Suggestions

It is normal for the computer to get hot.

Make sure the air vents are clear.

DOS games and other programs that drive CPU usage toward 100% can contribute.

May be normal Windows behavior (background processing can affect response time).

If the hard disk has spun down to conserve power, it can take several seconds to spin up. You can hear this. You can run BIOS Setup and change the hard disk timeout to match the Suspend time-out.

Certain background operations (such as HP COE virus scans) can affect performance while they’re running.

Some file browsers may be unresponsive while they’re processing a graphic image or waiting for broken network connections to time out.

Run BIOS Setup and try turning off smart CPU mode.
