Battery Lights Dim

So I was ready to play Minecraft when I resized the window (because the default one is kind of small) and since the last Minecraft (MC) update, the window flashed white and red when resizing. I was resizing it when it froze, and the display froze. Well. I took out the charger, slept it, unslept it, and at last it displayed the white screen, then the login-after-sleep window, and I quit Minecraft.

But that isn't the question.

Since that, the battery lights have become dimmer, as in the green lights being duller. Also you know how they usually fade out after a bit? Well, now they just go out without fading, if you know what I mean. Please help! What's wrong!
