my laptop charger doesn't work. I've only had my laptop for 3 months, and now it won't charge, i don't know if i need a new laptop charger or if it's the DC jack. For a couple of days, when i plugged my charger in i needed to move it around so it would work, but not much. and now it won't work at all. so i am wondering if it's maybe the charger itself or the DC jack. what do i do?
