With the UBook X, the SSD is not integrated on the mainboard, but rather inserted into an M2 slot. It is an M.2 2280 • M.2 / B-M-Key (SATA 6Gb / s) - SSD. Chuwi usually uses a Morebeck-S100 256 GB SSD. Well, it’s an inexpensive entry level SDD.
If you bought the Ubook X on Amazon / Ebay, you should complain about it there. If you have imported it yourself, the complaint is an adventure. Then you should consider exploring the problem yourself.
If the SSD is not found in the BIOS and the Sata ports are all activated, there are several options.
- SSD no longer has proper contact due to the transport in the M.2 slot
- The SSD is defective
- The M.2 slot is defective (but unlikely)
You can open the UBook X quite easily. Unscrew the two screws on the back (under the stand bracket), remove any microSD card and pull out all USB and power plugs. Then use your fingernail, opening tool or credit card to enter the gap between the display and the frame and widen it carefully. So then go around the whole display.
It works similarly to the Hi13 video. Only that the screws are on the back and no cable is attached to the lid. So they can’t accidentally tear off anything.

Then the back cover is off and you come to the SSD. This is fastened with a screw. Loosen screw, take out SSD. If you have another device to test, you should test the SSD there. Otherwise, insert the SSD again correctly and screw it tight.
It looks like this inside.
The image is here from the forum and from the UBook Pro. The Ubook X looks basically the same, only that the SSD is rotated by 90 degrees and is directly in the M.2 slot on the mainboard.
If the SSD is not found after this, it is probably defective. You could then buy a new SSD (e.g. the Samsung SSD 860 EVO 250GB, M.2, Samsung SSD 860 EVO 500GB, M.2). Basically all M.2 SATA SSDs run with M.2 / B-M-Key in format 2280.
Here in the forum I have already seen the original Win10 recovery image. This allows you to reinstall the original Win10 installation.
Personally, I immediately took an original Win10 version from Microsoft. However, it will not be easy with the drivers. I had to search a long time to get all of the drivers together. But it can be done. My fresh Win10 installation now has all the drivers together.
But as I said, this is only a viable option if you are ready to “tinker”. If you have the opportunity to complain, you should first take this option.
