10 Ways to Extend Laptop Battery Life

lifehack.org: "When you travel with your laptop, you would want long battery life. It’s extremely important when you travel on the plane, where you have all the time to be productive, but the battery couldn’t last as long as your concentration - ouch. "

they need to invent a wireless battery wall adapter thing.

my computer battery has died, I need a new one, so for the time being I just plug my computer in, but I always have the problem of finding an outlet that is close to where I am.

it be great if there was something I could plug into my computer and something I could plug into the wall and my computer would never run out of power

I love that the article proposes to talk about the work you can get done on a laptop on the plane if only the darn battery didn't die - and yet the article starts with the reality of attempting to watch a movie on the plane with a dying battery. So what do we all do on our way home for the holidays? Take your laptop and some movies - and a good book.

flying home takes about 14 hrs for me. it is the most boring moments of my life. i learned most of these things few days ago. If i read this article earlier, my life would have been much more appreciating. however, i will use these informations on the way to go home for winter break!

Most of the suggestions are common sense to computer savvy people. There are so many things that aren't mentioned though. The biggest one in my mind being disabling the search for wifi in an airplane.

There are some goog ideas here, and I agree "be gentle" sounds a bit suspect; however, I take plane rides as one of the few times I disassociate myslef from my laptop. I generally feel quite liberated to turn off my phone and computer for a few days.

The biggest difference for me in battery life is remembering to turn off the wireless internet, it makes my battery last 3x longer if the switch is off. And i don't mean just trying not to run internet-based programs (IE, AIM, etc) but actually using my finger and flipping the switch. In addition, turning off the volume is great. But a lot can be said for having a spare battery that you don't usually keep in your computer. Because lots of laptops are left plugged in (mine has become more of a desktop than a notebook) battery lifespan just diminishes over time. Having a "travel battery" that is capable of holding its charge longer because it's not left plugged in is a great way to solve this problem. -- Maddie Regan

So the idea of a wireless battery charger sounds great, except that I really don't want anymore electro magnetic waves passing through me than I really need. The problem with this is that in order to have a "wireless" generator that runs off of a changing EM field, you need a really big EM field with a really high frequency. All of these things could reek havoc on all of your other electronics, including the computer itself.

Another good hint is to buy a Mac laptop. My powerbook has great battery life and easily makes it through a movie on a plane. I can typically get through a movie and a half on my plane rides home, before having to stop. But its not the battery that stops me, its the end of the trip. When I turn off the airport and bluetooth, dim the screen, turn off the backlit keys, and set the processor to conserve energy, I can go about 5 or 6 hours doing typical work before needing to plug in.

ugh.this article reminds me of how my computer just have poor battery life. this is the type of thing where if you know that you're going to be travelling, get a computer that's light and has a lot of battery life.
keep in mind your lifestyle you make a major purchase like a computer.

As some mentioned above, the methods in the article are common sence. Then the better way left is "only run what you need". And "only use it when you really need".
Nowadays, We really rely on the computer in everyday life. Maybe we should bring a spare battery when we go out.
BTW, I found my iBook's battery seems more durable than my HP Centrino Duo.

another good one is to keep it well ventilated.
With my laptop, if i keep the bottom about an inch off the surface of a table (not in my lap or wraped up in a blanked) the fan almost never has to turn on.
If the processor can run cool enough by itself, it will not use the processor fan and save battery life.
