i am interested in buying a new ibook. I want to add a big hard drive and blue tooth to it but i'm not sure what effect it will have on my computer battery. what kind of things drain your computer battery? will the bigger hard drive do that?
 
Not ..bigger hard drive wont draw more battery..
Brightness,airport extreme,bluetooth, accessing hard drive, and battery age would affect how much time you get on your battery

infact a smaller ram may cause more swapping with the hard drive and cause faster drain of battery....

cheers
 
if you are going to "add" a different hard drive as an aftermarket modification, then, to save battery power, invest in a faster Hard drive, 5400rpm or 7200rpm if you can afford it. They are generally more effecient in power consumption, and as mentioned before - the less time spent accessing the drive = the more power you save.
 
i havent noticed any drain because of harddrive or BT, but as mentioned, Airport and Brightness and low ram all have an effect so those are the areas of more concern
 
i doubt that bluetooth would use very much, if at all, battery power. apple's smarter than that...
also, a larger harddrive will not cause a change in battery life. the speed is still the same. i think 5400 rpm is the sweet spot as 4200 rpm is slow and i think that 7200 rpm uses a lot of power to spin up... unfortunately, apple only offers 5400 rpm drives on 15 and 17 powerbooks...

depends on the drive you use. and the thing is the 7200rpm drives might take up more juice, its faster, resulting in less power used up
but yeah i agree with you, 5400rpm is slow but nice :)

Honestly I do not see a point to Bluetooth...
 
well..i included active bluetooth as a source of battery drain coz on my cellphone i get significantly less battery time when my bluetooth is active..
so yeah...
