Re: Dell Inspiron 5748 - Intel Graphics wont work
OK so I just tried to install the Intel drivers while connected via team-viewer, and it seems that the actual driver is installing properly, but the screen goes black as soon as its installed. I can use the computer via team-viewer, so I went to check the displays, and it seems that the Intel graphics driver isn't able to detect the laptops internal monitor, is there anyway to get it to detect it?Leave a comment:

Dell Inspiron 5748 - Intel Graphics wont work
Hi there
Hope someone can help me with this problem I`m having on my sisters laptop.
Dell Inspiron 5748, win 10 or win 8.1 (Have both on separate disks for testing),
Intel i7-4510U, Nvidia GT-840m
If I have the Intel graphics enabled all I get is a black screen and if i try plugging it into a monitor it doesn't pick it up. If i have the Intel graphics disabled everything works fine except its permanently running on the GT-840m so battery life is bad. I thought it was a windows 10 problem because it came about after an update, but that was a long time...Last edited by MARHD; 01-30-2019, 09:23 AM. -
Re: Acer 5760G - Quanta ZRJ dead, no power
Ok so I'm going to replace it, but I'm not sure of the value for the resistor. The datasheet says 2.2_6 what value is that exactly? Is 6 the number of zeros?...Last edited by MARHD; 01-23-2019, 04:03 PM.Leave a comment:

AHA I shorted the resistor and the laptop turns on! is it safe to just remove it, or should I replace it?Leave a comment:

I can remove it, or short it?...Leave a comment:

Re: Acer 5760G - Quanta ZRJ dead, no power
So remove L26 and C579? and then check the resistor again? Or remove all of these caps also?...Last edited by MARHD; 01-23-2019, 02:08 PM.Leave a comment:

Re: Acer 5760G - Quanta ZRJ dead, no power

Re: Acer 5760G - Quanta ZRJ dead, no power
R418 has 3.3v on the U22 side, and 2.5v on the other side.
I checked the Bios pin 8 on the C586 capacitor, and it was 3.3v, the other side of the cap was low voltage. you can see on the pic...Leave a comment:

Re: Motherboard schematics archive?

Re: Acer 5760G - Quanta ZRJ dead, no power
PL14 has stable 3.3v on both sides.
Pin 95 of u22 has 1v.
Pin 102 of u22 has 2.5v
Pin 19 of u22 has 2.5v
But pin 93 of u22 has 3.3vLeave a comment:

Re: Acer 5760G - Quanta ZRJ dead, no power
Ok for the one switch that was 3v it is now also 1v, not sure why. Also the led above the power switch has 3v, which is odd since it is so closeLeave a comment:

Re: Acer 5760G - Quanta ZRJ dead, no power
Just to make sure, which are the two mosfets i can check for 19v on?Leave a comment:

Re: Acer 5760G - Quanta ZRJ dead, no power
The u21 is missing 5v, I'm not sure which is pin 2 but i checked all the pins and very low voltage on all pins, below 1v...Leave a comment:

I can't find them, and I don't have the boardview to do so...Leave a comment:

I forgot to mention that the power button has 1-1.2v instead of 3vLeave a comment:

Acer 5760G - Quanta ZRJ dead, no power
Hi guys,
I'm trying to fix the laptop above. I have 19v I'm pretty sure, and I have 3v at certain places but not on the power button. This is super weird since I have 3v on one of the other buttons near it, the IC's near the power button are also missing 3v but some have 1.8 and 1.5v. The weirdest thing is that when i short two pins on the ic in thr picture the fan starts spinning but nothing else, when i dont short it, the fan has no voltage at its connector.
Please help, also does anyone have the boardview for this quanta ZRJ, I cant find it anywhere.... -
Re: Dell XPS L322x dead charging circuit
Ok cool. I can`t seem to find the AO3409 locally but I did find the DMP3160L-7 as a cross reference. Do you think it will work? It seems pretty close (I have attached the datasheets)...Leave a comment:
