Solution
It's possible that a voltage spike, power outage, or brownout has occurred.
Symptoms of voltage spikes include a flickering video display, unexpected computer
startups, and the computer not responding to your commands. A voltage spike can
occasionally corrupt or destroy files, so it is a good idea to consistently make
backup copies of your data files. Prevent voltage spikes by installing a surge
suppressor made for use with computers between the power outlet and the computer
power cord.
Press the Mute button on the keyboard to see if the Mute feature is turned on.
Use the keyboard controls to increase the volume.
Click the Volume icon on the taskbar. Increase the volume, and make sure the
Mute box is not checked.
If your speakers have a power button, check whether it is turned on and whether the
power supply is connected to the power source.
Check the speaker connections.
Remove the headphone connection.
Check the button configuration. To configure the button:
1 Click Start on the taskbar.
