On the logic board I can measure 5V and 3.3V only. Can you please let me know where other voltages are generated? What IC to check?
Thank you for help...

Try and update.

I have faulty [B]HP ProBook 450-G2 LA-B181P - [/B]doesnot start. When connecting a charger, the LED on plug in connector blinks from yellow to blue. (I tried to search a short on mainboard.)
What is a common resistance ( to ground ) I should measure on a coil that leads to VGA chip(RT8880CGQW) ? I measure only about 9.6 Ohms. Is it normal?I have faulty [B]HP ProBook 450-G2 LA-B181P - [/B]doesnot start. When connecting a charger, the LED on plug in connector blinks from yellow to blue.
