Asus k42f schematics needed

[salawayon]

This unit doesn't have an output supply for 3.3v and 5vdc.... I'd checked the RT8206A for the missing voltages but it only gives the ff datas:

Pin
1 - 2vdc
2 - 2vdc
3 - 1.9vdc
4 - 19vdc
6 - 19vdc
7 - 1.9vdc
17 - 1.9vdc
19 - 1.9vdc
24 - 1.9vdc
29 - 2vdc

Thanks....

Replaced the RT8206A with RT8206B and it is now alive. Based on the datasheet of both components they only differ on pin20.. Any info based on pin20 difference?

Thanks....

Ok, I solved it.

Problem was auto on, no display, no fan spin.
FAN Pin 1,2,3 grounded, so I changed ITE chip.

First of all machine wasn't turning on.
I Cleaned ITE chip, now laptop was auto on if power jack is plugged.

Both FAN0_PWM FAN0_TACH were grounded.
