Go to the post bar and ask the Digital House. You can't ask here.

There should be a ** disassembly tutorial in that.

1. Turn over the notebook, pick off the battery, and loosen the screws, you don't have to screw them completely, as long as you feel that they have been unscrewed from the screw holes.

2. Use a crowbar to pry open the D shell from the position where the circle is located, clockwise, along the seam. After prying it around, it may not be able to be completely taken off at this time, at this time, only the slag should be held with the D shell and gently hinged the screen.

Send it in the direction and you can easily take off the D shell.

3. Large heat sink.

Below is the CPU, which is soldered to the motherboard, so the CPU can no longer be upgraded; The red box is the memory slot, which has two slots; Inside the white box is the wireless network card.

Inside the pink box is the card reader.

location; The blue box shows the SanDisk U110 16G NGFF 2242 SSD; The yellow box is an HDD.

location; The green box is where the built-in battery is located.

4. This is sandisk u110, ngff2242, if you consider upgrading, you can replace it.

5. Built-in battery, unscrew the screws, pull out the connecting wire in the rectangular frame, and you can remove the built-in electric pool of the shirt.

6. Unscrew the screws in the circle in the picture, lift the hard disk support up slightly, and pull it to the left.

Just remove it, install the hard disk, and do it in reverse order. Dismantling is complete.

Notes:

Be sure to disconnect the battery in the BIOS.

It is difficult to dismantle to mean that the workmanship is good!

What do you need to dismantle? Not specific enough.

I wouldn't be at first, but then I tried it carefully and opened it without much effort.

First, loosen the 8 screws in the back, and use your fingernails to open the small buckles along the gaps little by little (I use the nails), or use special slices. It's just that it's a little difficult behind the battery, so get the perimeter open, lift the back cover, and push a little hard in the direction of the battery.

It's all unclear. I'm going to change it today, and I want to see how thick it is. The back cover is very good, just two screws.

There is also a screw on the hard disk, and after you put it down, you can take it out by lifting the screw position of the hard disk a little bit and moving it back a little. The aluminum foil is glued to the hard drive, and it is a bit troublesome to scrape it with a razor blade. If there are 4 small columns on the plastic frame and the small holes on the side of the hard disk stuck together, you should break them out carefully.

This design is much stronger than Dell's R15, and Dell's clean fan requires nearly 30 screws. Hard drives are millimeters.

You only need to unscrew the eight screws at the bottom to pry open the bottom case along the gap.

See below for details**, there is a comprehensive tutorial, you can ask if you don't understand.
