U410/U410 Touch:
The second location - under the fan. Remove the 7 screws on the fan and the
interface, then remove the fan.
After the fan has been removed, apply Cu foil to the red areas in the illustration
below, starting from the blue baseline on the edge of the system board on the left,
and along the horizontal blue baseline of the metal component. (Cover a little
more than the horizontal baseline.)
Note:
1.The yellow area on the left: ensure there’s a good connection between the foil
and the white ribbon cable.
2.The yellow area in the middle: apply the foil directly to the hinge, and ensure
there’s a good connection.
3. The yellow area on the right: ensure the connection is good on the termination
block. If there is a white label in this area, remove it and clean the area before
applying the foil.
