How do I build in my M.2 SSD module?  

In some cases, the M.2 SSD module may not fit into the slot. The solution to this is simple and complex at the same time.

A compatible M.2 SSD module has a B&M key, which means there are 6 pins on one side (B key) and 5 pins on the other side (M key). First, identify the position of the bar in the mounting base. Often the B key with the 6 pins is on the left side while the M key with the 5 pins is located on the right side – but in some cases the opposite can occur.

B&M key picture example

Attention: Please note that under certain circumstances, the expansion slot in the device can only be recognized by an oblique view in the housing due to its design.

Now try to insert the M.2 SSD module with the B key located on the left side. But be careful: Apply only light pressure here. If the connection does not work then you should not increase the pressure, as this could damage the module or the socket.

If the connection between the module and the slot does not work, this is often a sign that you should turn the M.2 SSD module (= B key with the 6 pins now on the right, M key with 5 pins on the left). Try again to connect the module to the slot.

Sometimes it may be necessary to insert the SSD not slightly obliquely into the socket, but first lay it flat in the mounting slot, then align it horizontally and gently push it towards the socket until the SSD slides into the socket.

Take a closer look to see if the SSD is in and not above or below the socket. When properly inserted, the semicircular notch on the other end of the SSD curses with the bushing for the mounting screw.

Please note: M.2 SSD modules from TREKSTOR are always compatible with TREKSTOR hardware. M.2 SSD modules from other manufacturers should also be compatible in most cases. If the insertion of such an SSD module does not work during the first try, this does not necessarily mean that there is an error here.

Why does my screen turn black after my password entry?  

In rare cases, the screen may turn black after entering the Windows password. Only the mouse cursor ist visible. The issue can be quickly bypassed by pressing CTRL+ALT+DEL key and restarting the device at this point.

It should now appear a notification of the system that Windows update is being performed. Thereafter, the PRIMEBOOK U13B works again exactly as it should and the error is permanently fixed.

How can I switch out of S mode?  

Caution! : Turning off the S mode is a one-time process. If you make the switch, you will
not be able to return to S mode from Windows 10 Home.

a) Open the Microsoft Store.

b) Enter "Switch out of S Mode" in the search bar.

c) A window will appear "Switch out s mode".

d) Click on "More information".

e) Click on "Install".

f) If necessary, log in with your Microsoft account.

g) Confirm that you have saved all your files.

Advice: If you have not saved your files, they can be lost.

h) Windows 10 Home will now run without S mode.
