Today, about a third of the world's population has any computer equipment. However, many do not even know what to do when their “iron” fails.
Why the laptop does not turn on: the main reasons for the failure
Before the user starts working ona laptop, a laptop computer performs a variety of boot operations: turn on, initialize the system, display an image on the screen, load the operating platform.
Many users like to use the phrase:"The laptop does not turn on at all." What is behind these words? Maybe this suggests that the laptop does not make noise, no indicators on it are functioning, it does not make any sounds.
The reasons why the laptop does not turn on can be several:
Burned power supply.This is perhaps one of the most common causes of failure. How to check it? You just need to connect an identical power supply. If no indicators at the same time do not light up on the body of the laptop, you will most likely have to buy a new power supply.
No battery power.How to check it? You need to connect the laptop to the network with the battery pulled out. If at the same time it starts to work in its normal mode, then you only need to replace the battery.
Out of order motherboard. Independently eliminate the problem does not work. There may be a lot of breakdown options, 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 is loading up to a certain point, when the indicator should turn on the hard disk. There can be several reasons for such a breakdown: a malfunction of the processor or RAM, or the north bridge, or BIOS firmware, etc.
Mechanical damage to the housing can alsolead to serious problems. With significant physical exertion may damage the motherboard, hard drive, display and other components. In this case, it will be necessary not only to repair the laptop case, but also its components.
Why doesn't the laptop display turn on?
When the screen does not turn on in the laptop (only a black background is visible), but the cooler is heard, the OS is booting, all the necessary indicators are lit, then the problems with the matrix are likely.
Even if with a laptop fora long time there are no problems, this is not a reason not to monitor its performance and not to carry out maintenance work. Believe me, the day will come when upgrading and repairing laptops will be necessary.
There are several reasons for upgrading the hardware: the OS loads for a long time, programs hang, there is not enough RAM or memory, computer games are loading slowly, etc.
If the question arose why the laptop does not turn on, it is better to try to understand the causes of these problems. And, if possible, try to fix the problem yourself.
