#924: B2 shuts off after a while, battery no longer charges

Component:  hardware  |    Keywords:  battery b2

 We have observed the following problem with five new B2 units, which were
 unpacked from the box and then plugged in.

 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)

 2. one by one, each laptop shut off completely without user intervention

 3. when powering on a 'dead' laptop, the green light briefly comes on and
 then the whole thing powers off again

 4. if I take the battery out and wait several minutes, replace the
 battery, and press the power button the laptop will power on and get
 either as far as the firmware screen or (at best) a few steps into Linux
 boot, but will then power off again

 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.
