I've not been a user of laptops much until just recently. I do have a re-furbished HP laptop. One thing that I'm curious to know is if it's typical for the battery to die if the laptop is not in use and not plugged in for a few days. When I put it in its satchel, when I bring it out to use it, I always have to plug it in because the battery has completely drained. Does it need a new battery or is this typical?
