We take out the wires and unscrew the screws holding the cover over the keyboard, the display hinges and the upper part of the laptop case.
When assembling, the main thing is not to confuse where and which screws to tighten. Long, there are only two of them, with a red sealant screwed over the hard drive bay. Short ones, there are also 2 of them, hold the cover over the keyboard, screwed into the holes under the battery. The rest go to all the other holes.

Then we open the connector holding the ribbon from the touch buttons on the panel above the keyboard. The connector (there are many of these in a laptop) can be easily opened with a screwdriver or with bare hands.
Then we easily remove the ribbon cable from the connector. On the cables in this laptop there are "tongues" for which it is convenient to get the cables out of the connectors. Unfortunately, not all "tongues" are well attached to their trains, which is rather strange.

As a conclusion.
From the pros. I liked the assembly of the laptop, in general - everything is decent, good materials, well-fitted. The laptop has 3 mini pci-e connectors and a SIM card reader, it is easy to install a WiFiWiMax adapter, a 3GGPS modem, and there will still be room, for example, for an LTE adapter or mpeg decoder.
The disadvantages include a very thin motherboard, parts of which are easy to bend, and “tabs” on the cables, which are easy to tear off.
But for its price, this laptop is packed pretty well.
