When you plug in your laptop, you usually find yourself greeted with a cheerful chirp from your PC, a new glowing LED indicator light, and a display that perks up and beams a bit more brightly.
At least that's what it's supposed to do. Sometimes, though, you connect the AC adapter—usually because the battery is nearly drained—and you get nothing. No glowing lights. No brightened display. And no battery charging. What went wrong? Why won't it work, and what is to be done about it?
It may seem simple enough to recharge a laptop. You plug it in, it works; easy, right? Well, not necessarily. Between the wall outlet and your battery are several steps and parts that can all fail.
