I confirm this problem exists in Jaunty, latest kernel (as of July 2,
2009) 2.6.28-13-generic.

My laptop - Toshiba Tecra M4 - with primary battery and media bay 2nd
battery.  Both batteries are detected at first.  After running on
battery for some time, one battery gets drained until total battery life
is ~40-50% remaining.  Then suddenly it jumps to 2% remaining and shuts
down.  Then when I restart, only one battery is detected.  I must
physically remove and re-insert the other battery before it is detected
again.  It seems to be the secondary (media bay) battery that drains
first, and the primary battery is never used, and often becomes
undetected, although I can't be sure this is always the case.

Either way, this is a serious problem for anyone with dual batteries.
It cuts my battery life in half or worse.  I don't know what other
information I can supply to diagnose the issue, but I'm willing to do
what I can.
