From my understanding, most DV6000s had a major hardware issue where the motherboard failed, whether or not that may still happen to your system, you might want to look into a newer system instead of dumping money into that one for that reason. However, what is the exact model of your laptop? Knowing that will give me a better answer. (it should be somewhere on the bottom, if it's not on the top, something like dv6292 etc.)
