BTW, I have info for people having specific problems with their Concerto.
  I've been through just about every problem (the only original part on 
  mine is the motherboard, and some have been replaced twice or more), and 
  while a pain to get ahold of (like 20+ mins wait) the Compaq tech support 
  has been extremely good about getting things fixed.  For anyone with the 
  problem where the plastic breaks around the handle hinge next to the 
  battery: they have a new design with an improved hinge mechanism, 
  although it may not be available for a few months yet.  Contact tech 
  support and get yourself onto the list if your plastic is broken.
  
  This problem is caused by the looseness of the hinge.  If the side of the 
  handle can pull away and be pushed back towards the case, the metal tab 
  (which can be seen by removing the battery) can slip past the lower 
  (towards screen) plastic catches, and then it only pushes on the thin 
  outer plastic when the handle is moved.  Eventually this will cause the 
  plastic to break.  If you notice that your hinge is loose enough to allow 
  this to happen, I recommend pushing the metal tab thingy back into place 
  and using superglue (be careful not to spill any) to hold it in place.  
  This should prevent it from breaking in the future.
