Sometimes it turns out that although the power indicator is on, the laptop does not turn on at the same time. Why is this happening? What should I look for? What may be required in order to rectify the situation? Understanding these questions is not as easy as it seems. After all, a computer is unpredictable equipment. Faults, especially when turned on, can be the result of many failures. Some immediately go to service centers. Doing so is not recommended. It is advisable to first try to diagnose the problem yourself. It may be possible to cope with the situation without assistance.
Video card
The power indicator is on, the laptop does not turn on? The reasons for this phenomenon are different. The first thing you might think is a malfunctioning video card. In the case of a stationary computer, it is simple to detect and fix a breakdown or failure - just remove this component and connect it to another machine.
But in the case of laptops will have to try. It is recommended that if you suspect a breakdown or malfunction of the video card, contact service centers for help. Or call some system administrator. You can also try to diagnose the problem yourself. Typically, the laptop itself turns on - you can hear the cooler. But there is no picture on the screen. Sometimes you can even hear the loading of the operating system.
Screen malfunction
What's next? The power indicator is on, the laptop does not turn on, but can a problem with the video card be eliminated? It is likely that the device has broken or damaged the monitor. An extremely rare phenomenon, which in practice still takes place.
If the display breaks, then most likely the “symptoms” of the breakdown will turn out to be exactly the same as in the case with the video card. There will be no image on the monitor, but the sound of turning on the operating system will appear.
It is not possible to solve this problem independently. If only through the acquisition of a new laptop. In such circumstances, you can contact the service center. Maybe the display can be repaired. But usually devices after such repairs do not work for a long time. In the end, you still have to replace the laptop with a new one.
Bios
The following situation can be fixed without assistance. The power indicator is on, the laptop does not turn on? The main causes of this phenomenon are either a failure or a reset.
It is likely that the settings of "BIOS" were lost. Because of this, a problem was studied on the laptop. In this situation, it is recommended to completely reset the BIOS. After that, the computer should work in full force.
Lack of components
What else could be the result of the problem? If we are talking about a new laptop that has not worked before, do not rule out the absence of any components. If the machine itself turns on, but nothing is displayed on the screen, while the CapsLock and NumLock buttons do not go out, most likely the BIOS does not initialize.
It is likely that the laptop does not have a processor or RAM. Or, when it comes to a previously functioning device, the reason may lie in the breakdown of the listed components.
HDD
Sometimes it happens that although the power indicator is on, the laptop does not turn on, but previously it worked normally, the hard drive becomes the cause of the problem. A small glitch - and the computer will refuse to start. But at the same time, the power button will light. You can also notice the operation of the fan in normal mode. The buttons "Nam Lock" and others at the same time light up and go out, as expected.
It is recommended to disassemble the laptop and disconnect the hard drive. In this state, try to turn on the device again. Did not help? Then you can again neatly attach the component. If the problem was in a glitch, then now it will disappear.
Battery
The power indicator is on, the laptop does not turn on? Diagnosing an incident requires certain knowledge from the user. Yes, do not immediately give the computer for repair. But it should be borne in mind that most of the problems are usually solved with the help of a professional.
You can independently resolve the situation if, for example, the problem lies in the battery. It is likely that she was discharged. Then it is enough to connect the power (wire) to the network and to the machine. Next, try to turn on the device again. It’s better to wait a few minutes before pressing the laptop’s power button. Allow the battery to get a little charge. A similar technique is quite effective.
Some recommend removing the battery from the laptop completely and then connecting the power cord. Only then turn on the computer and watch the situation. If the machine is fully operational, then nothing more needs to be done. Otherwise, you have to look for the source of the problem elsewhere.
As practice shows, battery problems or a discharged laptop are common. Perhaps the safest and most easily removable without assistance.
Short circuits
Samsung laptop not turning on? Does the power indicator light on, does the cooler work? The next scenario is one of the rarest. And to independently diagnose it is almost impossible.
The malfunction under study can occur if the south or north bridge in the laptop is damaged. Why is this so? Bridge problems are caused by various methods. For example, by short circuit due to temperature differences. If, for example, a USB port is damaged on a laptop because of this, the occurrence of the problem under study is likely.
There is only one fighting method - repair of damaged components. The most effective way is to buy a new computer. After all, on laptops, rarely repaired components then work for a long time. Here, each user independently decides what to do.
Viruses
If the laptop does not turn on (the power indicator is on) after the device has been functioning for some time, you should think about the effects of viruses on the machine. Computer infection often leads to the fact that the computer stops working in normal mode. Sometimes it comes to damage by BIOS viruses. Accordingly, there will be a problem with turning on the laptop.
It is unlikely that you can fix the problem yourself. As in most of the previously mentioned cases, it is better to take the computer to a service center. There they will help not only return the laptop to working capacity, but also treat it from viruses.
Fortunately, such a scenario is rather rare. But it should not be ruled out. Especially if the user himself admits the presence of viruses in the computer. Sometimes problems turning on the laptop arise after the treatment of the operating system. Then it is enough to reinstall first “BIOS”, then OS. After that, no problems will bother you anymore.
Instead of a conclusion
What can be summed up? It should be noted that in most cases both diagnostics and troubleshooting are reduced to contacting a service center. Most often, many do this. After all, a laptop is an extremely complex device. Repairing it yourself is not as easy as a stationary analogue.
If you understand why the computer does not turn on, it did not work out, you can immediately contact specialized centers. If there is a suspicion of any particular problem, it must be reported to the service employees.
