I v got my ASUS X550L laptop 2 months ago. Today I noticed that when the power adapter is plugged, the battery indicator blinks. I tried to turn on the laptop while the power is unplugged. But it didn't started. After I plugged in the power adapter and turned on, it started. But when I checked the battery levels, it said 97% available ( plugged in, not charging). I'm running on windows 8. When I tried to remove the power cable while the laptop is still on, it turned off.
