You might have accidentally hit the external monitor key. Locate the Fn key, should be bottom left of the keyboard. Next look along the top row of keys and find the one for external monitor, it should have a rectangular screen looking icon on it. While holding down the Fn key, press that key and see if it comes back for you. If not then it's time to troubleshoot the display or GPU.
Darkened screen as you describe indicates a failing inverter. You can test this easily by plugging the laptop into an external monitor, if this works ok, then the inverter needs replaced, If it does not work, the problem is with the graphics chip / motherboard

Have you used the Fn button on your laptop and changed the video display Icon on the Blue Function keys. You need to change the display wait a few seconds for it to take affect. There are several modes try them all so you know how to use them.
This generally indicates that a sector in the hard drive has failed, and the hard drive will need to be replaced. With a bad sector the drive reads to the point of the bad sector and past the bad sector, but can't put the info together, so it tries to boot, but can't. Unfortunately, your only option is replacing the hard drive.
i would try this first goto device manger in your computer and find the video card in the list and see if it needs updated if this does not work it might be that the video card might be bad but it sounds like a video card update driver is needed
Go to the BIOS menu and select the Main Tab... see if the computer sees your drive. If not send it to the manufacturer or look to see if you can get to the HD without cracking open the main case to the laptop if you can... check the connection from the HD to the connectors to the motherboard
