I have a compaq v2030us. It is small, compact, VERY bright, and fast... only thing is even with the screen on lowest brightness the battery meter shows 89% and 2.5 hours... compaq says that it gets at most 3 hours but i cant understand why other, even bigger notebooks (like gateways) get 5+ hours... i would buy an extended battery but they are enormous! are they any generic extended batteries that will NOT harm my computer
