Time remaining on battery does not include both batteries

2010-10-11, 1:06 AM

I have a T400s running windows 7 with the latest BIOS, Power driver, and Power Manager software.


Each time I unplug the time remaining estimate is accurate for about 5 minutes, and then it drops significantly. As my battery drained, I noticed the remaining time reflected my secondary ultrabay battery only, and not both combined as it had previously.


I have tried to remove my ultrabay battery and reinsert it, but I always get the same behavior. Does anyone know how to configure the display?
