low power actions?

[pgf at laptop.org]

a thread on irc from last evening prompts me to ask:  where can i
find a description of how the laptop behaves (LED behavior, powerdown
behavior, etc) as the battery gets low?

brief searching led me to 
  http://wiki.laptop.org/go/Power_Management#Power_Management_Scenarios
but this scenario (battery getting low/critical) doesn't seem to be
covered.
