a shell membrane wireless signal discounts

Foil Note: Metal, carbon fiber film will decay wireless signal

Despite the stunning styling of the new Alienware (alien), the high-end player's quest for personalization is always never-ending. So many people will be again to beautify its shell, such as affixed with metal film! Taobao has new alienware metal and carbon fiber foil, but the use of people are reflected, after the film, WiFi and Bluetooth signal is greatly attenuated. Why is that? The reason for this is simple: most of the metal wireless card antennas, including the new Alienware, are set on the front end of a shell (the top portion of the screen)--PC manufacturers generally use plastic shells in this section (which is why the metal is always "a separate plastic casing" on the outside of the top of the screen The reason). If you attach a metal film to a surface, the wireless signal is easily shielded, causing the signal to decay.

Of course, there are also some notebooks, such as Sony Pro 11, Lenovo Yoga and so on, their antenna is not in the front of a shell, but on the C plane or the bottom of a shell, so even the full metal or carbon fiber as a shell material will not affect the signal.

It was also said that my laptop WiFi antenna is in front of a, with metal/carbon fiber foil, wireless signal is also very good ah. Well, congratulations, you bought a fake! Especially carbon fiber foil, now taobao a lot of fakes, take a plastic film a embossing, known as carbon fiber ...

Keyboard film heat loss temperature high

Sticker Note: Do not use keyboard for the keyboard intake of the laptop film

The keyboard membrane is the most common membrane, it can reduce the liquid splash to the machine to cause failure probability, but also easy to block accumulation of dust in the keyboard gap, but not all notebooks are suitable for the keyboard film. Because a lot of notebooks will be keyboard surface as auxiliary cooling or cold air import. For example, Acer S7, whose memory is thermally transmitted through silicone grease, transmits heat to the cooling copper sheet underneath the keyboard, depending on the flow of airflow to the keyboard. In Lenovo Yoga, the fan corresponding to the location of the keyboard also has hollow design, which shows that some of its cold air is inhaled from the C side to ensure the smooth flow of the duct.

For these C-plane to assume the cooling task of the model, the use of keyboard film is undoubtedly cut off the air exchange channels, which affect the overall cooling effect. Therefore, you use the keyboard membrane, if you find that the internal temperature of the notebook is significantly improved (can be used in the master and other testing software to check the changes before and after), it is necessary to consider removing the keyboard film.

 Screen film keyboard indentation easy to appear

Foil Note: The gap between the screen and the keyboard may be smaller than the thickness of the film

Good screen, Leng left a few keyboard indentation, many people will be grateful, fortunately with the keyboard membrane and screen film, otherwise, the screen is not to leave permanent traces. In fact, you are the reverse-these indentation is caused by the keyboard membrane and screen film. For example, many of the MacBook Air and ThinkPad models have this situation and problems.

Therefore, we should pay special attention to the distance between the keyboard surface and the screen before installing the keyboard membrane and screen film. The method is also very simple, after laying the keyboard membrane, watercolor pen in the keyboard film painting a mark, and then cover the notebook screen, and a little pressure, and then open the notebook, if at this time, the screen has a watercolor mark, then the keyboard membrane has touched the screen. If so, quickly remove the keyboard membrane or replace it with a thinner keyboard film. The screen film is checked in a similar way. If you have to paste both, you have to test it once!

Small series of reminders: Screen film aging problem can not be ignored the proposal does not stick screen film

For screen film, as long as you do not choose particularly inferior products, we will find that when just posted up, the impact on the visual is not large, and different prices of the screen film, it seems that there is not much difference. But in fact, we tend to overlook the problem of membrane aging. If the screen is high brightness, long working hours, a large amount of heat, screen film will quickly aging, and aging performance is discoloration, in the end the clarity of the screen, brightness is insufficient. Therefore, we really do not recommend that you put the film.

Conclusion: The film is useful but not abused, in the notebook profit is getting lower in the big environment, now the merchants are pushing all kinds of foil, it is no wonder that many of the price of the film's profit has been close to or even more than a notebook profits. And many users also out of love machine care or is the pursuit of personalized, keen to buy a variety of foil, but such abuse, but it may be hidden in the notebook. Therefore, the use of foil is really careful.
