Failures of laptops happen quite often. The reason is prosaic - the laptop is a portable device, so it is quite fragile and it can be easily damaged by an accident. Child or dog can drop it from the desktop or the couch - if you're unlucky, the screen may break. Does this mean that you have to buy a new computer? Absolutely not! You should take your broken laptop to the trusted computer service, or you can check if the warranty does cover this type of failure. Do not panic - you can always find a solution that will not ruin your wallet.
The form of a traditional laptop computer is a clamshell, with a screen on one of its inner sides and a keyboard on the opposite. It can be easily folded to conserve space while traveling. The screen and keyboard are inaccessible while closed. Devices of this form are commonly called a 'traditional laptop' or notebook, particularly if they have a screen size of 11 to 17 inches measured diagonally and run a full-featured operating system like Windows 10, OS X or Linux. Traditional laptops are the most common form of laptops, although Chromebooks, Ultrabooks, convertibles and 2-in-1s (described below) are becoming more common, with similar performance being achieved in their more portable or affordable forms.
