I have this laptop and after startup screen go white, i no see the POST screen. If i press Fn+F10 for screen change, i get the Windows bad shutdown screen where u choose Repair or Normal start. But after choose screen go back white. I checked for loose cabel, but everything right. External monitor dont work. If i try enter Bios, i hear beep but dont see the screen(screen change dont help). Any idea? (sorry my bad english).
