SOURCE: high pitch noise
For laptop repairs & parts, pls try here. Not really that hard a fix but major concern is how soon do you get the parts and how to confirm your diagnosis.
You may want to consider other possibilities such as:
1. mechanical problem (fan motor bearing, CD/DVD spindle, HD platter; and/or
2. CCFLamp inverter.
Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.

My lap is also dv6000 and i have no symptoms like that.
it seems some thing is going wrong inside. As your lap is under warranty you should contact your service centre, it will be free.

High pitch noise usually means the inverter board that drives the lamp behind the LCD display. If the rest of the laptop appears to work, for example, hard drive light blinking while booting, try hooking up an external monitor and hit whatever function key that switches you to the external monitor. If everything works, you may want to replace the inverter board yourself. It is not horribly hard if you are very careful. But it is not exactly a walk in the park kind of work.
If the rest of the laptop does not appear to work, the DC-DC step down power circuit is probably shot, which will also make a high pitch noise. In this case, you will have to replace the motherboard. Replacing a motherboard is a major pain in the behind. In most case, it is not worth the trouble if you have an older model.
