Sometimes, at all, even among experienced computer users, there is a situation when the laptop does not turn on , and immediately the question arises - what to do. The reasons for this are very different and there are a lot of them, so let's start to understand.
Laptop does not turn on - causes and solutions
The simplest thing that could happen to your electronic assistant - he completely sat down battery. In this case, the laptop will not turn on without connecting the charger. But this is not a problem - the solution is elementary, and one should not panic at all.
The first thing to do when the laptop turns off and does not turn on is check its connection to the network, whether the plug or socket is moving away. And if the reason is not in the end of the charge, we move on.
What to do if the laptop does not turn on completely, that is, when you turn on the power button, you hear the work of HDD and cooler, but the download does not happen, that is, hangs, most likely, there was a malfunction in the work of Bios. It is necessary to reinstall it, and if you do not have the necessary skills for this, it is better to give the laptop to a service center.
If the laptop restarts and shuts down during operation, this can cause a fear of its serviceability. However, most often this is due to overheating, when the cooling system can not cope. This happens for a number of reasons:
- The laptop is on a soft surface, for example - on a blanket, a sofa, a pillow;
- The cooler and other inside of the notebook are dusty;
- the cooler needs repair;
- there is too much load on the processor and graphics card (for example, you played).
What if the laptop does not turn on at all? If there is absolutely no reaction to pressing the power button, this is most likely due to the power supply or the port for the charger. Most likely, the perpetrators of the malfunction were physical damage or voltage drop.
If the bulbs do not light up when you press the start button and you do not hear that the cooler has started, there may be several reasons for this:
- Burned power supply unit, a dead battery, its absence or breakage. And if the battery indicator still flashes several times when you press the power button, this clearly indicates the battery that was sitting down and the lack of recharging.
- No contact in the power connector either in the notebook itself or in the power supply.
- The presence of a problem in the power supply on the motherboard.
- The lack of firmware Bios or firmware "broken".
What should I do if the laptop does not turn on the screen?
So, probably your laptop turns on and works, but you do not see it because the monitor simply does not work. Look closely at it, perhaps you will see something on it, but because of the lack of illumination it seems completely dark. To turn on the backlight, you need to use hot keys, for example, Fn + F2, if you have Lenovo.
But the screen may not really work. A reliable way to verify the guilt of the screen can be by connecting the laptop to an external monitor via a VGA output. If the picture on it appears, then the problem is exactly in the laptop screen.
Often the cause of the malfunction is likely to be a discrete graphics card. If you like to play on a laptop, a bad cooling system, its dustiness and improper use of the computer can lead to overheating of the video card and its breakdown.
What if the Asus notebook does not turn on?
Best of all, the cooling system is built in Asus laptops. So they very rarely suffer from overheating. Accordingly, if the laptop firm Asus is turned on, there is hardly a reason in this. Most likely, the problem is related to nutrition.
