No audio is heard from the computer.

Check the following:

• The volume may be muted. Look at the volume control (speaker)

icon in the taskbar. If it is crossed-out, click the icon and drag the

slider to the right to increase the volume.

• The volume level may be too low. Check the volume from the

volume control (speaker) icon in the taskbar. You can also use the

volume control hotkeys to adjust the volume.

• If headphones, earphones or external speakers are connected to

the headphone jack on the computer, the internal speakers

automatically turn off.

I want to eject the optical drive tray without turning on the power.

There is a mechanical eject hole on the optical drive. Insert the tip of a

pen or straightened-out paperclip into the hole and push to eject the tray.

The keyboard does not respond.

Try attaching an external keyboard to a USB port on the computer. If it

works, contact your dealer or an authorized service center as the

internal keyboard cable may be loose.

The printer does not work.

• Make sure that the printer is connected to a power outlet and that it

is turned on.

• Make sure that the printer cable is connected securely to a USB port

and the corresponding port on the printer.

I want to restore my computer to its original settings.

This recovery process helps you restore the C: drive with the original

software content that is installed when you purchased your computer.

Note

If your system is the multilingual version, the operating system and language

you choose when you first turn on the system will be the only option for future

recovery operations.
