HP530 Not Charging

[ft102man]

hello all

I got a hp530 on fleabay recently for a few bucks just for the screen really but the guy sent all the motherboard etc so I reassembled it all tried to power up but it would shut straight down. On further investigation I for PQ 3 to be burn't out of all recognition lucky I had a another faulty mobo. I replaced the ao4407 & to my joy the machine powered up stayed on until I pulled the charger plug out. Does anybody know which other mosfet stop the thing running & charging the battery please or does anybody have a schematic of the power/charging circuits on the mobo.


Thanks
