Troubleshooting
Read the following Q&As for troubleshooting guide. If these do
not give you answers, you may contact us directly at the contact
information provided in the support DVD.
What can I do if my Desktop PC cannot be powered on?
Check if the power LED on the front panel lights up. It does not
light up if no power is supplied to the system.
• Find out if the power cord is plugged in.
• When you use an extension cord or a voltage regulator,
ensure that you have plugged it into the wall socket and
switched it on.
What can I do if my Desktop PC cannot enter the operating
system?
• Make sure that you use memory modules that the system
supports and that you install them properly on the sockets.
• Check if your peripheral devices are compatible with the
system. Some USB storage devices, for example, are with
different disk drive structure and enter sleep mode easily.
If the above steps do not solve the problem, contact your retailer
or perform system recovery using the supplied recovery DVD.
You will lose all your data during the system recovery. Make
sure that you make a backup of it before recovering the system.
Why is it that I cannot hear anything from my speakers/
headphones?
Check the volume icon on the Windows® taskbar to see if it is set
to mute . If so, double-click this icon to display the volume bar,
and then click the mute icon under the bar to cancel the muted
mode .
