Daniel turned on his laptop and the screen is dead. Rich says to look at the screen up close and see if he can barely see the image. If he can, then that indicates the backlight is bad. If there's nothing at all, then it could be a bad motherboard. Either way, it's time to get a new laptop, because repairing a laptop usually costs more than it's worth to buy a new one.
One thing he can try is to connect it to an external monitor via HDMI and see if he can see something. If he can, then the computer is OK, but the screen is dead.
