I've had my laptop for 3+ years, it's an Asus f556u, and the other day infound that the charging cord was broken almost completely through and was sparking. So, I unplugged it and bought a new cord but the battery still wouldn't charge. I bought a new battery and replaced it. when I turned on the laptop and plugged it in it looked like the laptop recognized that it was plugged in but it still won't charge at all and now the charge that the new battery had is gone and the laptop won't turn on at all. Any ideas?
