I have a Dell Inspiron N4010. Every time I leave my computer for a little the screen would turn black and I thought at first it was just sleeping but it wasn't. I notice that my power button is still on, but blinking. i tried to move my mouse, click with my mouse, smash buttons, and closed my lid and opened it again, but it all didn't work. the only way it would turn back on is if I press the power off button and reboot, which is extremely annoying. I saw there was a thread/post by Dell talking about the black screen and how I needed to update my drivers with the new BIOS. I did that, but when it was downloading it said I already have the newest version so nothing changed. Why is this happening and how do I fix it?
