Acer One Z1402

[dspok]

Hi everybody,

I have a motherboard of said model which wasn't turning on. No sign of charging, totally no power. Found gate controller of Q29 wasn't working, changed Q53. Now mobo power ups, and battery charging.

But now problem is it can't power up on battery without adaptor inserted. When it is turned on and I unplug adaptor it works on battery.

Anybody please be kind enough to help me to short out the problematic component.

Schematic can be found here...
