This problem has been reported by lots of people. It appears that for the V6000, in many cases it is a hardware failure. HP has extended the warranty on certain model numbers and will do a free repair. HP has also posted a new BIOS upgrade that changes the way the cooling fan operates in an effort to reduce failures in the future. Some of the component temperatures have been running too high, leading to premature failure of various components, including the wireless, the graphics display hardware, and others.
