How to fix my motherboard?

crwdns2934249:0crwdne2934249:0:

Hi

Please help me repair the motherboard of my Dell Inspiron E1505 laptop. The laptop doesn't start when I push the power button.

Here it is what I tried so far:

- start it without battery in, only using power adapter

- start it without any RAM

- start it using a known good power adapter

- CMOS reset

But my laptop is dead. No beep, no LEDs, nothing.

The power adapter is putting out 19.8V.

I have the service manual, I have even the schematics of entire laptop. I opened it looking for any obvious signs of damage on the motherboard. But no luck. I checked if DC power socket is firm in place. It is.

I am quite proficient at electronics, but not too familiar with laptop repair. Perhaps somebody can tell me where to start measuring the basic voltages (3.3V, 5V, etc). I can take photos of motherboard if that will help identify strategic points for measurements.

Thank you.
