I agree.  I'd go further ... don't open and close the lid, don't throw
it around, and don't give it to a child.  (We're talking about a known
defect here that affects a very small number of laptops, )  Give it a nice easy life
sitting on a desk.  Retire to pasture before heading to the knackery.

I agree.  I've found laptops with looser-than-i-would-like hinge and
motherboard screws after children have been using them.  The hinge
screws that are uncovered by disassembly were the most interesting.

No idea ... but a good way to prove the method is to do it to 100
units and then study the results after accelerated life testing on a
shaker platform.  ;-)
