As incredible as it sounds, I soldered the 2 mosfets and started working..... it charges the battery and only turns on with a charger, how is that possible? cold solder?
Thank you very much, fixed!!

with pr8911 in place, I already have the 3v acok =)Leave a comment:

yes, the acok line has voltage with 2.8v decreasing the value....Leave a comment:

Do I put the PR8911 resistor in place before removing the PQ8901 and PQ8904?Leave a comment:

915k resistor off the board.
1.3v still measured at ground without the PR8911 resistor​Leave a comment:

RES 1M OHM is the value it must have, it says on the boardviewer, but measuring on the circuit I have 58kLeave a comment:

so possibly it won't be the ic and load damaged but something next...Leave a comment:

Shouldn't the 3v on the acok come out of the load IC? I have the schematic attached and a photo here

ASUS UX303UB REV2.2 WORKS ONLY BATTERY
Hello
I have an ASUS UX303UB that only turns on with the battery connected, it doesn't turn on only with the charger connected.
With the battery and charger connected, the computer turns on but does not charge and I can see some consumption at the source, it seems to me that the charger is taking over.
In the work environment I can see that the battery is at 24% and does not charge or discharge.
I checked the 24780s load ic and I have the following voltages.

vcc - 18.85
24v acdriver
acok 1.3v

Good morning. I have an hp 14-ce0003np that did not show an image, I repair the ram memory slot and it starts with an image but it takes a long time for the image to appear, when I picked up the hp it had already been repaired by another technician and it may have changed the bios so I don't have the original bios.
Can you help me clear the bios that works, but it takes a long time to show an image?

Re: 15SBGV2D-6050A2548101-MB-A02 short battery
it worked until i turned it on the first time with the replaced mosfets q6012, q6011, q6000 and q6001) on power only. then I went back to being without acdrv. with the battery connected and no current, the laptop turns on and works fineLeave a comment:

Re: 15SBGV2D-6050A2548101-MB-A02 short battery
what I did now:
I changed the 4 mosfets plus the input mosfet too, that is, all, when I connected the charger I got 25v in the ACDRV and it turned on. when I turned it off and tried to turn it back on the ACDRV oscillates between 2v 5v 11v etc etc.... I'm confused as to what it could be......Leave a comment:

Re: 15SBGV2D-6050A2548101-MB-A02 short battery
removing the q6000 I get the same resistance in the battery mosfet.
It's strange, I measured the mosfets and it shows about 65k from source to drain any of them (q6012, q6011, q6000 and q6001), is it really low resistance in the charging circuit?
I'm thinking of changing the 4 mosfets for new ones and waiting for that to resolve, what do you think? and the q6010 changed too?...Leave a comment:

gate (4) & drain (5-6-7-8) - 51k - red gate black drain
6000

gate (4) & drain (5-6-7-8) - 161k - red gate black drain
the ACDRV pin 4 now -1.2v 2.7v oscillating is normal??...Leave a comment:
