HP G62 dead, but board has power everywhere..BIOS?

[Blacktek]

DA0AX2MB6E1.. this laptop has its 3v and 5v power rails in good conditions, im getting 3.3v on 5 out of 6 pins in power board connector.
bios: 3.3v on pins 3,7,8 and 1.5v pins 2,6.
What voltages should i check for?

Voltages on system power IC RT8206B
1=2v
3=5v
4=14v
6=19.5v
7,9,10=5v
12=1.2v
14,15,16=5v
17=10v
19,20=5v
24=8.5v
25,26=3.3v
27=5v
30=3.3v
31=1.2v
32=5v

Does this look correct?

update: when i unplug A/C adapter and attach the battery, the charger ic doesnt show sign of life, no voltages anywhere.
Also, PU2 RT8207AGQW, im getting weird voltages when A/C is plugged in and no battery. Pin 6=5v, Pin 12=18.5v, pin 22=4.6v.

start it and check all SUS voltages

well on battery , normal values are 3.3 volts feeded by KBC power source , if youre having voltage around 4 volts not normal at all , what kind OF DC adapater are you using ? does machines are sensitive with not regulat dc charger
