Today, about one third of the world's population has any kind of computer equipment. However, many do not know what to do when their "hardware" goes out of order.
Why the laptop does not turn on: the main reasons for the failure
Before the user starts working on thelaptop, the laptop performs a number of boot operations: the inclusion, initialization of the system, the appearance of the image on the screen, the loading of the operating platform.
Many users like to use the phrase:"The laptop does not turn on at all." What is behind these words? Maybe it says that the laptop is not noisy, no indicators on it are functioning, no sounds are emitted.
The reasons why the laptop does not turn on, there may be several:
The power supply unit was burnt.This, perhaps, is one of the most common causes of breakdown. How can I check this? You just need to connect an identical power supply. If no indicators do not light up on the laptop, you will most likely need to buy a new power supply.
No battery power.How can I check this? It is necessary to connect the laptop to the network with the battery removed. If at the same time it starts to work in its normal mode, then it will only need to replace the battery.
The motherboard failed. It will not be possible to solve the problem yourself. There are a lot of options for crashing, so it's better to take the laptop to the service center right away.
No initialization.How is it shown? When you start the laptop, it loads until a certain point when the hard drive indicator should light up. There can be several reasons for this breakdown: a malfunction of the processor or RAM, or the north bridge, or BIOS firmware, and so on.
Mechanical damages can alsolead to serious problems. With significant physical exertion, the motherboard, hard drive, display and other components can be damaged. In this case, it will be necessary not only to repair the laptop's case, but also its components.
Why does not the laptop display turn on?
When the screen does not turn on in the laptop (only the black background is visible), but the cooler's operation is audible, the OS boot sound is heard, all the necessary indicators are lit, then, most likely, problems with the matrix.
Even if with a laptop duringFor a long time there are no problems, this is not a reason not to monitor its efficiency and not to carry out preventive work. Believe me, the day will come when modernization and repair of laptops will be simply necessary.
There are several reasons for the hardware upgrade: the OS boots for a long time, the programs hang, the operating or memory memory is not enough, computer games are slowly downloaded, and so on.
If there was a question, why the laptop does not turn on, it is better to try to understand the reasons for the appearance of these problems. And, if possible, try to solve the problem yourself.
