I am repairing a ASUS AIO V222UA motherboard with i3-8130U. I cannot find the schematic of the board. It has BQ24780S, APW8713E, ATK1604ACGQW, and 4C06B 4C09B MOSFETs. I cannot find a similar schematic and datasheet of ATK1604ACGQW. Google 4C06B and 4C09B also has no datasheet shows only 4C06, 4C06N, 4C09, 4C09N datasheets can be found. The 4C09B Drain has 19V, S and G have no voltage, the nearby D, S, G of 4C06B also has no voltage only resistence to GND. The 19V 24V 12V 5V 3.3V 1.2V 1V 1.8V presents. Any suggestions?
