HP Pavilion dv6500

hi i'm a new member here

I have an interesting problem with the HP Pavilion dv6500

the laptop runs on battery OK and starts up
but if the battery is removed the laptop will not start.
all networks like 3.3V or 5V spin cycle, therefore the circuits do not have the necessary power supply it will not start.
However, if I insert the battery with the power off, I will measure both 3.3 and 5V
and the laptop can be started.

I have a schematic but I can't find the point where the necessary 3.3 and 5v are made of 19V

Check pin 1 19v and 10 2.6v of the PU5 chip. You should read 19v on test point 3.
