I have a Toshiba Qosmio F45-412. Everything was working fine last night. I was reading my email on my laptop. I was also watching a movie on tv while it was on and I let my battery completely drain and the laptop went blank. After attaching power cord and let charge for a few minutes I tried to turn on my laptop again. Now all it does is show the Qosmio and Intel logos with a download bar that fills then straight to a black screen with blinking curser in top left corner. No beeps or any noise and doesn't seem to be even reading the hard drive. Total time til curser about 10 seconds. And I have charged all night and also swapped cords. I also put in a recovery disc that came with laptop but no difference. PLease help if can, thanks!
