My hp G71 laptop won't turn on, but I can feel the electricity on the metal parts when it's plugged in. When I moved from the US to Ireland I lost my charger, so I bought one over here for my laptop. I think I might've overpowered my laptop and fried it ,but I'm not totally sure. If this is what I've done, what can I do to fix it? Would I be better off getting a new laptop all together? If you can't tell, I'm not brilliant with computers.
