A laptop (also a laptop computer) is a small, portable personal computer. Laptops combine all the input/output components and capabilities of a desktop computer, including the display screen, small speakers, a keyboard, hard disk drive, etc. Laptops can be powered either from an internal battery or by an external power supply from an AC adapter. Laptops are commonly used in a variety of settings, such as at work, in education, for playing games, Internet surfing, for personal multimedia, and general home computer use. It is very easy to carry with us as it's small and compact. However, laptops are often out of battery which prevents us from working for a long time.

No one can deny this! Indeed it is. Although there are so many tablets and smart phones today that are almost as useful as laptops, they still lose a long way to develop. Laptops "eat off" the tablet computer in terms of configuration as well as high performance processing applications. With their physical keyboards, these laptops are considered a big plus. Because according to the majority of users, they feel that the laptop's keyboard is easier to use than the touch keyboard. Because with the laptop keyboard you can operate faster and more accurately, perform the job more accurately than the error-prone touch screen. The average screen size of a laptop is also about 13 inches, slightly larger than the 10 inch size of a tablet, there is no reason why users turn to face the laptop when it is large, looking wide, quick and efficient operation to handle work effectively. Laptops are also designed with thin, light, and colorful colors for users to choose from. It is also important that when using a laptop you also do not have to worry too much about accidentally scratching or damaging the screen because the replacement problem is not too difficult as when turning off or the smartphone's touch screen.

Laptops (laptops) are more and more popular and become "indivisible objects" of many people. However, you should be careful: similar to cell phones, laptops also have a significant impact on health. Here are six common health hazards associated with laptop use, according to experts:

1. Back pain
Back pain is a health disorder that occurs when you regularly sit with your back arched while using a laptop. Some people like to lie down and put the laptop on their stomach to manipulate, causing the back to be bent for a long time, which is also the cause of back pain.
2. Loss of vision
Usually, when using a laptop with concentration, you rarely blink, making your eyes dry. Chronic dry eye conditions can affect eye health and, as a result, impair your vision. To prevent this risk, when using a laptop, be sure to blink frequently and take your eyes off the screen from time to time, looking at a distant object for a few seconds.
3. Neck pain
Most people often have to bow when using a laptop. This position lasts for a long time will cause neck muscle stiffness, which is the cause of chronic neck pain.
