Why does my SurfBook just switch off sometimes?
If the energy level of the battery falls below a critical level,
the SurfBook displays a corresponding warning.
If you ignore these warnings, the SurfBook is put into sleep
mode at a charge level of 5 per cent in order to counteract total
discharge of the battery. Total discharge can lead to a situation
where it is no longer possible to charge the SurfBook. For this
reason, connect the tablet to the charger at this point at the
latest in order to prevent data loss and damage to the battery.
My SurfBook won't switch on. What can I do?
The battery may not be sufficiently charged to allow the
SurfBook to switch on. Connect the SurfBook to the charger (see
Section 7) to recharge the battery.
Which e-book formats are compatible with my SurfBook?
You first need to download an app from the Windows Store
(see Section 16) to be able to read e-books on your SurfBook.
You can search specifically for free apps to display e-books. The
functions of the selected app will determine which e-book
formats you can read on your SurfBook.
How can I install Windows Updates on my SurfBook?
Your SurfBook checks for new updates daily (an Internet
connection must be available) and displays an appropriate
message in the Action Center when new updates are available. To
ensure your SurfBook is always up-to-date, it is therefore extremely
important to connect the SurfBook regularly to the Internet (see
Section 14). If you selected the "e " option in the start
xpress settings
assistant when you switched on for the first time, the SurfBook
automatically performs available updates when you shutdown
(download and installation). You can change this setting at a later
point in time. To do this, call up the settings (see Section 13) and
select the method used to install updates under "u & "
