960GB Ultra II SSD dissapeared from BIOS

I’m having the same problem. My SSD disappeared after doing a forced shutdown (holding power button for 5 seconds). I’ve had to do the forced shutdown many times in the past because my laptop emerges from hibernation/sleep with a black screen and a dead keyboard. Computer has always rebooted fine until now. I’m going to plug the SSD into a desktop to see if it shows up there.
