Hard drive replaced

Well it came down to it, and I had to replace the laptop's hard drive.  Fortunately full backups were already made, and it just took time to do it all.  A surprisingly large amount of time: I apparently have one of the few laptop brands that doesn't make the hard drive easily accessible, and I damn near had to take the whole thing apart!  Here's the step-by-step video I used to do it.  How tiresome.  Thanks a heap, Dell.
