boardviewer[/B] in Linux but suddenly I spotted this brand new [B]FlexBV FREE Edition [/B]in searching result.

That's right. Download from ASUS site or dump the BIOS and then unpack the image using UEFIExtract. Choose old versions of UEFIExtract. Next, using your favorite tools find in the folder all files of 64KiB or 128KiB size precisely. A hexeditor helps to compare iROG chip dump and those chunks. Because ASUS BIOS doesn't hold all necessary parts of iROG firmware.

Richtek Date Code YMDNN
I didn't find how to decrypt the date code but I googled a little bit and I think the years are encrypted like this :
from 2010 til 2013 - letters from C til F
from 2014 til 2022 - numbers from 1 til 9
I hope it may be useful in order to avoid bad batchesLeave a comment:

It doesn't matter there is 5vduals or not. 5vduals is controlled by SIO that looks start conditions. Find in the repair guide section #3 "POWER ON SEQUENCE" and check all steps from 1 till 9. I mean to measure signals that are figured in these steps. Also a motherboard won't turn on if 32kHz crystal doesn't work....Leave a comment:

Hi. There's the repair guide for a similar asus motherboard. Try troubleshooting it step by step using the power flow and the power on sequence diagrams.
Good luck!

Yes, I did. G1610 is working for sure but the board behaves the same way.
Finally I've found an option in BIOS settings that can mitigate the problem a little bit. It's a GPU voltage adjustment. It allows to set VCCGFX voltage manually. If I set it into 0.8v or 0.9v the mainboard loads OS normally (no freezing).
I guess a PWM controller of CPU VRM is faulty. But haven't replaced it yet...Leave a comment:

New observation:
With a discrete PCIe graphics card as main graphics the mainboard + Ivy Bridge CPU are getting boot.

Asus H77 LGA1155 mainboard stopped working with Ivy Bridge CPUs
Bad symptoms when Ivy Bridge CPU (3rd-gen 22nm) is installed:[LIST][*]Won't boot OS (just blank screen or stucks at asus logo, monitor is turned on) with hangs at debug (post) code A3;[*]USB stick with MS-DOS can be loaded via F8 boot menu;[*]Other OSes won't load - hangs or goes reboot;[*]Postponed for several seconds reaction to Alt-Ctrl-Del, Reset and Power buttons;[*]An operating system starts loading but won't finish if it's left only 1 CPU core in BIOS settings;[/LIST]What I've already done and it hasn't helped:[LIST][*]Cleared CMOS many times;[*]Flashed different versions of BIOS in a CH341... -
Re: Lenovo Y540-15IRH internal graphics problem
Recently I tried to switch the graphics again. This time the LCD panel was connected. And it was the same - black screen, no booting. No luck. When I disassembled the laptop I saw a strange spot on a CPU die and a corresponding spot on a heat-sink without thermal grease. I remember for sure that the last time thermal grease was covered evenly all the CPU die. I suppose a local overheating could cause such defect.
The resistance of VCCGFXCORE to GND is about 0.5 Ohm. Is it too low? I guess internal graphics is fail. So I flashed...Leave a comment:

Re: Asus P8H67-M LE Rev3.00
For sure it worth to backup and then flash BIOS chip in a programmer.
Although I bumped into such problem once. If resistance of every power rail is OK then SIO or PCH might turn the system off. Oscilloscope with 2 inputs can show which chip should be blamed. In my problem PCH appeared to pull #SLP_S3 down earlier than SIO pull PSON# up....Leave a comment:

Re: Lenovo Y540-15IRH internal graphics problem
I would say the schematics shows the only eDP is switchable. I also know for sure that the option is used to be workable on LCD panel until that mentioned incident.
I just remember a desktop technology Lucid Virtu when a customer could use both videocards via one video port. Maybe there is something like that in this model of a laptop, isn't it ?...Leave a comment:

Lenovo Y540-15IRH internal graphics problem
Hi there! I need some help or piece of advice.
A friend of mine kindly asked me to look into his notebook because I have some necessary experience. It's NM-C221 rev 2. A schematics and a boardview I've already downloaded here. Thanks!
Preface: The notebook was in a professional workshop years ago where some job was done, some bios image was flashed and original backup image was lost. So all this time the notebook has been working using discrete graphics with unknown bios image (but someway compatible, because it was updated by a Lenovo utility).
