Connecting peripheral devices
Troubleshooting sound
My speakers are not producing sound
❑ If you use external speakers, check that the speakers are properly connected and the volume is turned up. If the speakers have a mute
button, make sure it is off. If batteries power the speakers, check that the batteries are inserted properly and that they are charged.
❑ If you have connected an audio cable to the headphone connector, disconnect the cable.
Connecting a Universal Serial Bus (USB) device
You can connect a USB device (for example, a mouse, floppy disk drive, keyboard, printer) to your computer.
USB devices are plug-and-play devices. You do not need to shut down your computer prior to connecting these devices unless the
manual supplied with the device states otherwise.
For some USB devices you need to install the software before you connect the device. Not following this procedure might cause the
device not to work properly. For more information, check the manual provided with the USB device.
When you are playing a DVD (video or audio) and you want to remove a USB device, such as USB-compatible speakers, make sure
you stop the DVD first. Removing a USB-compatible device during DVD (video or audio) playback may cause a malfunction.
To prevent your computer and/or USB devices from damage, observe the following:
❑ When moving your computer with USB devices connected, avoid any shock or force to the USB connectors.
❑ Do not put your computer into a bag or carrying case when it has USB devices connected.
❑ Connecting a USB mouse
❑ Connecting a USB floppy disk drive
❑ Connecting a printer using the USB connector
