Here is why your computer won’t boot up and What you can do to fix it. If, on a beautiful day, your laptop won’t boot, don’t rush to the computer repair centre right away, but try some of the following simple laptop handling steps.
Maybe with just a few small checks below, you can immediately fix the problem of the computer not starting without spending a dime.
On Windows 7, Windows 8/8.1, and Windows 10, these techniques can be used to resolve the issue of the computer not starting.
There are many causes of computer failure to start. I’m also facing this error.
How to fix a Computer that won’t start?
- Check the power-charging cord.
- Check the screen
- Take the USB or memory card out of the device.
- Use the rescue disk
- Start the device in Safe mode
- Disconnect from the docking station
- Remove and re-insert the battery
- Discharge the energy in the computer
Check Power – Charging Cord
This is the most frequent case when the laptop does not start; the cause may be a loose connector, an incorrect charger, a power line problem, or a broken laptop charger.
Test Steps:
- Try another electrical item plugged into this outlet or put the charger into a different outlet in the house to test the power.
- Check the charger: please check whether the charging cord you are using is the standard charger of the laptop or not. Many chargers can fit different laptops, but if their voltage is insufficient or unsuitable, it can also cause the above phenomenon.
- In addition, it is also possible to charge a damaged battery because you carry it around too many places. Look closely at the entire charging cord; if the line is open and exposes the sub wires, it’s time for your laptop to need a new charger.
Many things can go wrong, from using the wrong laptop power supply (leading to incorrect voltage transmission) to a blown a fuse in the plug.
So, check if the adapter (charger) is suitable for your laptop, provides average power, and has the correct amperage.
Labels or symbols on both the charger and the computer will confirm this. Some third-party chargers are very slow.
Older devices can lose significant battery life while in Sleep mode and may fail to power on if one of these chargers is used.
Many laptops use the same plug size, and if you own multiple plugs, there’s a good chance you’re using a different voltage or not providing enough power.
If the charger is correct, check the plug’s fuse. Use a screwdriver to remove the fuse and replace it with a new one.
If you have a spare power cable, this is a much faster way to check if the problem is with the charger or the line
Recheck the charging cord because it is easy to break if you often carry it around. The points to note are the connection to the charger and the link to the laptop. If you can see the wire inside the black outer protective layer, it might be time to buy a new charger (PSU).
Check the screen
If you start the computer and don’t see the screen but still hear the sound of the hard drive or the cooling fan, the problem may be in the net.
Try bringing the laptop into a dark place and see if the screen has any bright spots or images (very faint, you need to look closely to see).
The monitor’s high voltage is most likely damaged if the image is still visible on the screen. A laptop’s high voltage (inverter) is responsible for turning the DC of the battery or charger into the alternating current to supply the screen. Replacing the high voltage is not too complicated if you have a screwdriver.
Still, it is essential that you buy the correct type of high voltage suitable for the laptop, and because its price is relatively high, you need to be sure. Yes, if you don’t mind losing money unfairly.
Another scenario is when the laptop turns on, but no image shows up on the screen; in this situation, the LCD screen is probably broken.
Like high voltage, you can manually replace it. Still, if your laptop has been used for a long time, you should consider buying another replacement because the cost of purchasing a new screen often equals the value of this laptop sold.
Take the USB or memory card out of the device.
Suppose you have checked the above two objects and still do not solve the problem. In that case, the Windows startup process may be interrupted because a USB or memory card with the Windows installer is still plugged in, and the computer is trying to boot from these devices. Then you must take the USB or memory card out and restart the computer.
Use the rescue disk
The computer may not start because the virus has “eaten” system components. There are two ways to deal with this problem: reinstall or fix the error with a rescue disk such as Hiren’s Boot CD, WinBuilder, Bart’s PE Builder, or mini PC. Suppose the first method loses all numbers software and old settings on the machine.
In that case, the second way can bring the system to a stable state after scanning for viruses in DOS or PE (Preinstalled Environment) and restoring system components damaged by viruses.
Start the device in Safe mode.
Safe mode starts Windows in its ground state, using a limited set of files and drivers. The default settings and underlying device drivers are not to blame if the issue does not appear in Safe Mode. You can determine the problem’s origin and help fix several PC issues by watching Windows in Safe Mode.
The safe mode comes in two flavors: standard Safe Mode and Safe Mode with Networking. You may access the Internet and other computers on your network using Safe Mode with Networking, which adds the network drivers and services you require.
A dark or blank screen, the login screen, or the Settings menu are all ways to start your computer in Safe Mode.
Safe mode may be used to access Windows even if the computer cannot boot normally. After the boot process, press F8; choose Safe Mode from the menu that displays.
The laptop not booting may be due to a conflict between software or drivers. So after entering Safe Mode, please remove the newly installed programs or updated drivers one by one and restart the computer.
Luckily, the machine will typically boot without removing the programs and drivers. See the article How to start Windows 10 in Safe Mode for additional details.
Note:
While in Safe Mode, your screen resolution may drop slightly, specific applications may not work correctly, or your computer may run slower than usual. This is completely normal because it is just the effect of some drivers not running.
After solving your problem, you need to exit Safe Mode to test and see if this works. To do this, restart the computer. On reboot, Windows will start in normal operating mode.
If you boot in Safe Mode and your computer continues to crash, there may be something wrong with the hardware. You might need to bring the appliance to a maintenance specialist for more help.
How to fix computer powers on but shows an error message.
If the computer powers on but shows a black screen that says “no boot device” or “disk error,” the computer cannot boot from the hard drive where Windows is installed.
Check the boot order settings in BIOS or UEFI, and ensure the boot from the correct hard disk is configured.
The hard disk isn’t correct and can’t be booted any longer if it doesn’t appear in the list.
If everything is fine in the BIOS, you may have to insert a Windows installation disc or recovery disc to run Startup Repair.
This will help Windows restart. You do not need to try to run the fixmbr or fixboot commands because Startup Repair will automatically run them for you.
If some data has overwritten the drive’s boot sector, Startup Repair will repair the boot sector. You may have a hardware problem if the recovery tool doesn’t load or can’t be found on the drive. Check the BIOS or UEFI boot order if the recovery tool is not loaded.
How to fix computer power on but Show blue error screen.
If Windows crashes or this blue screen every time it starts, you may have a hardware or software problem. For example, malware or faulty drivers may be loading at startup and causing problems, or your computer’s hardware may be damaged somewhere.
The reason lies in the hardware.
An incompatible stick of RAM can also be the cause of the laptop not booting. If you just replaced a new RAM stick and can’t start the machine, remove it and return the old RAM stick to the computer.
If the problem is fixed, congratulations, but you must buy another RAM stick if you still intend to upgrade your computer’s RAM.
And if the problem is not in the RAM, the hard drive may be the “culprit.” Please put your ear to the machine to see if the hard drive is working, or if it works, is the noise “quiet”? A very recognizable sign of a hard drive problem is that it keeps making strange and regular noises.
At this point, replacing the new hard drive is something to think about, but what about the amount of data accumulated in the old hard drive for a long time?
Before you rush to bring it out to expensive data rescue services, you can try the method that people in the industry have heard about each other: put it in the freezer for a few hours (of course, it must be wrapped carefully to protect it from damage avoid moisture), then take it out, reinstall it and restart the machine.
If it works again, don’t be too happy, it may only “recover” temporarily and continue to fail on the next boot, so move all necessary data to a safe place and be prepared. You should buy a new hard drive because sooner or later you will need it.
Separate device from the docking station.
To be sure, unplug your laptop from the docking station (the device that joins peripherals, such as laptop power adapters), then try turning it on again. Make sure the docking station is not the cause of the problem.
Remove and re-insert the battery.
Note:
Many new laptops (especially MacBooks) do not have removable batteries.
The laptop may also be in a state that prevents it from booting correctly. Try unplugging the computer’s power cable first, then taking out the battery.
Leave the battery and the power cable disconnected from the laptop for at least a minute. After about a minute, re-insert the battery in the laptop, connect the power cable, and try turning your computer back on.
Even though every laptop is unique, removing the battery is somewhat similar. However, all new MacBooks from Apple use a built-in battery, and users usually cannot remove it themselves.
Whether your laptop is running Linux or Windows, the steps below will show you how to remove the battery. When changing a laptop battery, you should remove the old battery before installing the new one.
Note:
Many ultrabook laptops have external non-removable batteries. Removing this model’s battery will require a technician’s help and must open the case of the computer.
How to remove the laptop battery
- If your laptop is connected in, unplug the power cable or the charger.
- Turn the laptop upside down.
- Find the battery latch on the bottom of the computer. The image below shows some standard battery latches commonly found on laptops.
- Slide the latch switch to the other side and hold it until the battery is freed to remove it.
- On some laptops, the battery will turn on by itself. In other models, you will need to pull the battery out gently.
Other situations
Although most laptops have only one latch, some models require two latches to be slid to remove the battery.
On these laptops, the latches still look like the example above but need you to move both latches simultaneously, often in opposite directions.
Finally, some older laptops (IBM laptops) require pulling the latch out and then pushing it towards the battery.
Can’t find the pin latch?
Suppose you can’t find any battery latch or button to remove the battery on the bottom of the laptop.
In that case, your computer may have a different mechanism for removing the battery. You can bring it to the service and repair centers for help if necessary.
You should also refer to the documentation that came with your laptop or check the manufacturer’s website for battery removal steps for your particular model.
Discharge the power in the computer
Sometimes a small amount of remaining power can prevent your laptop from turning on. You can picture it as an “obstructed current.” By performing the following steps, you should discharge any excess power from your laptop and try turning it on again.
- Remove the battery and unplug the AC adapter (PC charger).
- The power button must be depressed for at least fifteen seconds.
- Without re-inserting the battery, plug the AC adapter back into the laptop.
- The laptop may be started by pressing the power button.
Note:
If this doesn’t work for you, repeat the process above, but in step two, hold the power button for a minute or so.
How can data be recovered if the Machine Won’t Boot Up?
You can utilize the Windows installation disc or Linux live CD to restore essential files that will be lost and wish to back up before reinstalling Windows. You may copy data to an external hard drive or USB stick using these programs, powered by CDs, DVDs, or USB drives.
If you can’t boot the Windows installer or Linux live CD, you may need to enter the BIOS or UEFI to change the boot order.
If even this doesn’t work, or you can boot from the above devices, but the computer freezes and can’t access the hard drive, then there’s a good chance that some hardware is damaged.
To back up the necessary data, you could try removing the computer’s hard disk and installing it on another machine.
Final Thought
Windows 10 won’t boot? Don’t despair if your computer won’t start. There’s a massive number of fixes out there. The trick is knowing which tools to use first.
Our advice is to start with the most straightforward holes and, in order, move to the harder ones. Above I have suggested ways to fix errors if your computer suddenly won’t start.
With the methods I mentioned above, you can quickly select them. I am sure the experience I share with you will be appropriate.
