Lenovo Y400 game this dismantling
After removing the screw, gently lift it from the edge with the edge of the tool.
The first is to remove 8 screws on the backplane on the D side, which can easily pull up, expose the memory, hard disk, and wireless network card, etc. to facilitate the user upgrade.
After picking up, the back cover can easily pull away from the edge.
There is also a thin layer of aluminum plate on the D cover plate.
There are two memory slots on the back
Whole D side view
Unpacking the D Class cover, it can be found that there are multiple anti-vibration sponges throughout D, which provides protection to the hardware inside the body, and some of the wires are also housed in places that are not easy to encounter, or by insulating tape. Bunch, single from D, the internal layout of Y400 is still more clean.
Decomposition the second part, we will remove memory and hard drives, and cancel the battery. It is worth mentioning that the hard disk is attached, and the thin tin paper is capable of preventing static electricity, the metal frame provides a certain physical protection.

Pick up the keyboard to further disassemble
After that, after confirming that the back of the screw has been removed, it is necessary to smash the keyboard. Similarly, it is slowly "slip" moving along the edge of the keyboard, ensuring that the bayonet of the keyboard has been released. Action must be slow, unavailable, otherwise it may damage the bayonet of the keyboard.
Y400's keyboard keyboard long has a lot from the side view keyboard as a three-layer design
The fan of the C surface also has a metal frame protection fixation
Left interface module
Copper heat dissipation scales are very intensive, effectively increased heat exchange efficiency
Independent power interface module
Among our previous tests, Y400's cooling score under high load is a scratch, which is benefited from re-improved heat dissipation systems. Whether it is a fan of the fan, the double copper heat transfer tube is still a dense heat dissipation scales. Y400. In the game, you can make a better heat exchange, and it is important to note that the metal reticulum in the bottom of the D face is not a low-sounding gun, but the air inlet of the cold air.
Since Lenovo Y400's low version canceled the backlight keyboard, we still saw the interface of the backlight keyboard after being opened, but after the multimeter test, found that this interface did not power, so the hope of DIY backlight keyboard is destroyed.

The second block is independently connected to the host through this interface.
Lenovo Y400's optical drive position supports hot-swapping, we see after we dismantle, there are two inside interfaces, black for the SATA interface, used to connect to the optical drive, white on the left is a new interface, use This interface can be an external discrete graphics card that constitutes a dual card SLI.
The heat dissipation module of the Lenovo Y400 notebook is mainly consisting of a metal heat sink, two copper thermal conductors and a fan. The heat generated by the processor, graphics card, and the South Bridge will be transmitted to the fan by the thermal conduit, eventually discharged from the internal hole of the main unit by the heat dissipation ventilation. This heat dissipation is very reasonable, the structure is not complicated, but the heat dissipation effect is very outstanding.

Some details of Lenovo Y400 work work equally excellent, especially the design of the heat dissipation structure, allows processors, South Bridges, and independent graphics to get good "care", double copper tube and high-density copper heat dissipation in high-load work. It also looks more sincerity.
In the last part, let's take a look at the details of Lenovo Y400 and materials. Not all notebooks use metal rolls. Lenovo Y400 is no exception, the motherboard frame is not all metal materials.

Lenovo Y400 completely dismantled
From the price released on Lenovo official, Y400 is not low. We started suspected that Xiao Y has lost cost performance, but from the results of dismantling, small Y inside, whether it is hardware protection measures or layout line All of them are all excellent. At this point, look at the new generation of small Y at least in quality or trustworthy. As for the price, we still have to wait until the market can finally determine.
