Information
The back-up battery will not be recognised by the device if it is connected
while the KeTop is running.
The status symbol in the taskbar of the display can indicate the following
statuses for the back-up battery:
Status symbol
Condition
Battery completely charged / being charged
Battery almost completely charged / being
charged
Battery more than half discharged / being
charged
Critical battery status (no further back-up possi-
ble) / being charged
Very critical battery status (no further back-up
possible) / being charged
Battery was removed during operation (this
symbol appears only if the back-up battery had
not previously been initialised).
The KeTop switches to the back-up mode if the external power supply is
disconnected. In back-up mode, the display is switched off and the touch-
screen, the keyboard and the USB interface are deactivated. The CPU and
the file system (
Flash and RAM
) remain active. When the KeTop is con-
nected to the external power supply again, it switches back to the normal
operating mode within 1 second.
