Hi All,

I got another interesting question from a reader named Matt on the Laptop Experts website that I wanted to run by all of you and get some opinions.  Matt and his wife were debating whether or not unplugging and plugging back in a notebook's charger to let it run on battery power a couple of times a day would maximize the battery's performance on the laptop.  My answer was that he should let the batter completely run down before re-charging, but I wanted to ask you all if you had any tips or tricks on maximizing battery performance?  And while we're at it, have any of you ever heard any myths about notebooks battery life that made you do a double-take?

There are all kinds of "tips and tricks" out there that may or may not work. I would say it's fine to leave it plugged in as long as you drain it every now and then.

here is my $0.02 in the deal. it really does not matter because laptop batteries are only good for max of 2-3 years.

I still got my Dell E1505 is about 3 years old and i have not replaced the battery. and it is always plug in. unless i'm in the sofa or in bed. even with my XPS 1530 which i use it for work purposes is always plug so it does not matter. btw laptop are only good for 4-5 years after that you have to start swapping cpu fan and others things....

I do pretty much the same thing as Bob, and haven't had bad results.  My laptops are plugged in most of the time, but when I do have a chance to use it on battery I typically let it drain all the way (and I've not noticed much depreciation in battery life doing things this way).

What part of "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn" don't you understand?

I don't have any lappys, but I have been doing that with my first gen Ipod nano. It stays plugged in in my car, but every now and then I bring it over someones house or something. It's little battery is still running strong.

 I am eagerly anticipating Hyperspace, which I read about in WIRED. It lets you run applications without having to boot up your OS or run your OS. I have not used this myself, but I am interested in trying it to see if it really does make a big difference. I looked up the link to the WIRED article. Here it is if you want to check it out.
