The persistent battery issue - post 10.2.8 update

[Jennifer Landefeld]

Hi All,

The only things I'm noticing after my upgrade is a battery that has 
gone from 3.2 hours to 1.4 hours at a 99% charge. Well, that and an 
increasingly flaky Safari.
I too fix permissions, keep back-ups, etc. before upgrading but that 
didn't prevent the battery issue this time (never appeared before for 
me).

Before I reset my NVRAM or Power Manger, what will be "wiped" out with 
either of those actions? I've been searching the knowledgebase and 
online various places and all I see is the process, not what I'll clear 
ultimately. Is it more than just clock, power management settings? Are 
there other things I should note before resetting so I can put things 
back as needed after returning to a default state?

Sorry if it's a dumb question.

Thanks,
Jenn
