Check motherboard, close to power socket. I see 2 very small component (1x2mm), flat n thin with 10 tiny spot connect for each. Motherboard writes Q263 Q261 ( or Fs1, Fs 2 maybe), they are too close. They burned both of them.
I don't know exactly what they are, Mosfet, Transistor or Fuse. Because I don't have its board view schematic.
Any help I appreciate!
 
I suggest taking a clear picture and then circling what you are talking about (MS Paint is good for doing this).

Upload the image to a site like imgur.com and then post a link to the image(s) here.

Thank @COLGeek!
I founded what it is. It is dual N- Mosfet with super tiny low profile.
Its code is CSD87501.
Problem is, they are too tiny to solder even find out to know why they burned...hic...
 
Usually, you just replace the motherboard.

The manufacturer could possibly repair because they have the propers tools and knowledge to do so.
