Sounds like things are going okay!  I was planning to visit at Fermi with both you and Dana on Wednesday, but that schedule isn't working out so well.  

The description of Mr. Orekoya's student computers sounds like you've found out about the "diplomatic answer" side of the work. Indeed, if a problem is not readily reproducible there is little we can do about it, and a reboot can help in mysterious cases.  :)  The slowness many stations at Fermi experience might be helped by a disk defragmentation or adware-removal; but sometimes seems a mismatch between the hardware and what it's asked to support.

Was that Mrs. Alexander (like, room 222 or so?) who has the going-to-sleep problems?  Checking the power settings, as you mention, is the right approach; but I don't know why it doesn't get right!
