Updated to the latest BIOS and still have this issue. Sometimes I can hit the fn + f6 (screen off and on button) and it somehow turns the screen on. But this doesn't always work and results with a hard powerdown with power button, then turning back on to fix. That is the only way I can fix it forsure. Try closing/opening lid, updating all the drivers, rolling back video drivers, powering down every time (which sucks), doesn't always work.
Maybe it's just my laptop? Any suggestons on how to fix this?
Doesn't always happen, but it happens often enough for me to actually come here and post this.
