Product Overview

Slim companion for at home or on the go
The Surfbook E11B is the ideal notebook for anyone looking for a compact and lightweight device that can reliably handle day-to-day computer work. The device offers all the important communication and mobility featurest to maneuver through the day. The efficient Intel® Celeron® N4000 processor, combined with 4 GB of RAM, provides a dependable work environment that provides sufficient resources and energy for the office day.

Windows 10 Home in S mode
For the extra boost in speed and user comfort on the Surfbook E11B there is Windows 10 Home in S mode already pre-installed. The operating system is characterized by an excellent power management and a consistently high performance. Add that to the highly increased security, as only security-certified Apps can be installed from the Micrososft Store. And if you prefer to switch to the normal Windows 10 Home you can do it directly and with no additional cost.

Natural pictures and a pleasant operation
Wether office applications, streaming services or apps: The matt and glare-free 11.6 inch Full HD IPS screen displays every detail in natural colors with razor-sharp details and rich contrast that allows the content to really shine from every angle. By the way: The keyboard is optimally enclosed in the housing and, thanks to the well coordinated key stroke, ensures a completely pleasant operating feeling and is therefore particularly suitable for real frequent users.

Fanless design
The Surfbook E11B has a so-called passive cooling system that does not need any fans. On the one hand, this results in almost silent operation and very good heat dissipation as well as a longer lifetime of the device since there are no ventilation slots for dust deposits.

Office 365 Personal
Ideally equipped right from the start: The Surfbook E11B offers the full spectrum of Micrososft Office 365 Personal immediatly after unpacking. Wether it is Word, Excel, PowerPoint or Outlook – with that software package you do not have to forego any productive advantages. And thanks to the helpful cloud features, all files are stored across devices, making them easy to open and edit from basically everywhere.

SSD memory extension on request
You can never have enough memory space. And if it ist the fast paced SSD memory, then certainly not. Fortunately, the Surfbook E11B has a smart extension slot that can be fed anytime with a 42 mm SSD module to increase the precious storage capacity even later.


* Office 365 Personal for 12 months included, software is already pre-installed. Office activation is required within 6 months of Windows activation date. After expiration, the license must be renewed for a fee.

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 SURFBOOK E11B 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.

How can I perform Windows updates on my SURFBOOK E11B?  

With enabled internet connection your SURFBOOK E11B checks the availability of new updates daily and displays a message in the Info Center when new updates are available. To keep your device always up to date, it is extremly important to regularly connect the device to the internet. If you've select "Express Settings" in the startup wizard, the first time you've switched it on, the SURFBOOK E11B automatically executes available updates at shutdown (download and installation). You can change this setting. To do this, enter the settings and choose "Update and Security" -> "Windows Update" -> "Advanced Options" and select the desired installation method for updates.


Why is my SURFBOOK E11B charging slowly?  

If you have connected the SURFBOOK E11B for charging and set your device at high exposure at the same time (eg movie playback at 100 % display brightness while surfing, chatting or playing), the battery is charging very slow due to the stress. We recommend you therefore to load the device in the off state.

Why is no sound coming from my SURFBOOK E11B?  

You may have headphones connected to your SURFBOOK E11B. If headphones are connected the loudspeaker of the device is automatically turned off. Disconnect the headphones from the device to re-enable the speakers. If there is still no sound, check if the sound of the device is turned on and if the volume is set high enough.

Why can't I turn on my SURFBOOK E11B?  

Perhaps the charge of the battery isn't enough to turn the SURFBOOK E11B on. Connect the charger to the device to recharge the batttery.
