Somewhat recently I bought an Acer Aspire One netbook and have been very happy with it so far. However, one of the downsides is the lack of battery power. This blog post shows you a DIY upgrade of your original battery. Creating a battery that is 3 times the weight of the laptop seems to defeat the purpose of a netbook. But, regardless, it looks like a fun upgrade, especially for other old laptops that are dead because you don’t want to spend 50 bucks on a 10 year old computer.
