The illustration below shows how it looks after the area on the upper cover
which is under the fan has been treated;
Note: In the green box area, apply the foil to the upper cover to enhance the
adhesion.
Confirm the following tasks have been completed. Connect battery interface,
then follow the disassembling and assembling instructions and assemble the fan
and bottom cover.
1. Having applied absorbers to the bottom cover as required.
2. Having applied Cu foils to the adapter interface and the area under the fan as
required.
3. Having replaced the wireless network card as required.
Note:
1. Connect antenna to the wireless network card correctly: port M should be
connected to the black antenna, and port A should be connected to the white
antenna.
2. The assembling process requires gentle handling to avoid bottom cover
deformation.
3. Copper debris may be caused when applying Cu foils. Check and remove all
the copper debris from the system board, to avoid short circuit.
If the network card has been replaced, when you’ve finished the assembling, log
into the operating system and remove the old wireless network card driver and
bluetooth driver from the Control Panel manually. Then reinstall the wireless
network card and bluetooth driver.
Note: The old bluetooth driver has to be removed manually before installing a
new one. Otherwise, the bluetooth driver may not function.
When the steps above have been completed, follow the normal procedures to test
the machine.
