Troubleshooting

Why is the sound of my computer's fan so loud?

The computer's fan may be running at a high speed to cool the CPU. By lowering the CPU speed, you also lower the speed and noise level of the computer's fan. You can use the power schemes to lower the CPU speed.

To lower the CPU speed using the power schemes*

1Click Start and then Control Panel.

2Click Performance and Maintenance, and click Power Options. The Power Options Properties window appears.

3Select Portable/Laptop in the Power schemes box.

4Click Apply.

5Click OK.

*Available on selected models only.

Why does the System Properties window display a slower CPU speed than the maximum?

This is normal. Because the computer's CPU utilizes a type of CPU speed controlling technology for power conservation purposes, System Properties may display the CPU's current speed instead of the maximum speed.

Why don't my changes appear on the computer screen (LCD)?

You may need to refresh the computer screen. Press and hold the Windows key, and press D twice.
