video/KB issue

[altecXP]

Randomly my macbook will boot and have no video or KB.trakpad input.

I wil have to hook up an external display and mouse and keyboard to be able to log in and work.

its a 2011, has anyone sen this before? The Macbook boots then shows a blue screen and it fades to black and then will not display video on my macbooks LCD, but will on an external display.

THink I figured it out. It seems to do with the order of how I put it to sleep/disconect cables.

If I booted it with the mouse/keyboard and external display, then disconnected the mouse, then keyboard, then external display it works just fine.

Really weird.
