A shell membrane wireless signal discount
Film application note: Metal and carbon fiber film will attenuate wireless signals
Most wireless network card antennas in metal laptops are located at the front end of the A shell (at the top of the screen) - PC manufacturers generally use a plastic shell in this section (which is why metal laptops always have a separate plastic shell on the outside of the top of the screen). If a metal film is applied to the entire A surface, the wireless signal is easily shielded, leading to signal attenuation.
Poor heat dissipation of keyboard film and high temperature
Film application note: Do not use keyboard film on notebooks with keyboard air intake
Keyboard film is the most common type of film, which can reduce the probability of liquid splashing into the machine causing malfunctions and also facilitate the prevention of dust accumulation in keyboard gaps. However, not all laptops are suitable for keyboard film.
For these C-side models that undertake heat dissipation tasks, the use of keyboard film undoubtedly cuts off the air exchange channel, thereby affecting the overall heat dissipation effect of the machine. Therefore, if you notice a significant increase in the internal temperature of the laptop after using the keyboard film (you can use detection software such as Master Lu to check the changes before and after), you should consider removing the keyboard film.
Film application note: The gap between the screen and keyboard may be smaller than the thickness of the film
A good screen has left a few indentation marks on the keyboard, which many people will be grateful for. Fortunately, they used keyboard film and screen film, otherwise, the screen would not have left permanent marks. Actually, you're getting it wrong - these indentation marks are caused by the keyboard film and screen film.
