Symptoms
Possible causes
What to do
USB devices
(keyboard, mouse)
are not working.
The cables may not be
properly connected.
Check whether the cables are properly
inserted into the ports.
Note that only the USB 3.0 ports (blue
connectors) can be used, and other ports
are unavailable.
You are using a USB hub to
connect to other devices.
There may not be enough power to
supply all of the USB devices that are
connected. Try removing all USB devices
except for the keyboard and the mouse
from the hub, or use a USB hub with a
separate power supply.
The connected devices
(keyboard, mouse) are not
working.
Try using a different keyboard or mouse
that you know is working.
The above measures have
not solved the problem.
Reboot the computer, and try
reconnecting the USB devices.
The computer
freezes up and
becomes inoperable
at high
temperatures, such
as during the
summer.
There may be foreign material
(such as dust) or other
objects blocking the
ventilation ports, reducing the
cooling efficiency and causing
the internal temperature of the
computer to rise.
Remove any foreign material or objects
blocking the ventilation ports.
