When my laptop is fully recharged with AC power cord plugged in, it says "Computer is running on AC power. Laptop battery fully charged (100.0%). Battery charge time is currently unkown.". I just wonder whether my laptop just runs solely on AC power or it keeps discharging and recharging?

Btw, I got 2.5 hours with ubuntu 9.04, wifi on, brightness nearly max, C2D P8600, 6-cell battery. Was it normal? What is the longest battery life I can get with my spec?
