Hello guys
I have this problem with this laptop {won't turn on without the charger}
Now, I have taken the following measurements (batt_on, no AC) :
PQ6 have batt voltage on both sides
Batt connector:
(1+2 have 11.8v / 3= 3.3v / 5= 2.8v / 6= 3.34v / 7= 3.34v / 8+9 gnd)
Pwr_btn has 3.3v
It seems everything ok, but the laptop refuse to start on battery, it starts when I plug the AC adapter
Anyone had this problem before?

What Voltage you get PQ6 S D G all pins ? Only with Battery

Hello techtiger
The PQ6 transistor works perfectly, it switch on when adapter is off and switch off when I plug the adapter
When I unplug the adapter the laptop shut down immediately (snap). I have two batteries one of them is new.
When I had this problem I immediately suspected (either PQ6 is bad or the charging ic not good) but they work fine
The battery charges correctly

Can you confirm +3/5VALWP line B+ line is working fine ? Voltage on PQ4 all pins?
