Geek Tip: Dial Down Display Brightness For More Juice

Since I like to plan ahead, I knew that I needed to fully juice my laptop battery the night before WWDC in order to be maxed out for the two-hour live-blogging event the next day. But unfortunately, unlike the new Macbooks that were announced at the Apple keynote, mine does not last for seven hours. I'm lucky to get two and a half! But I'll cut this bad boy a break, cause it works really, really hard. So to preserve power, I shut off all unnecessary programs, and turned down the brightness on my screen to squeeze out every bit of power I could (there were no outlets in the audience). This not only helped get me a few extra minutes blogging time, but it helped to keep the annoyance factor down a notch for the other geeks in the crowd. I mean, keeping your laptop at full brightness during a keynote would be like checking your iPhone for messages during a movie. Bad form, indeed.

for those of us running PC laptops, pulling out the DVD/CD drive saves a lot of battery. Also, turn off bluetooth and any other radio's you are not using at the time.

I have a Macbook too [the current version/generation], and I remember when it first came out, Apple claimed that THIS one would have 7 hours of battery life! But I agree with all your tips - I cut down my screen brightness, don't run videos or music or any games while it's off the A/C adapter unless I'm just around my house and it's nearby - I also set the battery energy saver preferences...most of the time I can get 3-5 hours of life, usually around 3.5 hours regularly. I don't turn my computer off much, either, though - it's so long to reconnect to the internet. I bet I can get more life by turning it off more!
