 Replying to [ticket:924 andrey]:

 > 1. the laptops all ran for a while (about 4 hours), at first their
 batteries were charging (orange light) and eventually they were fully
 charged (no light)
 >

 Thats problem one.  Fully charged is Green Light.  No light usually mean
 Battery absent.

 >
 > Eventually all five units 'died' like this and we haven't been able to
 get one to boot all the way back up since.  However the amount that each
 will boot seems to have something to do with how long the battery is
 removed for.

 It sounds like you batteries just failed to charge and they are below the
 level where the Laptop will operate.

 Please unplug the AC adapter and your battery and wait 10 or 15 seconds
 then plug up _only_ the AC adapter.  Then try to boot the laptop.  It
 should boot.

 Once its booted you can insert the battery and see if it will charge it.

 Also if you can get the laptop booted then we can upgrade you firmware
 which may help and also there is some additional diagnostic info in B73
 that we can run.
