Frequently asked questions (FAQ)

Power problems

Symptom

I have pressed the

Power button, but my computer cannot start up.

Possible solution

• Check the power cable and power adapter are connected.

- If the indicator does not light up, your computer is not being supplied power from an external power source via the power adapter. Check the connection between your computer, the power adapter, and the nearby outlet.

- If the indicator flashes in blue, your computer has entered

Sleep mode. Move your mouse or click any button on the keyboard to wake the system.

- If the Power button indicator lights up in blue, the computer is being supplied normally with power. Reconnect the power adapter and restart the system.

• Check if the LCD display power indicator stays in blue.

- If the indicator flashes white, your monitor has entered Sleep mode. Press the Power button on the front panel to turn on the screen.

My computer cannot access a modem or a wireless router or access point.

The wireless Internet connection is unstable.

Possible solution

For details about setting up your wireless router or access point, refer to the documentation or user manual of the unit.

For details about setting up your modem, contact your ISP

(Internet service provider) for assistance.

For assistance setting up your modem, contact your ISP.

• Check the wireless interference.

- Reset your wireless router or access point to factory defaults and reconfigure the settings.

For details about setting your wireless router or access point, refer to the documentation or user manual of the unit.

Optical discs problems

Symptom

When a CD or DVD is inserted into the optical disc drive, there is no response.

The inserted disc doesn’t slide out when

I press the Eject button.

I cannot write (burn) a disc (CD or DVD).

Possible solution

• Check the optical disc drive indicator is on.

• Check the inserted disc is not dirty, bent, or damaged. If you

need to clean the disc, see Cleaning the discs.

• Check if the disc is properly inserted into the optical drive, with the label side facing toward you and the disc is centered in the tray.

• Try another CD or DVD (preferably an unused one) to test if the optical disc drive works well.

• If you are inserting a DVD, check the region of the disc. It may not comply with the region set for your optical disc drive.

Check the DVD package to learn if the region code is compatible with your optical disc drive.

• Try using other programs to read the data on your CD or DVD.

• Ensure the computer is on.

• Ensure the optical disc driver indicator is on while you press the Eject button on the optical disc drive.

• Click Start > Computer, right-click the disc drive icon, and then select Eject from the menu to remove the disc.

• Check if the disc is properly inserted into the optical drive, with the label side facing toward you and the disc is centered in the tray.

• Check the inserted disc is not dirty, bent, or damaged. If recording stops during a recording session, the disc probably is damaged. Please remove it and insert a different disc.

• Ensure that the inserted disc is writable, and it must be blank or appendable (with space to add more data files).

• Try writing the disc with other recording programs as some programs cannot write certain disc types.

- If you intend to write data to DVD, make sure that you are recording the data with a DVD burning program.

• Select a slower write speed if you are not under a time constraint.

• Check if the added data files exceed the available space on the inserted writable disc.

• Ensure that there is enough space available on the hard disk drive to store the temporary files that are created during the writing process.

- Click Start > Computer to check the space available on your hard disk drive.

Sound and microphone problems

Symptom

I hear noise when connecting a headphone to the computer.

I do not hear sound from the built-in speakers.

The external microphone does not work.

Certain audio files cannot be played, and the

Codec error messages appear.

Possible solution

• Check if the earphone works well.

- Connect the earphone to other devices, such as a radio, to see if you can still hear that noise. If the noise persists, the earphone may be out of order.

• If you hear the noise only while inserting the earphone to the computer, it is resulted from high instantaneous current. This is a normal phenomenon.

• Check if the speaker volume is set too low or is muted.

- Click the volume icon, , in the system tray to check the

Windows volume controls.

- If you are using a program which has its own volume control, ensure the volume level is properly set.

• Unplug your headphone and external microphone if they have been connected to your computer.

• Check if the external microphone is properly connected into the microphone jack on your computer.

• Check if Windows Media Player is set to automatically download codecs.

- Right-click on the menu bar, select Tools from the opened menu, and then click Options.

On the Player tab, in the Automatic updates area, select

Once a day, and then click Apply and OK to complete the settings.

Then try playing the file again. If the audio file still cannot be played, it might require a codec that is not supported by Windows Media Player.

For more information about available codecs, see the documentation for Windows Media Player at the Microsoft web site.
