The computer is off (or in Sleep Mode) but
powered by the AC/DC adapter plugged in
to a working outlet, or by battery with a
capacity above 20%. I have plugged a
device into the powered USB port in
order to charge it, but the device is not
charging.
The port is not powered on. Toggle power to the port using the Fn + power
button combination.
This function may not work with certain external USB compliant devices (check
your device’s documentation). If this is the case, power the computer on and
connect the external USB device in order to charge it.
Note that this function is designed to help charge USB compliant devices, but
is not designed to allow their operation.
The system will not start up
when being
operated
in a low temperature environment
.
The lowest operational temperature tolerance of the system is listed at 5°C. In
addition to being operational at this temperature or above, if the system is to be
run in DC mode (on battery) in low-temperature conditions, the battery must
have a remaining charge capacity of 80%+.

The Sound Blaster audio controls don’t
work when the system is connected to an
external display through an HDMI/
Display Port cable.
Note that Sound Blaster Audio will be disabled when you are connecting to an
external display through an HDMI or Display Port connection. See “Sound
Blaster Audio & HDMI/Display Port” on page C - 7.
