For some people, a laptop is such a necessary thing that when it does not turn on, they feel hopeless. If you turn on the laptop, and it does not show signs of life, then do not rush to panic. In this article, we will talk about what you can do if such trouble occurs.
All laptop problems are divided into two groups: software and hardware. The first can be solved immediately without getting up from your chair. This includes problems with programs, the operating system, and BIOS settings. If the second ones appear, then repairs are needed.
So what to do if the laptop does not turn on? Below we describe the most common problems and tell you how to diagnose them.
Does not turn on (no signs of life)
Most of the time it's nutritional problems. Check the tightness of the connection of the contacts and the presence of voltage in the socket. Usually, there are indicator lights on the laptop and its adapter that light up if there is no breakdown. Most often, the problem is in the power supply, which is not functioning properly (there is no contact in the connector, bent or broken wires). Find out exactly whenNo power.
In order to avoid problems with the power connector in the future, first insert the plug into the laptop, and then the power cord into the outlet. On the contrary, you should not do it, because when the plug is connected, a spark will appear, damaging the contacts.
If everything is in order with the power supply and connectors, 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 a service center.
Screen does not work, but fan noise is heard
Take a closer look at the monitor, maybe the backlight just doesn't work. Install hotkeys on your laptop to quickly turn it on and press them. But 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 appears, then the problem is in the laptop screen. It is possible that the matrix burned out. In this case, you will have to take the device to a service center, where they know exactly what to do if the laptop does not turn on.
Sometimes the discrete graphics card is the cause of the problem. 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 avoid this, do not play with the laptop on your stomach, on your knees, or in any position that blocks the ventilation holes. And be sure to use a cooling pad.
During work, the laptop turned off and does not turn on
In this case, after some time, you can try to turn on the device. With a probability of 90% this is an overheating of the processor. The cooling system needs to be cleaned. After that, be sure to check the thermal regime system at maximum load. This test will determine how efficient the heat pipes of radiators are. In the event of a malfunction of the parts, they must be replaced, otherwise the processor or the northbridge will burn out. Then the repair will cost much more.
Permanently shutting down or restarting
Even before loading the operating system, the laptop may constantly reboot. This is a hardware problem. Most likely, there was a short circuit in the south bridge - it overheated. This can happen due to USB breakdown. Another reason is overheating of the processor due to 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 speeds. In this case, the laptop may reboot or turn off at different times. If the power supply is poor or absent, the device turns on, but the screen quickly goes out due to a dead battery.
Freezes while showing splash screen
Situations were described above when the laptop stopped turning on. What to do if it freezes? In this case, an initial splash screen or some text may appear. Nothing happens next, the laptop writes about an 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 itemmay be in different places, but it is named the same and contains the defaults keyword. 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 dead. At the same time, BIOS settings and time are lost. It needs to be replaced (either by yourself or at a service center).
This also includes the situation when the laptop does not turn on or freezes after the update. Reinstalling the system will help here. It's better to turn off automatic updates and choose only those that you really need.
What to do if the laptop does not turn on (more precisely, it does not boot) after you have used the above tips? Then the problems may be due to RAM or hard drive. And this is much more serious. For some laptop models, access to RAM is not closed. It is worth removing the straps and carefully clean the contacts. A problem with a hard drive can be diagnosed by its clicks during the transfer of information.
Can't boot from disk
This can be signaled by inscriptions from the screen in English. For example, Error loading operating system or something similar. 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 problem of the hard drive. The first can be solved by contacting a service center, where they know exactly what to do if the laptop does notturns on. The second is by reinstalling the operating system.
So what to do if the laptop does not turn on? The reasons may be different. To begin with, it is worth considering at what point this happened. That is, what last actions could lead to a breakdown. If it was a long game, the graphics card or other laptop chipsets probably overheated. This will require a qualified repair. If some program was installed, and after rebooting the laptop did not turn on, then these are operating system errors.
The most common problems and how to diagnose them were described in the article. And finally: do not jump to conclusions and do not disassemble the laptop without proper knowledge.
