I have an Acer Aspire 5335 Notebook, It's had the black screen problem for a couple of days. It starts up, flashes the Acer logo screen for a split second, then goes black. I've tried tapping F8 when it starts up, but it just beeps. When I shine a light at the screen, I can very faintly see the screen. I haven't tried hooking it up to an external monitor yet because it doesn't have an HDMI port and I'm not sure how else to do it. I've tried removing the battery, holding the power button for a minute, then starting it up, all that. The problem seems to be outside of my computer knowledge. Can anyone help?
