Hi everyone,

I'm dealing with an intermittent problem and can't find a solution. Sometimes my notebook starts up and everything works fine. However, after I turn it off and try to turn it on again, the motherboard starts, but the screen stays black. It seems like the notebook freezes and a green LED with a light bulb icon stays on.

Thanks in advance!
