Hello guys.
I got an broken x55a Asus laptop. I found that these x55 laptops are not stable and die all the time. I searched high and low and found even 4 threads here on badcaps about these mobos. But unlikely no thread helped me locate my culprit. So as everyone else problem with this laptop is that when you power it on the mobo starts and after some time cpu fan starts working too (probably when heated more than room temperature) but the display stays off. Same happens with external display (via vga port). So I opened it and everything seems okay. I measured some voltages and its all 19,5,or 3V (somewhere 1.V). The thing I noticed too is that 4 caps near cpu are all short circued same as that grey block element (marked red) but the bottom cap isn't shorted. Can you at least point me out on what should I check to find the culprit? Also how can I test those 3 mosfets in the same circuit?
Here are the pictures.
