(1) No OS installed - machine started with a bios No OS found, fixed by recovering a image of a similar machine (which was what I was planning to do)(2) laptop power supply had issues - would power the machine on but would alwaya reset just before bringing up windows gui.  Either faulty or the 65 watt wasnt enough to fully power the machine (online specs reference 90watt). Used my lenovo laptop charger as a temp replacement until i could get a replacement (Amazon gave a small credit towards buying a replacement power adaptee)Would of been 5 stars if the machine had worked out of the box
