nah not battery related, its always running off ac power.  the laptop is a toshiba tecra s2, 1.83 centrino, 2 gig ram, nvidia 128meg go6600.  there should be no issues and even in a 23 player server it runs at 80fps.  starting to get very frustrating.  checking the cpu usage again its actually using 30%, alt tabing out releaves the stress it seems.
