I have this computer that when the motherboard is turned off and the battery connected the battery discharges.
I've already checked the Q60002, Q60003, C6000 mosfes and they're not them. How can we detect where this leak is coming from?

On page 16 i not have PM_SLP_S5#_R when i press start with AC adapter but if i just conect the battery and press de start buton i have 3v PM_SLP_S5#_R.
If i reset the bios and conect the ac adapter the notebook start well automatic ( normal) but if i press the power... -

Battery not Charge NM-B421
Hello i have this circuit and my battery not charge.
I was changed PU101, PQ103,PQ101,PQ102, the battery and the problem is the same.
When the bactery is conected:
PQ103:
pin1: 19v
pin4: 19v
pin5: 11v
when the bactery is not conected:
PQ103:
pin1: 19v
pin4: 8v
pin5: 19v
Why works the opposite? EC Problem and need programing?... -
