Re: ASUS TUF FA506IV-AS76 vram mosfet short, then battery cant charge
Just post update and thanks to @mon2 advice, after replacing 2x DCIN mosfet, charge ic finally shut out 17.2v to battery and now charging like a charm.

Yes, I measured the Original mosfet and dimensions close enough to this one.Leave a comment:

lol. MS I have been dealing with a lot as well mostly for game console parts. But for SMD parts, DK has more variantLeave a comment:

Thank you, hunting on DK for DCIN MOSFET now, charging ic I can grab one from a donor.Leave a comment:

My bad, ACDET is 2.65v on BQ24780S PIN6
OMG, you are right, for PQ33, I have low resistance around 2ohm on DS,SG and DG. PQ34 has 18 ohm on GS, DS and DG about 78k ohm.
FYI, I have auto rate UT61E DMMLeave a comment:

YES, I have inspected PQ36,PQ35, PQ71& PQ38. diode reading good.
BAT_PRS# is 0v. LOW . So battery presentRe: ASUS TUF FA506IV-AS76 vram mosfet short, then battery cant charge

I checked HI-side mos and lo-side as well diode reading seems normal, no internal shortLeave a comment:

schematic is similar to FA506IH. Will post BQ24780S pin voltage later on....Last edited by jkyoho; 07-11-2022, 07:27 PM.Leave a comment:

ASUS TUF FA506IV-AS76 vram mosfet short, then battery cant charge
I recently fixed a FA506IV cam with Vram mosfet short on Vin(19v）to ground. Got both mosfet replaced and now laptop could turns on and GPU everything works but battery not charging. Battery status shows 100% on both BIOS page and Windows system.
Measured voltage got 0.3v on battery red lead not going up. charging mosfet gate low and 19v not passing through inductor.
I also tried dc bench supply 14v charge directly onto battery but seems not drawing anthing.
Any idea? -

Re: HP ELITEBOOK 850 G5 ISL9538h area resistor value

reference from DELL laptop isl9538h datasheet. It seems to be low resistance or 0 0hm from my guess.

HP ELITEBOOK 850 G5 ISL9538h area resistor value
Hi all,
wish you have a safe and good day.
I recently recevied this HP 850-G5 laptop with blow/bad isl9538H.
Ordered the new ic replaced it still no standby 3.3v or 5v with only 20v@0.0017A drawing. Digging hard for ISL9538h datasheet and realized the CSIP&CSIN current sense line has 2 resistors value goes off. By any chance anyone know what value of this 2 resistor in the CSIP&CSIN lines are.(RED circle) -
