I hate that laptop batteries have memories. I hate that it takes forever to recalibrate them. I hate that I did this to myself.
I kept the laptop on all the time. When I didn't need it, I'd just close it, put it to sleep. I kept it plugged in all the time, so as not to "waste" charging cycles. Dumb. Every morning, I'd unplug it long enough to read my email and news while I ate my breakfast, and plug it back in before I left for work. Half an hour or so.
And so I trained my computer to believe that the battery only holds half an hour of charge. And now it doesn't even hold that. I'm going to try to recalibrate again, but... yeesh.
Wish me luck.
