Today, about a third of the world's population has some kind of computer equipment. However, many do not know what to do when their “hardware” fails.
Why the laptop does not turn on: the main causes of failure
Before a user starts working on a laptop, a portable computer performs a number of loading operations: turning on, initializing the system, appearing an image on the screen, loading the operating platform.
And at every stage, a breakdown can occur. Why the laptop does not turn on is difficult to determine on your own.
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 is not noisy, no indicators on it are functioning, it is not making any sounds.
There may be several reasons why the laptop does not turn on :
The power supply burned out. 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 light up on the laptop case, then most likely you will 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 removed. If at the same time it starts to work in its normal mode, then only a battery replacement will be required.
The motherboard is out of order. You can’t fix the problem yourself. There can be a lot of breakdown options, so it is better to take the laptop to a service center right away.
No initialization. How is it shown? When the laptop starts, it downloads to a certain point when the hard disk indicator should light up. There may be several reasons for this failure: a processor or RAM malfunction, or a north bridge, or BIOS firmware, etc.
Mechanical damage to the case can also lead to serious problems. With significant physical exertion, the motherboard, hard drive, display and other components may be damaged. In this case, it will be necessary not only to repair the laptop case, but also its components.
Why does the laptop display not turn on?
When the screen does not turn on in the laptop (only a black background is visible), but the cooler is heard, the sound of loading the OS is heard, all the necessary indicators light up, then most likely there are problems with the matrix.
How to check what is malfunctioning? You can connect an external monitor. If everything is in order with the image on it, it means that the display definitely broke in the laptop.
Even if there are no problems with a laptop computer for a long time, this is not a reason not to monitor its performance and not to carry out preventive work. Believe me, the day will come when the modernization and repair of laptops will be simply necessary.
There are several reasons for upgrading hardware: the OS takes a long time to load, programs freeze, there is not enough RAM or memory, computer games are slowly loading, 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 problems yourself.
