I replaced it with a BQ24780S and the conditions remain exactly the same. How could I increase the AC voltage? It's currently 2.49. Could I remove or change the value of any resistors?
...

the resistance between ACN (Pin1) and the sensing resistor (PR8200) is 0.6 as is ACP (Pin2) with (PR8200) is 0.6...

Work for me...

UPDATE!

After checking a few times and trying different BIOS, I managed to get video output again with the IGPU, but it still doesn't detect the GPU.
I have the schematic for LA-l651p and boardview of similar cards LA-L761P or LA-651p that help me identify some connections, but I'm a bit stuck on this topic.
I'm sure I measured 0.78V on NVVDD
0.95V on Pex_VDD

As you can see in the images, the GPU driver is not detected in the BIOS, Device Manager, Driver, or NVFlash

Touching the 2 probes, this is the reading I got on the lowest measurement my multimeter has.

This is the reading by touching ACN(Pin 1) ACP (pin 2)

...

yep, between ACP(pin1) & ACN(pin2) = 0.9ohm
resistance for ACN(Red) to GND(Black) =15.45k...

ACDRV (pin4) its on = 0.010V
Resistence between pin APC and ACD is 0.9 ohm...

I am guided by the following schematic diagram

These are the mosfets on the input line

I have an HP 16 DAG3MMB3AAO REV A. The charge LED doesn't turn on.
So far, I've checked the three input MOSFETs, and all three seem to be in perfect condition. The charge IC is a BQ24781. The voltages I've checked are:
VCC: 19V
REGN: 6V
ACDET: 2.45
ACOK: 2.85

It's striking that I don't have voltages on the ACP, ACN, and CMSRC.
I'm a bit stuck on how this controller works and why it won't turn on.​

Check U6 seems to have the same configuration...

It doesn't appear in the device manager, in BIOS or in Dell tests. I also tried with nvflash, mats and mods and driver without success.

As far as checking all the coils are powered, but I can't check them completely, because I don't know how to turn on the motherboard outside the case, I don't know if it detects something specifically connected to turn it on completely, since if I only connect the power button, it turns on for a second and turns off.

I checked the first voltages as best I could in a few seconds, and they were all there. The only one I couldn't find in...

Hello, I have a Dell Alienware M15 R7 INTEL LA-L651P which does not detect the dGPU which is a 3060M, I tried reprogramming both BIOS, without success, the dGPU has all the voltages, I do not know how to make it turn on properly with an external power supply, since outside the case, it only turns on for a second and turns off.
I tested in vBios and on pin 2 of the eeprom I have no voltage, on pin 1 I do have 1.8V
I also disabled the hybrid GPU in the BIOS settings and the Windows startup sound is heard but there is no image, with a color code of 2 red and 7 blue on the power LED. It...
