I've got a habit of using my computer for a few mins, closing the lid, then using it again a couple of hours later..... Then not using it for a couple of days. I rarely turn it off, and dont often take it out of my house. But when im leaving it for a couple of days, im leaving it on, but not plugged in. So when I do go to use it again the battery is empty. Am i going to knacker the battery doing this?
