I have a sony vaio model CG-61611L that will turn on (the power light is green and you can hear the inside running), but the screen will not show anything, is just black. I have tried turning it off and back on and removing the battery, no success.
Check your keyboard for a key with a VGA symbol(looks like a drawing of VGA connector). It would probably be an alternate function, used by holding down the FN key. Your laptop may be set to display to an external monitor.
Or I suppose alternatively, you could try connecting a monitor to your video out ports.
Thanks for the replies. I don't think the monitor is the problem. In a stroke of luck the screen started as normal, but once I logged in nothing but the task bar would load and the clicker would appear as if still loading. I waited about 15 min and nothing happened. I tried ctrl alt del, but the computer did not respond to anything. I turned it off and havent been able to make it work again. any ideas on what else it could be? thank you all again--
