I tried loading recover disks on it and got the PXE-E61 error. something about no OS and something about a cabling problem.
As it turns out, it didn't recognize the hard drive because it wasn't long enough-meaning that when whoever put the hardrive in, the caddy didn't place the hard drive far enough back into the slot to make connection. There is an inherent difference between the 15" and 14" in models. I don't know if they use the same caddy and an adapter or if they have a different caddy the places it back farther into the slot. I removed the plastic lid and slit it back into the drive slot and now the operating system is loading just fine.
I know you all probably know this, but thought I should share since I saw others with the same error.
