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 fine

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......

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?...

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

source (1-2-3) & gate (4) - 28.9k- red source black gate
gate (4) & drain (5-6-7-8) - 161k - red gate black drain
the ACDRV pin 4 now -1.2v 2.7v oscillating is normal??...

Measure the resistance to ground of the drain pins (5-6-7-8) - 3.1k
I changed the mosfets for new ones and still the same problem remains.
curious that the notebook turns on with the battery inserted, but if it has a battery and a charger, it shows a short circuit in the source....Last edited by ivangserrano; 02-22-2023, 03:10 PM.

Hello
without resistor 6018.
ACDRV pin 4 - 22.30v 23v oscillating
REGN pin 16 - 6v
I tested it after a few minutes and now I have pin4 with 7.5v and pin16 with 6v...Last edited by ivangserrano; 02-22-2023, 07:48 AM.

15SBGV2D-6050A2548101-MB-A02 short battery
hello
my laptop hp 15SBGV2D-6050A2548101-MB-A02 does not turn on right now.
If you make a direct connection from the first mosfet source to drain, it turns on, but if you put the battery in, a short circuit appears in the source.
Turns on and works perfectly just connected to the battery and connected to the charger but both (battery and charger appears short circuit in the source and the first mosfet heats up and starts to smoke. (this without the first mosfet)
If you put the first mosfet, the gate oscillates between 5v and 15v,...

Toshiba L50-A
Good afternoon, I have a toshiba l50-a that doesn't consume anything at 0.000 amperage.
I checked the Q8800 and Q8801 input mosfets and I don't have the 24v.
I removed them and measured and they are good, even so I put other compatible mosfets, the computer starts connecting the image but if you turn it off it goes back to the same.. I lose the 24v on the gate. Could the problem be with the ic charger (U8800A)?
I change the Q8800 and Q8801 again and it works until it turns off.
can you help me please...Last edited by ivangserrano; 08-03-2022, 07:35 AM.
