Simple, I plug my laptop's power adapter and doesn't seem to charge. However, when I turn off the laptop and plug the adapter in, then take it out, it give a little charge. Strangely enough, when I have the laptop on with the adapter plugged in, it doesn't seem to do anything. The adapter's light is on, but it doesn't heat up and the battery icon shows the power actually running out.
Should I take it to get looked at? What else could I do?
