My Laptop screen stopped working about 1 week ago, but I left it on and let the battery run out and it started working again when I started back up. Now it has stopped working again but the battery trick didn't work. It works on an external monitor, and I can still change the brightness from dark black to lighter black on my screen. Thanks for any help!

I would suspect your graphics cable (from motherboard to display) is going bad. You can attempt to tilt the display at different angles to get a display to happen. If it works at a certain angle, it's most definitely the cable.
Try a reset: with laptop unplugged from adapter and battery removed, press and hold the power button for ~30 seconds, put battery back in, plug in adapter, try to power on then - if you do get a display after reset, let us know, that'll indicate a different problem
