As the most laptop users know, there are many problems with laptop screen we can meet. For example, the laptop screen is easily damaged by some hard things and there is nothing on the laptop LCD screen sometimes when we turn on the PC motherboard. When the laptop screen is damaged, we can only replace a brand new one to make the laptop work well for us. But when we can't see anything on the laptop screen after we turn on the laptop sometimes, we can check whether the laptop screen really can't work and needs to be replaced. The following are the steps: First, remove the laptop screen and install it to some other laptops to check whether the laptop screen itself has some problems. Here, you need to make sure the laptop model of the laptop you install the screen is the same to your original one or is compatible with yours at least. Otherwise there is nothing seen on the laptop screen even through your laptop screen is good. Second, take graphics card out to check whether there is much dust. If so, please clean it, and then install it and have a try to turn on the laptop again. If the laptop screen works well, that means the laptop screen is good. The problem is caused by the dusty graphics cards. Third, check your laptop AC adapter if you haven't found the problems after you have checked with the above ways. If the output of the laptop AC adapter is too low, the laptop can't be powered on. So there is nothing on the laptop LCD screen. If you still can't find the problem with all the above ways, you'd better take your laptop and all the accessories to the nearest local laptop repairing shop to ask the special person to help you to check and find the exact problem.
