For some people, a laptop is such a necessary thing that when it does not turn on, they have a feeling of hopelessness. 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 when such a nuisance occurs.
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 latter appear, then repair is needed.
So what if the laptop does not turn on? Below we describe the most common problems and talk about how to diagnose them.
Does not turn on (no signs 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 lights that are on if there are no breakages. Most often, the problem is in the power supply, which functions inferiorly (there is no contact in the connector, bent or broken wires). Find out at what point the power is lost.
So that in the future there will be no difficulties with the power connector, 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 you plug in the plug, a spark will appear that spoils the contacts.
If everything is in order with the power supply and connectors, but 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; the backlight may simply not work. Install hot keys on your laptop to enable it quickly and press them. But in order to verify exactly what the problem is - in the screen or laptop, you will 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 cause of the malfunction is a discrete graphics card. This is especially true for laptops that 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 in which the ventilation openings are blocked. And be sure to use a cooling pad.
During operation, 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. It is necessary to clean the cooling system. After this, be sure to check the thermal regime at maximum load. This test will determine how efficient the heat pipes of radiators are. If parts fail, they must be replaced, otherwise the processor or the north bridge will burn . Then the repair will cost much more.
Constantly shuts down or reboots
Even before loading the operating system, the laptop may constantly reboot. This is a hardware problem. Most likely, there was a circuit in the south bridge - it overheated. This may happen due to a USB breakdown. Another reason is overheating of the processor due to poor fit of the heatsink or excess dust in the cooler. But this rarely happens, and if it happens, then a clear sign is the high fan speed. In this case, the laptop can reboot or shut down at different times. If the power is poor or lacking, the device turns on, but the screen quickly goes out due to a dead battery.
Hangs up showing screen saver
Above were described situations when the laptop stopped turning on. But what if it freezes? In this case, an initial splash screen or some text may appear. Then nothing happens, the laptop writes an 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 the same and contains the defaults keyword. Then save the settings and exit. Please note that the system may report an error, but further download 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 must be replaced (either on its own or in a service center).
This also includes a situation where after the update the laptop does not turn on or freezes. Reinstalling the system will help here. It’s better to turn off the automatic updates feature and select from them only those that are really needed.
What should I do if the laptop does not turn on (or rather, does not boot) after you use the tips listed above? Then the problems may be due to RAM or hard disk. And this is already much more serious. On some laptop models, access to RAM is not closed. It is worth removing the trims and carefully cleaning the contacts. The problem with the hard disk can be diagnosed by clicking on it during the transfer of information.
Not loading from disk
This may be signaled by screen captions 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 doesn’t help, then this is either a software or hardware problem of the hard disk. 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 by reinstalling the operating system.
Conclusion
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 recent actions could lead to breakdown. If it was a long game, the video card or other laptop chipsets probably overheated. A qualified repair will be needed here. If some program was installed, and after restarting the laptop did not turn on, then these are 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 the appropriate knowledge.
