thanks for answer peste, i tried with your dump but it has de same problem, shows display but keyboard and backlight keyboard does not work, i tried again with my original dump and it does not work either , im thinking that the kbc it8252e248a it is corrupted, can you tell me where to find the dump of the kbc and how to program it with a rt809f programmer, or do i need to replace that it8252e248a?Leave a comment:

Test the theory by shorting PQB11 gate pin to ground, i did this and now acdet is 2.6v...Leave a comment:

Prb36 which is on the line adapdet is 5.8v and pin 1 on pqb11 is 5.8vLeave a comment:

Acer nitro 5 bq24781 no acdrv
Hi people, i have an acer nitro 5 with motherboard model gh51m la-k861p , it came with the resistor pr103 blow up, i repaced that resistor, i check the coils plb2, pl301, pl501 and has no short to ground, i conect the charger and it doesnt power at all, i check pqb3 on pin 5 to 8 and its 19v, pin 1 to 4 its 0
so i repaced, pqb3, pqb4, and makes no change, still no acdrv, i replaced bq24781 and makes no change, still no acdrv, if someone can help pls, thanks, this are the schematic and boardview
