Power Management Questions..

[eosme]

quick question. i have a 6 cell battery for my x200.

i've just completed a full system update and have upgraded the power management version from 2.35 to 2.5. but i've noticed that on a fully charged battery, after i unplug, the battery meter shows 3:37 hrs left.

is taht normal? also, sometimes it jumps to 4 hrs and sometimes 5 hrs and then back down to 3hr something.

what's going on?
