Asus X512UF doesn't switch on

[Luca Arsiero]

Hi all,

the card shows no signs of life..
even disconnecting the battery there are no signs of life.

Unfortunately I don't have the schematics but I tried to measure the voltages and stopped at the first MOS (mobo.jpg)
On the drain there are 19V but on the source and gate there are 3.1V.

I noticed that near the MOS a component could be damaged.. but I'm not sure and I can't read anymore.. (mos_1.jpg)

Someone could give me some suggestions?
Thank's a lot

Hi. We cannot read the mosfet markings at all from this side. Each click shrinks the pic. Post larger and clear pics if possible. Apply some alcohol onto the top side of the blown mosfet and see if that helps to clarify the markings. Also post a larger view of the logic board. There may be other similar logic boards from Asus which we can study for the missing details.

Hi mom2!

Thank's for your suggestion...I hope these images are better...

I've tried to clean with the blown components...but without improvements...
