This morning when tried to wake my laptop from sleep mode it was dark so I did a hard shutdown. When I tried to boot up I got the error "Primary disk drive not found" "No boot device available" "No bootable devices". This happened when I first got this laptop but somehow I remember getting it started in safe mode and then shutting down and it started ok and has worked fine ever since. I am currently on the road and my company help desk says there's nothing they can do and I need to bring in the laptop. Are they right?
