Hi I really hope any of you can help. Here's the deal: I was using my laptop normally and suddenly it turned off. I was watching a video and right in the middle of it the laptop stopped working. I tried to turn it on again and it wouldn't. I tried changing the battery (my boyfriend has the same laptop), using another power cord, and changing outlets. One thing I did notice is that the AC light doesn't turn on when I connect it to the outlet. It doesn't work with any of the cords. What can you say?? I have an HP Pavilion dv6458se.
