Speaker Problems

Check the following problems to see the possible cause and solution.

No sound from the speakers.

Check that the system power is on.

Check that the system AC power adapter and AC power cord are connected to the power
source and the back of the system unit.

If an optional headset was used, check that it is unplugged.

Sound is only coming from one speaker.

Balance the speaker output by adjusting the balance in the sound software (see the
Microsoft Windows Multimedia online help).

Speaker volume is too low.

Adjust the volume control on the front of the system. If the volume is still too low, adjust
the volume through system software (see the Microsoft Windows Multimedia online help).

Diagnostics

One beep indicates that the system has completed its POST test. If intermittent beeping occurs,
power off the system and try again. If the beeping persists, see the following table. The table
summarizes problems that might develop during system operation and lists (in sequential order)
suggested corrective actions.
