compaq cq61 DA00P6MB6D0 REV D power problem

[sourcebf]

Hi for all,

can anyone help me to solve this problem, i have a hp compaq cq61 with mobo DA00P6MB6D0 REV D which does not want to work
I followed the diagram the 19volt stops at the level of the N-channel mosfet PQ48 (see the attached photo) in addition to that I took a reading of the voltages of the charger IC (see the attached photo)

noted that I have changed PQ48 as well as the charging circuit without any result ???

You need the Gate pass for PQ48 , the Voltage on the Gate should be +28V trace it back

Check PU4 pin 8 if you don’t have 28V change it but this IC is very difficult to find
