A.2 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 . Why is it that a CD/DVD cannot be read from or written to? • Make sure that you use a disc compatible with the optical drive. • Check if you insert the disc properly or if there is any scratch on the disc. • Find out if the disc is with write protection.
