dv6000 isn't that a relatively new notebook (released jan 2007 or so ) ?
The laptop may still be under warranty, and if not the Hard drive may be under warranty from the HD manufacturer.. Many hard drives carry a 3 year manufacturer warranty.
while doing a quick search on the dv6000 I also found a recall from HP on that series notebook.
you may want to look because if your laptop is affected with wireless connectivity issues they may fix it under the recall for free...
