I am looking for as many tips as possible for conserving battery power.

I have a 15.2" 1.25Ghz Al Pb.

I am going to Turkey in 7 weeks and the longest leg of my flight is 10.5 hours.

Obviously, I will be getting a second battery and I know that even the 2 batteries won't last the entire time, I will try to get some sleep.

However, I am looking for tips on how to conserve power.

I run Codetek Virtual Desktop and Konfabulator and noticed my time remaining on the charge increased by about 30 mins when I shut them off.

I want to be able to watch movies and videos to help pass the time.

Does watching movies (DVD) from the drive eatup that much more power??

Yes, unfortunately, running any CDs or DVDs will drain your battery very quickly.

Other things you can do to try to conserve battery power is:

-Turn off Airport
-Turn off Bluetooth
-Turn down screen brightness
-Set your computer to Longest Battery Life in Energy Saver (This might not work so well for DVDs. There is a DVD playback setting in energy saver as well, but I don't think that setting is necessarily to save battery life)
-Take out CDs and DVDs when not using them

= mute sound when you do not need speakers

= use headphones instead of built-in speakers

= disconnect all peripheral devices

Create a Network Location with all of the network devices disabled and name it something like "low power". I've got one and it really helps when I need every last second of juice in my battery.

don't know if ruins your portability, but since you mentioned buying an extra battery, this sprung to mind. An external battery mentioned on Yourmaclife:

supposedly gives 10 hours additional battery life, so you have two to spare.

I was on a 23 hour flight, with the longest leg lasting about 12 hours. The best thing I did was get the Kensington Car/Air Adapter. It's $79 and well worth it. You can get it cheaper if you search online at other sites.

No matter how good the battery is, it will not lasts you 10 hours. Trust me, get the Kensington Adapter and worry no more.
