I remember when I was young, using old school laptop computers like the 8088 based Toshiba T1000 (damn, the good old day, and I even ran LucusArt adventure games on it) , I always had to carry my AC/DC adapter with me. Now I am using Lenovo X60T, which is supposed to be more power friendly. Well, sad things happened when I just a while realized that my machine was in low battery. Only 25% of the battery life left, and I have 2 hours to kill.

Well, guess what, after using it for almost an hour, I still have an hour of juice back, which is not too bad. Technology sure goes a long way.
