Question: Why can’t I produce sound?

•

Confirm the sound driver is installed. From the Windows Control Panel, click

System, Device Manger tab, then Sound, video and game controllers. Verify the

Audio Driver is installed. If not, install the driver from the Add New Hardware

applet in the Control Panel.

Question: Why does the communication software not function?

To use some communication software, you have to turn off the power

management. In the Windows Control Panel, double-click the Power icon, and

set Power management to Off. After using the communication software, set Power

management back to Advanced or Standard.

The POST Error Messages

The notebook performs the Power-On Self Test (POST) every time you turn on or

reset the system. The POST is a series of system checks that verifies the correct

operation of your notebook’s hardware.

If the POST detects a critical error (e.g., a system board failure), the notebook will

halt and generate an audible alarm. If a failure is detected in an area other than the

system board (such as the keyboard), a non-critical error message is displayed on the

screen and testing is stopped. You can continue testing when a non-critical error

occurs by pressing the

key.

When the POST encounters an error that requires you to correct something, either a

beep code will sound or a message will be displayed in a box in the middle of the

screen. If you need to enter the Setup Utility to correct a problem, press

Otherwise, press

to continue the boot process and ignore the error.
