hey guys, ive been experimenting with different ways I could extend the battery life of my new macbook. With the backlight at less than half and the keyboard lit two clicks, I can get close to 4 hours which is more than enough for my needs. I only have safari running, and sometimes aol instant messenger. I turn the automatic light sensor to off cause i think it raises my backlight when it shouldnt, and just having it on might take a bit more juice. Thoughts on that? I have a timecapsule though, so that drains my battery a bit since it does a few backups while im using the macbook around the house. I notice this because the time remaining drops alot while its running. I know its not a scientific measurement, but it goes from 3 hours remaining to something like an hour and change lol. It recovers again once it turns off, but who knows how much more battery life I couldve gotten without those scheduled backups. Im not gonna tinker with that anytime soon though. BUT ANYWAYS, the real reason I started this thread was to ask about flash animations and whether or not they drain battery life? Does a plug in like SafariBlock help in extending battery life since it eliminates those pesky and maybe battery draining flash web advertisements? I just found out about this safariBlock today so please dont hate me If I sound too "newbie" I noticed that during certain web advertisements (the ones that move like commercials), the hardrive turns on or something (since i hear a click underneath the right hand side of my keyboard). I thought that maybe it was the graphics card turning on or something to deal with it. Any Thoughts on that? So i downloaded safariblock and my web browsing experience has so far been very good. Everything seems cleaner and my battery life appears to have been extended. Right now as I type this it says I have 4:27 remaining and ive been using the comp for an hour and 23 minutes. Does anybody else use this safariblock in this forum? does it extend battery life, or am I going crazy? lol Also, an explanation about the clicking sound would be appreciated. Thanks a bunch guys!!
