Hi,
I got myself hands on a Asus ViviBook X512F which the seller said has been liquid damaged that has no power. The motherboard number is 'X512FF' - Rev 2.2. I am using a genuine ASUS 45W Power Adapter. When plugging in power adapter there is no lights that illuminate and the machine does not power on when pressing the power button.
When I removed the motherboard from the chassis it seemed one of the components was completely burnt out! I have attached a picture below of the component which i have successfully removed, circled in white, this is the component that was burnt out on my motherboard. The connector to the left of this is the LCD connector. The issue i have is the component being so badly damaged i have no idea what SMD it is or its values. I have searched for the schematics and board view, yet to no avail.
Was wondering if anyone who has one of these machines/knowledge of/or can shine some light on this can help me out on this ideally if possible to identify the component incl. values so i can seek a replacement.
When doing a cursory inspection of the board there does not seem to be any voltage going to any of the main inductors on the board and from what i can see the power is reaching up to the second mosfet @ the initial buck converter at the power supply. The voltage then stops at that mosfet drain and does not appear on the source side of mosfet. I am thinking at the moment in time this is a consequence of the protection that’s built into the board and once i have replaced the burnt component this will then kick the board back into gear.
Any help would be appreciated.
P.S Also the image above is not a picture of my board, this is, for illustrative purposes only to show better the burnt out component.
