 i was running a suspend/resume test from os56.  autowack-delay was set to
 d# 1000, and linux was doing:

 {{{
 while sleep 1
 do
 echo mem > /sys/power/state
 done
 }}}

 some time (hours?) after this was started, the battery went into error
 mode -- red-light flashing.  cause is "FF count", which implies eeprom
 corruption.  the outlet into which the laptop was plugged didn't have a
 solid connection, so i'm not sure whether it was powered or not.  watch-
 battery reports 67% charge.
