acer aspire 4572G power problem

[salawayon]

Infos: core i5 processor with nvidia vchip.
= JE40HR

With this unit, at battery only it works ok even charging is normal. Without battery and using only a charger it won't power up (sw voltage 3.3v, PL4101 = 0V, PL4102 = 0V,)... Reflashed bios same status, replaced rt8223m twice same result...

Any info how to solve this problem?...

Reflaced charging ic same result... BTW, it will only charge the battery when the unit is already powered up...
