What should I do if the laptop does not turn on? The laptop has ceased to turn on: causes and actions

For some people, a laptop is so necessary that when it does not turn on, they have a sense of hopelessness. If you turn on the laptop, and it does not show signs of life, then do not rush into panic. In this article, we'll talk about what can be done in the event of such a nuisance.

All problems with the laptop are divided into two groups: software and hardware. The first can be solved immediately, without getting up from the chair. This includes problems with programs, the operating system and BIOS setup. If the second appears, then repair is necessary.

So what if the laptop does not turn on? Below we describe the most common problems and tell you about the methods of their diagnosis.

Not included (no signs of life)

In most cases, this is a power problem. Check the tightness of the connections and the presence of voltage in the outlet. Usually, on a laptop and its adapter are indicator lights that are lit if there are no breakages. The most common problem in the power supply unit, which functions defective (there is no contact in the connector, bent or broken wires). Find out at which point the food is gone.

In order to avoid any difficulties in the future with the power connector, first insert the plug into the laptop, and then plug the power cord into an outlet. On the contrary, it should not be done, because when connecting the plug, a spark will appear, spoiling the contacts.

If the power supply and connectors are OK, and the notebook still does not turn on, check the battery. Pull out the battery and turn on the device without it. If that did not help, take the laptop to the service center.

The screen does not work, but fan noise is heard

Look closely at the monitor, it may just not work. Set the hot keys on your laptop to turn it on quickly and press them. But to accurately check what the problem is - in a screen or laptop, you'll need an external monitor. Connect it with a cable to the VGA output. If the picture appeared, then the problem is in the laptop screen. It is possible that the matrix burnt. In this case, you will have to take the device to a service center where you know exactly what to do if the laptop does not turn on.

Sometimes the cause of the failure is a discrete graphics card. This is especially true for laptops, which are often played. Due to contamination, poor cooling and improper use, the video card overheats and burns out. To prevent this from happening, do not play with the laptop on your stomach, on your knees and in any positions that block the ventilation holes. And be sure to use a cooling pad.

The notebook turned off and does not turn on

In this case, after a while, you can try to turn on the device. With a 90% probability, this is an overheating of the processor. It is necessary to clean the cooling system. After this, be sure to check the thermal system at maximum load. This test will determine how efficient the radiator grilles are. In case of malfunctioning of parts, they must be replaced, otherwise the processor or the north bridge will burn. Then the repair will cost much more.

Permanently shuts down or reboots

Even before the operating system loads, the laptop can be constantly rebooted. This is a hardware problem. Most likely, there was a short circuit in the south bridge - it overheated. This can happen due to a USB breakdown. Another reason is overheating of the processor due to a poor fit of the radiator or excess dust in the cooler. But this rarely happens, and if it does, then a clear sign is high fan speed. In this case, the laptop can be rebooted or shut down at different times. With poor power or lack of power, the device turns on, but the screen quickly dies due to a dead battery.

Hangs up showing screen saver

Above, we described the situation when the laptop stopped turning on. And what if he hangs? In this case, you may receive an initial screen saver or some text. Nothing happens next, the laptop writes about the error or squeaks. Most likely, this is a problem with the BIOS settings. You need to enter it and reset the settings. In different versions, this item may be in different places, but it is called identically and contains the keyword defaults. Then save the settings (save) and exit. Please note that the system may report an error, but further download is possible. You just have to press the F1 button. Usually this happens when the battery on the motherboard has sat down. At the same time, the BIOS settings and time are lost. It must be replaced (either alone or in a service center).

This can also include the situation where after the upgrade does not turn on the laptop or hangs. Here, reinstall the system. It's better to turn off the automatic updates feature and choose only those that are really needed from them.

What if the laptop does not turn on (or, more accurately, does not boot) after you've used the tips above? Then the problems can be due to RAM or hard disk. And this is much more serious. Some models of laptops do not have access to RAM. It is worth removing the straps and gently cleaning the contacts. The problem with the hard disk can be diagnosed by clicking it during the transfer of information.

Can not boot from disk

This can be signaled by screen captions in English. For example, Error loading operating system or something like that. To start, disconnect all external devices (USB flash drives, disks, etc.). Then reboot. If it does not help, then this is either a software or hardware problem with the hard drive. The first can be solved by contacting a service center where they know exactly what to do if the laptop does not turn on. The second is reinstalling the operating system.

Conclusion

So what if the laptop does not turn on? The reasons can be different. To begin with, it is worth considering at what point it happened. That is, what recent actions could lead to a breakdown. If it was a long game, it probably overheated the graphics card or other laptop chipsets. Here you will need a qualified repair. If a program was installed, and after restarting, the laptop did not turn on, then it is operating system errors.

The most common problems and methods for their diagnosis were described in the article. And finally: do not make rash conclusions and do not disassemble the laptop without having the relevant knowledge.
