It`s about N5010.
Usually at the four corners of the video chip i found horizontal and vertical line of silicone.

Inside this laptop i see in the corners 3 balls - one at the corner and one left and right at it. It this the same material?
I should remove them with
BGA IC Epoxy Glue Remover CellPhone chip clean BGA IC adhesive removing liquid
right ?

The motherboard is
x701:14.31818M

Thanks in advance
