Its back cover is still using a single piece of aluminum alloy plate, the YOGA 920 with hidden air inlet and outlet design, the back cover without any cooling holes, there is no hole to solve the antenna problems, it is only has small holes are provided for JBL speakers on both sides of the lower part.
Unscrew 10 screws securing the back cover. You can easily remove the cover. You can see that the layout of the whole interior is simple and clear, and there is no messy cable arrangement. The overall black style has Macbook’s style.
Before continuing to disassemble, we need to disconnect the battery connector from the motherboard.
It may be due to the thinning of the body. The battery capacity is slightly reduced. The battery capacity reaches 70 watt hours in the case of maintaining the 700Wh/L high density cell design.
After the battery is removed, it is also obvious that the YOGA 920 cable is much tidy than the YOGA 910’s.
The speaker is larger than the previous generation, and the sound guide hole is larger. It also makes YOGA 920 speakers sound better.
The touch panel is covered with a thin glass, which can improve the touch feeling. There is also a metal plate on the back to ensure the stability of the point when touching the touchpad.
Take off the touchpad, you can clearly see the two noise reduction microphone cable, can be said to be quite neat.

We split the fan to make a close-up of the fan blade.
Because the fan’s metal blade is very thin, which is conducive to improve the density of fan blades, so as to bring greater air intake and air flow, and then improve heat dissipation efficiency.
Remove the metal shield, you can see 8 memory particles evenly distributed on the motherboard, constitute the memory capacity of 16GB.
The back of the motherboard has two important chips, namely: Realtek ALC3268 sound card chip is very common in laptop, but the Realtek ALC1304 is less common.
After removing all the screws securing the LCD hinge, the LCD screen can be separated from the motherboard.
After you remove the motherboard, you can access the keyboard. It is fixed by a lot of screws.
