Hi guys

I have this laptop that does not turn on after changing charger it did not turn on anymore, make the measurements to the voltage manager and the only measurements that he threw me are the ones that I attach in the photograph
I imagine that they must be some of those resistances but I do not know what value they will be
waiting for your help
Thanks

2. The IC is bq24780S, in the point of entry VCC get 19.2V
Posted after 2 hours 51 minute 35 seconds:
In the mosfet the voltage input M3056M have 19.3V of entry but at the exit its value is 0 volt

bad dog! :D

1. How many resistance between 1 and 2 lamel, and between ground and 1 lamel? (ACN/ACP)
It seems that you have short circuit at AC_BAT_SYS

There is a boardview for this motherboard, free in internet. use it. Check resistance at AC_BAT_SYS first.
