How to fix high pitch buzzing noise from intel based laptops

I recently purchased an HP dv6000 laptop that emitted a high pitch noise.
After some research I figured out that it was actually caused by the cpu going into a low power mode to conserve battery life.
I managed to fix the problem by turning off the abiltity for the cpu to go into a low power state in the bios.
Press f10 at start up.
Use right/left key to access system configuration
Use up/down arrow to select CPU C4 FUNCTION
Disable CPU C4 FUNCTION
Obviously battery life won't be as great but at least the annoying noise will be gone. If you decide later you need to, you can always turn it back on.
Sounds as if the power supply is not up to the job. You won't get a manufacture to admit it though. Hope it works.
