For some people, the laptop is so necessary.the thing is that when it doesn’t turn on, they have a feeling of hopelessness. If you turn on the laptop, but it does not show signs of life, then do not rush into panic. In this article, we will talk about what can be done in the event of such a trouble.
All problems with a laptop are divided into two groups:software and hardware. The first can be solved immediately, without getting up from the chair. These include problems with programs, the operating system, and BIOS setup. If there are second, then repair is necessary.
So what if the laptop doesn't turn on? Below we describe the most common problems and describe the methods of their diagnosis.
Not included (no sign of life)
In most cases, these are nutritional problems.Check the tightness of the contacts and the presence of voltage in the outlet. Usually, on the laptop and its adapter there are indicator lamps that burn if there are no breakdowns. Most often, the problem is in the power supply, which functions incompletely (there is no contact in the connector, kinked or broken wires). Find out exactly at what point the power goes.
That in the future there were no difficulties withpower connector, first insert the plug into the laptop and then the power cord into a power outlet. On the contrary, you should not do it, because when a plug is connected, a spark will appear that spoils the contacts.
If the power supply and connectors are fine,and the laptop still does not turn on, then check the battery. Remove the battery and turn on the device without it. If this does not help, take the laptop to the service center.
The screen does not work, but fan noise is heard
Присмотритесь к монитору, возможно, просто не backlight works. Install hot keys on your laptop to quickly turn it on and press them. But in order to check exactly what the problem is - in the screen or laptop, you 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 burned down. In this case, you have to take the device to a service center, where you know exactly what to do if the laptop does not turn on.
Иногда причиной неисправности является дискретная video card. This is especially true for laptops, which are often played. Due to pollution, poor cooling and improper use, the video card overheats and burns out. To prevent this from happening, do not play with your laptop on your stomach, on your knees or in any position where ventilation holes are blocked. And be sure to use a cooling pad.
The laptop turned off during operation and does not turn on.
In this case, after some time the deviceYou can try to include. With a 90% probability, this is processor overheating. 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 heat-sink radiators are. In case of failure of parts, they must be replaced, otherwise the processor or the north bridge will burn. Then repair will cost much more.
Permanently shut down or reboot
Even before loading the operating system, the laptop canconstantly reboot. This is a hardware problem. Most likely, there was a closure in the south bridge - it overheated. This may happen due to USB breakdown. Another reason is overheating of the processor due to poor fit of the radiator or excessive dust in the cooler. But this rarely happens, and if it does, a clear sign is high fan speed. In this case, the laptop can be restarted or turned off at different times. With poor power or lack of it, the device turns on, but the screen quickly goes dead due to a dead battery.
Hangs showing screensaver
We have described the situations when I stoppedturn on the laptop. And what if it hangs? At the same time, the initial screen saver or some text may appear. Then nothing happens, the laptop writes about the error or beeps. Most likely, this is a problem with the BIOS settings. You need to enter it and reset the settings. In various versions, this item may be in different places, but it is called the same and contains the keyword defaults. Then save the settings (save) and exit (exit). Please note that the system may report an error, but further loading is possible. You just need to press the F1 button. This usually happens when the battery on the motherboard is low. At the same time, BIOS settings and time are lost. It must be replaced (either independently or in a service center).
This may also include a situation where afterThe update does not turn on the laptop or freezes. Here will help reinstall the system. It is better to disable the automatic updates feature and select only those that are really needed.
What if the laptop does not turn on (more precisely,not loading) after you use the above tips? Then the problems may be due to RAM or hard disk. And this is much more serious. Some models of laptops access to RAM is not closed. It is necessary to remove the strips and carefully clean the contacts. A problem with a hard disk can be diagnosed by clicking it during the transfer of information.
Does not boot from disk
This can be signaled by screen captions.English language. For example, Error loading operating system or something like that. First, turn off all external devices (flash drives, disks, etc.). Then reboot. If it does not help, then this is either a software or hardware hard drive problem. The first can be solved by contacting the service center, where they know exactly what to do if the laptop does not turn on. The second is by reinstalling the operating system.
Conclusion
So what to do if the laptop does not turn on?The reasons may be different. For a start, it is worth considering at what point it happened. That is, what recent actions could lead to damage. If it was a long game, the video card or other laptop chipsets probably overheated. Here you will need a qualified repair. If any program was installed, and after rebooting the laptop did not turn on, then these are operating system errors.
The most common problems and methods of their diagnosis have been described in the article. And finally: do not make rash conclusions and do not disassemble the laptop without the relevant knowledge.
