Re: a full re-index of the hard drive on the next boot
I think Apple engineers are bright enough to include reason codes in their event logs. Re-indexing due to a simple low battery condition would be dumber than a box of frogs. All laptops safely shut down when power is critically low to avoid borking the lithium cells. Well, dunno about Apple but Windows will force an emergency hibernation state when power < 2%, so when the tester fires it back up, no disk errors should have occurred.
This just sounds like poor battery management.
