Asus K53SD - no power

[cephei328]

Hi guys!

Need help with this

Asus K53SD motherboard - No power

Charger controller tested OK

System power DC/DC - is the problem

3.3 Volts OK but no 5 Volts from the RT8206A chip

RT8206A has 2 EN signals (for 3.3 and 5 Volts resp) When tested 3.3 Volts EN signal on pin 27 is OK but no EN signal at pin 14 (Which is EN for 5 volts). Don't have the Schematics to trace the signal path

Help would be much appreciated!

Thanks

Well, Its a Asus Motherboard K53SJ. For me finding Schematics is hard.

The onliest thing I could find for the K53SJ (=mobo K53SV) up till now is the board view.
Anybody found the schematics already?

Is there a unlocked Bios for this machine? I only can find the Slic2.1.
