l've had my Toshiba laptop for about a year and a half now. Last week I got a new charger because it seemed like the old would not fully charge the laptop's battery. But this new charger acts the same way. It will charge the battery a little bit, but it's nowhere near a full charge as I can only run the laptop for about thirty minutes before it dies on me. Is there anyway that I can fix the charger myself or did I get a bad one?
