There are various problems your laptop can have from your screen having no image to there being clicking noises coming from your laptop.

One example of an issue your laptop can have is your laptop showing no image. This is a very common problem with laptops and computers when powering it on the screen is completely black or shows no image. If this occurs always check if it is completely powered on. Meaning the fan is spinning also check the LEDS. As you can see above the LEDS are glowing and the fan is functioning so It would have to be another issue. To make sure check your other hardware. Usually if your screen has no image the reason is ram. Use your Philips screwdriver to remove the nails and take off the covering. Then you should see the ram built on the motherboard close to the wireless card. It depends on the computer you have and its specifications but usually people have two sticks of ram. To solve this issue of no image make sure to replace the ram or make sure nothing is in the way of it. Or even take it out and put it back in.
