I just recently purchased a new laptop, and would like to know some steps to help my battery life span lasts longer. My last laptop battery life span wasn't long and it was only months before it wouldn't last longer than 15 min unplugged. I'm unsure if letting it stay on battery, or leaving it plugged in charging for many hours hurts or helps my total life span of my battery. I would like to hopefully have my battery life span lasts a long time so I don't have to purchase those nice inflated $200 replacement batteries from HP. Any tips are appreciated, thanks.
