Product was DOA. I FINALLY got it working by exchanging power cords a couple times and literally jiggling things around for a couple days. After I finally got it running it sounded like a jet plane starting up. After contacting the vendor they told me to check inside the case for something loose. I found the shroud that goes around the fan and or processor was just laying inside the case, not connected to anything. I fixed that and it quieted the fan noise down. The hard drive, from day one, makes a noise that to my best description sounds like the gurgling at the end of a coffee pot cycle. The vendor said regarding ALL the above that they could help me with "warranty" claims. The thing was DOA and had other issues, there should be REPLACEMENT, not WARRANTY claims. Further research led me to find out the vendor was in Canada, so shipping it back to them, AT MY COST for a DOA product, was not in my best interest. Also had issues with the Windows authorization, and to this day I can't let it go to sleep, or I have to do a hard reboot using the power button at least 2-3 times to get it to restart, getting HP OS error messages in between each restart. I have given up on it, it is beyond hope and a total waste of my time and money.
