The good news is that she admits to setting the laptop down "abruptly". Since there are no recordings of the incident, I'll take her word for it. My professional opinion is that she damaged her internal hitachi system drive (buried the heads or what have you). Now the system won't boot, and the laptop does not see the hard drive.
It's been a while since I had to deal with this. I moved the SATA drive to my workstation, and my BIOS sees this drive. Booting, I'm now waiting for windows to decide what to do with it. Years ago, someone told me that if the mechanics of a drive were stuck, you might get away with smacking it on the desk once or twice to see if you could free it up. Anyone else recall something like this?
Thanks
