Hello all! New to this community, and a first time laptop owner. Just bought the above mentioned model. Any hints and tips for the new user as to what to keep in mind, how to care for my machine, etc. Also, I have it plugged in now, doing the initial setup. How do I charge the battery? Do I just keep it plugged in until I use it? Bear with me - I'm a big PC girl, but totally new to laptops. TIA!
