I fell asleep last night with my Acer on, I noticed it needed and update. When I woke up I realized I had left it on and so I turned it off, when I went to turn it on around lunch time the blue light came on but the screen remained black. I've tried several times to turn it off and then back on again but the screen remains black and the on light remains on. I pulled the battery out and then put it back in and I'm having no luck. What should I do?
