Hey guys looking for the Bios for an Asus ROG G713PV-DS94
Motherboard Number is g713p-mb-VGT 6050A3468901-MB-A01
Serial Number is R3NRKD03613412E

i am not sure if any additonal information is needed if so let me know and i can update this post. Things i have tried are to download the BIOS directly from Asus but that file is a .329 file and is 32MB as opposed to the 16MB file i need. Scoured high and low and cant find this darn BIOS anywhere! Much appreciated!!...

I have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.

When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...

I am still new to this, so I might sound brainless/ignorant in parts of my description/questions, since I have a lot of gaps in my knowledge, but I will do my best.

The laptop is Lenovo Legion Y540-15IRH, and the motherboard model is NM-C221 Rev 2.0 (Schematics and BoardView can be easily found). To save time I have the exact problem in the laptop as the one shown in this video:
[url]https://www.youtube.com/watch?v=tfucZ_WKpz4[/url]

I was checking the voltages I found that the main power rail V20B+ is good, and same for the +3VALW circut, but when I tried the +5VALW,...

Good morning.
I need help. My old mac book air model A1466 EMC 2632 serial C02M6TLEF5V7 is password locked on the firmware. I tried to make some attempts with the ch341a programmer but, not being an expert, I can't solve it. The programmer tells me that the chip is a 25 spi flash winbond w25q64fv. I didn't understand how to remove psw. I worked on the disassembled board. How do I know if it's ok?
Thanks for your help. I managed to save a copy of the bin file but the post won't let me load it with a bin extension.

Can I ask you guys help me identify this godforsaken component?

i got it with a "popped cap" while there are many damaged components on it, which got succesfully identified with one exception:

While wall mounting, I mistakenly picked a screw 0.5cm too big than the clearance and damaged the trace and one of the part (a capacitor, I think) on the board. Images attached.

Is this repairable or will I just have to get the entire board replaced? Please guide about this.[U]Hardware Details - Samsung LC24FG70FQWXXL (C24FG70) Monitor with the board model (BN91-18169A) perhaps aka (BN41-02548A)[/U]

Dear collegues,
the owner of this machine brought it to me saying that suddenly one day the display didn't turn on anymore, he tought that all the machine was damaged but it turned out that the MacOS starts good and stays on, and that connecting it to an external display it works without problems.
If you take a look into general settings, you can also see that the internal retina display is recognized as connected by the main board but for an unknown reason it doesn't turn it on.

Attached schematic 🙂.

Laptop gives no signs of life. No fan and no CPU heat.

Think Engine BD4179MWV is hot on plugging in *AND* pressing the power button.

Discovered short to ground on VCC5M power delivery IC NB690GRP (5 volt line, not the high current VCC5M_PD) which is one of the ways that chip is powered. I'm puzzled.

Nothing else is warm on the board. CPU resistances are OK, 9V VSYS line is present from the BMIC. All misc and cables are disconnected.

What do you guys think happened? I've got two theories:

Hi,

working on a ASUS ROG STRIX GL702VSK 60NB0DZ0-MB1260 that does not power on. At the PQ8900 PIN2 (P_CHG_ACMOS_G_20) I am receiving 24.7V and PIN1 (P_CHG_ACMOS_S_20) 20V, however when I place the PQ8901 P_CHG_ACMOS_G_20 it drops 0V. I don't have the replacement mosfets ( N-MOSFET QM3058M6AC PRPAK5*6

I have a 12v psu from a DJ lighting system and I can not seem to figure this one out. The board so far had a blown fuse and a shorted voltage regulator. After replacing those I get 12v out but hooking a load to it the voltage seems to bounce between 5v and 0v. I remove all the caps and checked those and replaced 2 that were only questionable. I know it's not the device I connect it to as I put 12v to it with my bench power source and it works fine....

Hi everyone, I have the same problem with two Dell notebooks. One has the EDC41 LA-G891P motherboard and the other has the EDC50 LA-901P motherboard. Both do not turn on and the processor also heats up a little.
In the coils there are 3.3v - 5.1v - 13v - 19v - 1.8 - 1.05V and 1.0V prime core
On both notebooks, if I press the power button the LED turns red and if I release the button the LED turns off.
What could I still check before saying the processor is dead?
Thank you

This has happened on three keyboards, so now I am assuming it is something in the machine but I can't track it down. Every time you plug in a logitech wireless keyboard it will immediately switch the "c" and the "v" permanent on these boards. There is no malicious software I can find, the board cannot be reset or put back. The very last one I tried was a MK 235 with the same end result. If you plug in a Microsoft wired comfort curve board, no problem at all. I have tried cleaning the system, deleting all boards from the device manager, updating the Logi software,checking MS...

I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.

Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.

Any idea what the problem is?
