Laptop does not turn on

Today, conventional stationary PCs are often replaced by laptops, but, like all technology, these devices tend to break. If the laptop does not load, do not panic, you need to find the cause and fix it. Most often, you can restore the operation of the equipment yourself, if you know how to troubleshoot.

Why the laptop does not turn on

The reasons are many. Most eliminate is not difficult, but certain faults may require the help of specialists.

The main reasons why the laptop does not load are the following:

1. Problems with the winchester.
2. Power problems.
3. Incorrect settings or BIOS failure.
4. Video card breakdown.
5. OS crash.
6. Overheat.
7. Violation of the RAM.
8. Failure of the processor.
9. Windows crash.

If the laptop starts to emit a squeaky sound during bootup, this indicates overheating or malfunctioning of the device’s RAM. If there is some knowledge, then you can try to determine for yourself why this happened. What you need to first wipe the dust. If the failure is not fixed, you need to replace the RAM with the working modules.

BIOS failure may occur due to improper updates. If before the occurrence of a malfunction the user made such an operation, you need to contact the repair shop.

Failures in Windows lead to the fact that the system does not boot. First you need to determine the cause and try to fix it. In addition, you can reinstall the OS or perform a system restore.

How to find and eliminate the cause

Most often, the problem can be corrected by yourself. First you need to remember, after which the device ceased to turn on correctly, whether any errors appeared, whether any programs were loaded. Often this allows you to determine the fault.

Power failure

These problems are not rarely caused by the inability to start the laptop. Despite the fact that such a fault seems serious, it is usually very easy to identify and get rid of it.

Major faults:

1. Violation of wire integrity.
2. Incorrect connection of the power supply.
3. Violation of the power supply circuit.
4. Failure of the BP.
5. Battery malfunction.

Usually, with these faults, the device power indicator does not light up. First you need to determine the correctness of the connected power supply and the fact that the wire is plugged into the network.

Damage to the cord can be caused by many reasons, among the most frequent: careless use or pets that can cut through the cable. This can be determined visually.

Also a common cause is a rechargeable battery. Sometimes, if the battery is inoperative, the laptop does not turn on even through the 220 V network. You can try to get the battery and plug the device into an outlet without it.

The power supply breaks often on any gadgets. Without charging, the battery will sit down after a while, after which the PC will not turn on. Find out about the breakdown of the power supply is simple. You need to insert another charge from a working laptop.

Winchester problems

If the hard drive fails, the mobile PC will not turn on, the device hangs on the Windows splash screen. Sometimes the system notifies about the HDD error, for example, there is no disk for loading.

Anyway, you can go to the BIOS, where to check whether the hard drive is determined. If it is available, you can turn on the laptop from the boot disk and determine the cause.

Video card crash

Causes are usually overheating, mechanical deformations after a fall, etc. The behavior of the PC may be different. If the video card is broken, the pictures on the screen will not appear, but you can hear the work of the cooler.

Set the cause itself will not work. An attempt to repair a video card is almost impossible, it needs replacing.

After cleaning

Sometimes it happens that after cleaning the device does not turn on. And the cooler can work or a squeak will be heard.

Cleaning the device requires disassembling the laptop. The first thing to do to solve the problem is to open the case again and check all the connections of the elements.

If during cleaning the dies of RAM were removed, then you need to re-remove them, check the terminals and set back. You also need to check whether the laptop turns on when the drive is disconnected and the drive.

After update

If updates are not correct, the PC may not boot. If errors began to appear after updating the software or Windows, then you can roll back the system through safe mode, reinstall the OS, or return to the factory settings if this is provided for in the laptop.

Spontaneous outages

Sometimes the device can turn on and work for some time without any problems, and then turn off spontaneously. There are several reasons for this:

1. Overheat.
2. Breakage of parts.
3. Virus programs.
4. System crashes.

Overheating is the most common cause of spontaneous outages and restarting a laptop. After a while, it can disable the device completely. To prevent this, you need to regularly clean the laptop, change the thermal grease.

The breakdown of various elements also rarely appears due to overheating. If periodic cleaning was not performed, then the appearance of this situation increases by several times.

Virus programs can disrupt the OS, as a result, the computer can shut down itself. To fix the problem, you need to scan the system with an antivirus.

Software failures also often lead to spontaneous shutdown of the PC. It is necessary to determine the cause using the codes appearing on the monitor at the time of the failure. Then the problem program needs to be removed.

Initialization fails

If the LEDs turn on, the fan is active, but there is no access to the hard drive (the corresponding diode does not light up), then initialization failed.

Likely reasons:

1. Violation of the north or south bridge.
2. Incorrect work BIOS.
3. Failure of the processor, RAM or video card.

Windows does not load

The inability to load the operating system is often not related to the presence of hardware failures. Therefore, you can try to reinstall the OS, roll back to the operating state of the laptop, or use the factory recovery tools.

With hardware malfunctions, as a rule, the inability to enter the operating system is due to problems with the hard drive. In this case, you need to install a new disk. Before that, you can try to make a diagnosis with special programs by performing a boot from external media.

When you need to contact specialists

Modern mobile PCs emit quite a lot of heat energy at work. If the cooling system is very dusty or defective, overheating begins, after which some elements of the PC may break. It’s most often impossible to fix this problem yourself; you need to contact the workshop.

The main elements of a PC that fail when overheated:

1. Video card
2. CPU.
3. Bridge graphics card.
4. Winchester.

Mobile computer breakdowns are numerous. You can identify and get rid of many yourself. But if the device beeps, flashes or turned off and does not turn on at all, then it will most likely be able to fix it only in the workshop.
