If the laptop does not turn on at the next start, this may indicate either a minor problem that even an inexperienced user can handle or a serious breakdown. In this situation, the main thing is not to panic, but to try to diagnose the cause and deal with it. However, not everyone is a computer wizard, so before taking any action, it is worth studying the types of faults and learning how to deal with them. In this article, we have a complete guide on diagnostics and troubleshooting of laptops.
Hardware Causes of Malfunctions and How to Solve Them:
Due to the compact design and, the presence of a lot of small parts in laptops, there are often problems with components. Therefore, in order to avoid damage, it is worth remembering the careful handling of the case, as well as carefully monitoring the device during transportation. If nevertheless, a hardware malfunction has manifested itself, it is worth diagnosing the cause and trying to fix the breakdown.
The most common reason why the laptop does not turn on is a power supply failure, as a result of which the battery simply does not charge. It may be damaged due to prolonged use or broken cable. It is also sometimes associated with high temperatures and short circuits.
In this case, you just need to replace the power adapter or cable with a new one. It is worth remembering that the purchase and use of cheap and non-original power supplies can also lead to malfunctions, for example, melting of the outlet.
Hard Disk Failure:
Damage to the hard drive is associated not only with the appearance of a black screen on a laptop but also with the possible loss of data and programs contained in the storage. Drives are equipped with SMART technology, so they themselves detect errors and problems. However, the monitoring system reacts only when there is serious damage and, unfortunately, when it is too late to protect the data. Statistically, most disk failures are due to improper transportation of the laptop. Frequent carrying of equipment during work or carrying a laptop in a bag leads to a significant number of shocks and, as a result, mechanical damage. However, damage can also be electronic (disk sector wear).
You can Diagnose a Failed Hard Drive by:
- By the characteristic noise, trembling, and tapping (in the event of a breakdown, the sound may become louder).
- The lack of sound of a disk.
- By checking the BIOS for operability (if the disk is faulty, then the BIOS will not be able to identify the device).
Note! Hard drive repair and data recovery is quite an expensive service. Therefore, the best solution would be to purchase a new drive or SSD.
Failure of the Matrix or Video Card:
Listen carefully to the sounds coming from the laptop. If you can hear the drive and cooler startup, and the lights are on to confirm that the device is on, the possible cause is a faulty video card. In this case, you should try connecting an external monitor to the VGA or HDMI connector. If an image appears on the additional screen, this means that the video card is working and then its replacement, respectively, will not be required.
Then check the operating system settings on the second monitor. If everything is in order in the device manager, then you should try moving the laptop lid. If the image is restored for a while, then the contacts in the laptop case that connect the matrix to the rest of the device components may have been damaged. Another reason is the malfunction of the matrix itself. In this case, unfortunately, it is only possible to replace the screen with a new one.
If the image did not appear on the second screen, then with a high degree of probability the video card is out of order. In this case, you will need to replace the entire motherboard, since video cards in laptops are often soldered.
Diagnosing damage to a laptop motherboard at home is quite difficult. Here are the common symptoms of a breakdown:
- The laptop does not turn on, a squeal is heard, and the LEDs flash.
- The appearance of the “blue screen of death”
- The laptop turns off randomly
- Problems with video display
- Notebook components do not work
- There is no image on the display
- Constant freezes or freezes
- USB ports not working
- The BIOS cannot identify the device
- The laptop just won’t turn on
A power supply failure is a common cause of motherboard failure. Unstable power and power surges can also easily damage the laptop component. Overheating or contact with liquid can also damage the motherboard. The accumulation of large amounts of dust, combined with other problems, can also damage the equipment.
Note! In addition, failure is sometimes caused by manufacturing defects. They can be expressed, for example, in the presence of defective electrolytic capacitors.
In some situations, the motherboard may be damaged beyond repair. And in certain cases, the repair will simply become an unprofitable service due to the high cost (when it is cheaper to buy a new item).
Diagnosis and Elimination of Software Errors:
Crashes, software bugs, and virus attacks can all cause your laptop to stop working. However, these types of problems do not at all indicate that the device is no longer suitable for use. Proper diagnosis and troubleshooting of the problem will not only restore the operation of the laptop but will also save all the data and files that are located on the disk.
Boot in Safe Mode:
Safe Mode is a special Windows boot option that starts the OS with limited functionality, using only basic elements. This mode helps to diagnose malfunctions that affect the start of the system. At the same time, it is able to prevent even more damage to the OS by minimizing the functionality mentioned above.
Start Safe Mode like This:
- Turn on your laptop. While logging in, press and hold the left SHIFT key and simultaneously hold down the power button.
- After the reboot, a special window will open, in it click on the “Troubleshoot” tab.
- Next, select “Advanced Options”.
- From the list of available options, click Download Options.
- The system will ask you to restart in order to enable safe mode.
- Finally, click on the 4 key to enter Windows Safe Mode.
If everything goes well, then following the steps above will help you launch Windows 10 Safe Mode or another version of the OS. Through it, it is permissible to diagnose many sources of problems, whether it is a problematic driver or another software component.
Diagnosis and Elimination of Software Errors:
1. Using the Recovery Drive
The laptop may not turn on due to Windows errors. To fix them, it is perfectly acceptable to use the recovery disk (if available). This is done as follows:
- Insert the OS recovery disc (CD/DVD or USB stick) into the laptop.
- Reboot it and press a certain key (F1, F2, F12, DEL) at the beginning of the boot process in order to enter the BIOS. At the same time, remember that each laptop or desktop PC has its own key for entering the BIOS (that is, they are different).
- Once in the BIOS or UEFI menu, look for the “Boot” option.
- As a priority drive, select the inserted media (DVD or flash drive).
- To save your settings, click Save Changes and Exit before exiting.
- After another restart of the laptop, the recovery disk menu will open. Click on the “Diagnostics” option, then – “Repair your computer”.
- After that, the OS recovery process will begin, which will take some time.
Once Windows is ready, the laptop will restart. If the recovery disk menu then opens again, change the startup priority in BIOS or UEFI to a standard hard drive or SSD.
2. Bios Problems:
Errors in the BIOS or UEFI can also be the answer to the question of why the laptop does not turn on. Because of this problem, the OS will probably be blocked from loading. The way to access the BIOS/UEFI will depend on the motherboard. In most cases, when you start the OS, you just need to press the F2, F10, and F12 or Delete key. The user will then access the BIOS screen in “Easy Mode”.
The first step is to try restoring the default settings. This is done as follows:
- Follow the instructions above to enter the BIOS.
- After gaining access to the BIOS, use the keyboard keys (right arrow) to navigate to the “Exit” tab.
- Then select and activate the “load setup defaults” option.
- Confirm the changes and then click F10 to save the settings and exit the BIOS.
- The laptop will then restart.
Also, the boot problem can be fixed by changing the BIOS settings. However, be careful with these manipulations, as the consequences can cause more serious problems with the laptop. Therefore, without proper knowledge, you should not edit the BIOS parameters. In this case, you should simply use the restore default settings.
3. Graphics Driver Failure:
The video card driver can cause a number of malfunctions in the laptop. Some problems cause only minor problems and some completely disrupt the functionality of the equipment. However, getting rid of this “trouble” is quite simple.
You can fix the driver even if the OS does not start. But for this, you need to turn on Windows in safe mode (how to do this is indicated above). Next, you need to follow the instructions, depending on the option of the chosen solution to the problem.
Solution 1: Roll Back the Driver
The first way is to roll back the driver to an older version or reinstall it. To do this, do the following:
- Click Win + X, then select “Device Manager”
- Go to the “Display Adapters” section.
- Double-click on your video card with the left mouse button.
- Go to “Driver”.
- Try rolling back or updating the driver.
If the problem is not resolved after this, move on to another step.
Solution 2: Disable Browser Extensions
Many users have reported that certain browser extensions cause the driver to crash when watching YouTube videos. Thus, if a malfunction occurs, you can try to remove problematic extensions, which sometimes helps to solve the problem completely. This is done as follows:
- In the browser, in the upper right corner, click on the menu icon.
- Go to “More Tools” or “Settings”.
- There, find the parameter responsible for installed extensions.
- A list will open, disable problematic extensions in it and restart the OS. It is also advisable to reinstall the video card driver.
Solution 3: Uninstall Lucid Virtu MVP
If the problem is not resolved by applying the two methods described above, then you should try to uninstall Lucid Virtu MVP. This utility is automatically installed on computers that have Windows version 8.1 – 10.
Solution 4: Clean Your Laptop Cooling System
Sometimes, due to excessive dusting of the video card fan, the driver starts to freeze, so you should try to clean the laptop cooling system from dust. To do this, open the case, disconnect, and then pull out the cooler and thoroughly clean it of dust. Also, do not forget about cleaning the ventilation grille, because it is through it that hot air is blown out.
4. OS Bootloader Issues
If you experience a problem starting Windows 10, the cause may be a faulty OS loader. In this case, you can solve the problem as follows:
- First, you need to have an installation version of Windows 10 on a disk or flash drive, with which you should turn on the laptop. After starting, you need to select “Advanced options”, and then enable the command line (CMD).
- After its launch, you need to sequentially enter commands and fix the actions by pressing ENTER.
- First, you need to start Diskpart with the “DISKPART” command, and then you should enter the “LIST VOL” command, which will display a list of volumes. Then you need to find a FAT32 file system volume ranging in size from 99 MB to 400 MB.
- First, select this volume with “SEL VOL 2” and then “ASSIGN”. At the same time, give it the first free letter as a name. At this stage, you need to remember the letter you just assigned and the one that is marked with the Windows partition (these are “I” and “C”, respectively).
- Next, enter the command “SEL VOL 2” (that is, select the volume just marked).
- Then you need to format it by pressing “FORMAT FS=FAT32”
- Now you can close Diskpart with the “EXIT” command.
- Next, in an open command prompt, type: BCDBOOT C: / WINDOWS / SI: / F ALL (where C is the drive with Windows files, I is the letter assigned to the hidden partition).
- Before finishing the steps, it is worth removing the previously provided letter from the EFI partition. That is, you need to restart Diskpart and enter: “LIST VOL” “SEL VOL 2” and “REMOVE LETTER=I”.
- Type “EXIT”, remove the Windows 10 installation media and start the laptop.
It is important to note that all these actions should be performed only by experienced users. If there is no understanding of what is being discussed above, it is better to give the laptop for repair to a service.
5. Reinstalling Windows
If all of the above methods did not have any effect, then it’s time to reinstall Windows.
- Prepare a flash drive with files for installing Windows.
- Reboot your laptop. In BIOS, specify the connected flash drive as the priority device for starting the OS.
- Restart your laptop.
- When enabled, the Windows Installer will open. Just follow the instructions in it. Installing a modern OS does not require professional skills.
If the laptop does not turn on at all after certain actions or circumstances, the laptop may stop turning on at all. This can happen both through the fault of the user himself and due to various third-party reasons. Next, let’s look at common problems.
- Due to the compactness of the laptop, all the equipment inside the case is located as close to each other as possible, and, moreover, it has a complex architecture system. Due to inattention or negligence when cleaning, it may well.
- You with a high degree of probability could incorrectly connect the connectors to the motherboard, for example, matrix or battery (or even forgot to do it).
- While cleaning, you may have accidentally hit or scratched the equipment. In this way, serious damage to the spare part can be caused.
- Water, alcohol, or other liquid may have come into contact with the boards.
- Individual elements may have been damaged by static electricity.
To Try to Solve the Problem, Use the Following Tips:
- Disconnect the CMOS battery from the motherboard and hold down the power button for 7-10 seconds.
- Remove the battery and reconnect it after 15-20 minutes.
- Look, If thermal paste was applied, check if the excess has leaked onto the hardware. So, then gently wipe off the residue.
- See if the BIOS diodes are on or flashing during startup, it is necessary to decode the signal and find out the exact cause of the malfunction.
- If none of the above helped, you should take the laptop to the service in order to be examined by an experienced specialist.
If the laptop does not turn on after overheating, it is worth waiting 20-30 minutes during which it will cool down. However, the consequences can be really serious, and then simply waiting will no longer help.
At best, there will be a decrease in the performance and heating of the case. More unpleasant is the situation when an overheated laptop will turn off spontaneously.
Note! Too hot hardware also causes system errors such as graphics issues, freezes, or unexpected reboots.
Among the most serious consequences of overheating is damage to the video card, processor, or motherboard. Some elements may even melt. After that, the equipment will completely fail, and the only solution is to replace them with new ones.
If you managed to avoid damage to parts, and the laptop turned on after cooling, it is important to do the following:
The first action should be to make sure the cooling system is working efficiently. It is enough just not to put the case against the wall (blocking the ventilation holes), and then the airflow will begin to circulate freely. It’s a good idea to purchase a cooling pad. It is equipped with fans that provide additional airflow and maintain the optimal temperature of the laptop components.
The ventilation holes may become clogged with dust. Therefore, the laptop must be cleaned regularly. You also need to change the thermal paste about every 2 years. It helps to more efficiently transfer heat from the processor and video card to the heatsinks.
After Software Update:
The software, in rare cases, can also disable performance. If, after updating the software or OS, the laptop stops turning on, you should start Windows in safe mode and remove the problematic software or roll back the OS version.
If the laptop does not turn on at all
Spontaneous Laptop Shutdowns: Causes and Methods for Their Elimination
There are several reasons for shutting down a laptop on its own. This might be a problem:
- System settings
- The presence of viruses
- The presence of a fault or damage
Under certain settings, the laptop may go to sleep because it has not been used for a certain period of time, which is especially true when it is running on battery power. It may also happen that the manufacturer, in order to increase battery life, set a parameter at which the OS goes into sleep mode even after 10 minutes. You can change this yourself in the “Power Options” section.
