I just got a surface pro 3 from a family member, they said they found it without a charger. So, I bought a charger on Amazon assuming it would charge the tablet. I was wrong. There is no indicator light, no sign that the tablet is charging at all. I haven't had it work the whole time I've owned it, I don't know if the tablet is shot, or if the cable doesn't work, or if there is a method of fixing it I haven't tried yet. Anybody have any ideas? Can I disassemble it? Or is it a paperweight now?
