As the title says, if someone has Boardview or schematics for Dell Inspiron 11 DRAX SKL-Y/KBL-Y MB 15250-1 and wants to share them, I would be very pleased.
I know they are available, just found them on paid websites.
Off topic: Do you know a place where I can find screen datasheets? I'm looking for ld083wu1-spa1 or ld083wu1-spa3.
Thanks.

Re: Asus G751JY dead
Hi again,
sorry for the late reply, but my laptop decided to break so I had to fix it. It is working fine now.
About the board, I removed the HDMI chip U4701 and looks like the short in +3VS is gone.
There is still a short in +3VA_DSWO, which is the output of the 3V regulator PU8100. However, I tried injecting power in both nets, 1V 2A, and looks like the only thing that gets hot is the chipset U2001.
Is there a way of checking whether it is correctly working or not?
In case it is broken, I do not feel confident enough to replace... -

Hi again,
looks like there is something really hot near the HDMI chip (U4701). I am cheking the capacitors. I tried removing the chip but it is still hot.

Re: Asus G751JY dead
Hi,
sorry, it is my fault. What I was measuring in the previous post was the battery output, which, of course, should be off as there is no battery connected. Then, I can suppose the charge chip is ok.
I discovered the problem comes from a 3.3V regulator, more specifically the output of PU8100. There is something shorted in the +3VS net.
I have tried injecting 1V 2A to it and there is something hot around the U3301 chip (ethernet controller?), but the chip itself is not shorted. The heat may come from the other side too.
Can it be a shorted...Last edited by RandomFTW; 09-10-2019, 10:46 AM.Leave a comment:

Re: Asus G751JY dead
Hi again,
I have checked both chips and found the following:
-There is no 3VA EC.
-The charger chip may be faulty, as the regulator is giving 2.5V at the mosfets to the right side (PQ8804 and PQ8805).
-As the charger chip gives 2.5V, the gate voltage of the main battery mosfet (PQ8803) is the same, while the source voltage is 2.5V too. The drain voltage is 19.5V.
Looks like the mosfet is not triggering because the Vgs=0V, but I am not sure about the cause. I suppose the charger chip should give something close to 24.5V so Vgs=5V...Last edited by RandomFTW; 09-09-2019, 10:47 AM.Leave a comment:

Asus G751JY dead
Hi all,
I got a beautiful motherboard disassembled from an Asus G751JY. At the beginning it worked well so, I thought about using it as a desktop assembly.
For this purpose I tried to connect a couple of 3 pin low power fans to the 4 pin fan connectors with some mosfets.
It was working well until it stopped working. After some testing I figured out there was a short in a 3V regulator. I changed the mosfets and now it is gone, but the motherboard still does not work.
I have been testing more voltages and noticed all the regulators are off. Then I checked the SIO power... -
Re: Schematics/Boardview needed for K08PT 0K08PT (Dell Inspiron 11 3179)
Do you have any information about it?
I can't find neither schematics nor boardview for it.

Schematics/Boardview needed for K08PT 0K08PT (Dell Inspiron 11 3179)
Hi guys,
I'm looking for schematics or boardview for Dell Inspiron 11 3179. The board part number is K08PT or 0K08PT.
I tried looking for it in the general ftp server without luck.
If you have another similar model like the 3169 or 3168 it's also ok for me.
Thank you! -
