Acer Aspire TimelineX 3820TG - Dead

[JaYmEz]

Model: Acer Aspire TimelineX 3820TG
Motherboard: JM31-CP
Revision: 09921-3

Hello everyone!
This laptop is completly dead, no lights and not charging.
I've already checked the fuses, since there are 5 in this board and all are OK.
So i started to check the DCIN line (see page 49), but when i get to the U1 mosfet, this one is missing from the board and it generates the AD+ voltage.
I double checked the revision and model of the motherboard and it's the same of the diagram.
Voltages from DCIN are only present in this little circurt (the one on top in page 49), the rest of the board doesn't have voltages.
Here is the diagram:

If anyone can guide thru this.
Thank you.

Hello,
Do you fix this notebook? I have same problem as you. Ntb is completely dead, no lights, nothing. I have also same motherboard as you and same revision, but I have U1 mosfet soldered near input voltage connector. AD+ and AD+_TO_SYS voltages are ok, power button is ok. I'll look on it better tomorrow.
