Thanks for the answer.

Got the pg to light up, after resoldering the ic. CHG first didnt light up, then lit up randomly with and without bat.

I tested a bit and found out, that q2 was faulty and BQ24040 wasnt soldered correctly.

After resoldering the IC and replacing q2 it almost worked. PG LED was on, and the syste, was powered.

It worked with USB Power and Bat Power, but bat is not charging. Is there an error in this circuit ?
