Always remember to clean the monitor on a laptop every now and then. This is because a lot of dust accumulating on your monitor can end up resulting in the screen degenerating over time, and it could go on and become fairly useless with the passage of time.
Hence in order to extend the screens life, make you clean it regularly.
Close laptop with care
One of the most common ways for a laptop to get damaged or injured, is if the screen on the laptop is close with far too much force.
This tends to cause a lot of pressure to be applied on the screen and over a period of time, this pressure can lead to the screen cracking, developing display problems and even breaking if the force that is exerted on it is far greater than what should be used.
Use a support
Now a good way to make sure that the screen survives for a very long time is to offer it support when you are using it.
This may seem like a rather odd thing to do, since it is supposed to stand on its own. However, offering it support takes away a lot of pressure from the screen and its joints which is what actually leads up to the screen getting damaged.
So all you have to do is to support the screen against a wall or anything that may offer it support and you are good to go.
