Hope this helps...

If you can restart it and it starts up fine, then I would go into the power settings and disable sleep mode. Every computer is different on how to wake a sleeping computer, so you could read through your manuals and find out for yours, but I just disable sleep mode on all computers so i dont have to hassle with it.

u have to aigain press ur sleep button tehen he will be wake uo
or power off ur pc & restart its

Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.
