The issue is that after removing a dead battery pack, can the above notebook work with only power adapter?
There is no schematic available so I use the LA-G07DP for the regulator SY8286B.
At the 3V regulator the needed +3VPCU is 0,2V with 4,4V at the enable pin 11 [EN2].
When I have the battery connected I get the 3,3V at +3VPCU.
For the battery circuit I use schematic DAG35AMB8E0
The battery normally gives the +BAT_RTC and the second way is the +3VPCU through a diode [PD1010].
There is no short but when removing the diode I have the +3VPCU voltage.
With the diode if there is a battery providing the +BAT_RTC the +3VPCU works too but with no battery the +3VPCU drops low cause it somehow draws too much current trough the PD1010.
The resistance after the diode is 1,4Kohm.
What am I missing?
