If your computer won’t turn on after power outage, don’t panic! There are a few things you can do to try and fix the issue.
One day while working on your PC, it might happen that suddenly the power supply to your system is disrupted. A power outage will usually cause your computer to go off without warning, and you may find that when the power comes back on, your PC won’t turn on or boot up again.
This might be a bit worrying, especially if you have important work to do or data that needs to be saved. But don’t worry just yet – it’s likely that you can fix the problem if you take a few steps.
In this blog post, we will discuss some of the most common causes of this problem and how to troubleshoot them. We will also provide some tips on how to prevent your computer from not turning on after a power outage in the future.
Why Won’t the Computer Turn On After Power Outage?
There are a few possible reasons why your computer won’t turn on after a power outage.
- Damaged PSU: The first and most common reason is that the power supply unit (PSU) has been damaged or corrupted due to the sudden power surge.
- Faulty Hardware: Another possible cause is that one or more of your computer’s components, such as the motherboard, CPU, RAM, GPU, storage drive, etc., have been damaged due to the power surge.
- Corrupted Boot Data: Yet another cause is that your boot data could have become corrupted due to the power outage and needs to be restored or replaced.
- Damaged CMOS battery: The CMOS battery, which stores your BIOS settings, could have been damaged due to the power surge.
Fix: Computer Won’t Turn On After Power Outage
Now that you know the possible causes of this issue, it’s time to take action and fix your computer.
Fix 1: Check the PSU
The first step is to check if the power supply unit (PSU) has been damaged due to the power surge. The PSU is the component that supplies electricity to your computer, so if it’s damaged, your PC won’t turn on.
To check if the PSU is working properly, disconnect all cables and power cords from the back of the CPU and then press the power button. If nothing happens, then it’s likely that the PSU is either damaged or faulty. Other than that, you can also check the power cord and make sure that it’s properly connected.
Fix 2: Check if the Fans Are Working
If the PSU is not damaged, then you should check if the fans inside your computer are spinning. This will help you identify whether there is an issue with the power supply or another component. CPU fans, case fans, and GPU fans are all important components that need to be checked.
If none of the fans are spinning, then it’s likely that the power supply is faulty and needs to be replaced. There is a likelihood when Computer will not turn on but Fans are running but that’s an different issue.
Fix 3: Check for Faulty Components
If the fans are working fine, it means that the computer is receiving power. It’s time to check if any of your computer’s components have been damaged due to the power surge. To do this, you’ll need to open up your system and visually inspect each component for any visible signs of damage.
If you find a faulty component, you’ll need to replace it with a new one. You can buy replacement components online or from a local computer store.
Fix 4: Perform a POST Test
If the damage is not visible to the naked eye, you should perform a POST (Power On Self Test) test to check if all the components are working properly. To do this, you’ll need to press the power button and watch for any error codes that appear on your monitor. These will help you identify which component is causing the issue.
Once you’ve identified the faulty component, you can replace it with a new one or get it repaired. After you’ve replaced the faulty components and performed the POST test, your computer should be able to boot up properly. It’s important to remember that if your PC still won’t turn on after following these steps, it could be due to an issue with the motherboard or CPU.
Fix 5: Restore or Replace the Boot Data
If all of your components are in good condition, then it’s likely that the problem is with your boot data. This can be easily fixed by restoring or replacing the boot data.
You can use a Windows recovery drive to restore your system’s boot data. You can also try using another computer to copy the necessary files onto a USB drive and then move them over to your PC.
Fix 6: Check if the Hard Drive Is Working
Next, you should check if your hard drive is working. To do this, you’ll need to open the system and visually inspect it for any visible signs of damage. If you find any, then it’s likely that the hard drive is damaged and needs to be replaced.
To check if the hard disk is damaged, remove it from your current system and place it on another one. If the drive is detected, then it means that the drive is working. If it doesn’t, then the hard disk is impaired, and that’s why the computer is not turning on. In that case, you need to get the hard disk repaired or replaced.
Fix 7: Replace the CMOS Battery
Finally, you should check if the CMOS battery has been damaged due to the power surge. The CMOS battery stores your BIOS settings and needs to be replaced if it’s not functioning properly. To replace the CMOS battery, you’ll need to open up your computer and locate the battery.
Note: If you are not tech-savvy or amateur with computers, it is recommended to take the help of experts as the following steps are too technical, and even a minor mistake can be fatal for your computer.
Here is how to do that:
- Remove the power cables and other external peripherals from your CPU.
- Now, open the side panel of your CPU by unscrewing the screws.
- After opening the side panel, look for the CMOS battery slot on your PC’s motherboard.
- In our case, it is below the GPU slot. So we need to temporarily remove the GPU first to replace the CMOS battery.
- You can easily detach the GPU from the motherboard using the screwdriver.
- Disconnect the power cable of the GPU and carefully detach it from the slot.
- Now you can remove the CMOS battery from its slot. Simply push the switch holding it with your finger or a pointed object.
- The battery will be popped up so you can pick it up easily.
- Now insert the new battery in the empty slot and push it inside.
- The battery will be attached.
- Now attach the GPU and close the side panel of the CPU.
Fix 8: Contact the Computer’s Manufacturer
If all of the above steps don’t work, then you should contact your computer’s manufacturer for assistance. They can help diagnose and repair any hardware issues that may be causing the problem. You can visit the official service center or the nearby computer repair center for help. Taking help from an expert will let you find the root cause of the issue quickly and accurately.
How to Avoid Such an Issue in the Future
In order to avoid such an issue in the future, it’s important to ensure that your computer is adequately protected against power surges. Here are a few preventive tips:
- Invest in a surge protector to protect your computer and its components against power spikes.
- Unplug your computer from the wall socket when not in use.
- Install a reliable UPS (Uninterruptible Power Supply) for additional protection.
- Make sure to keep your computer in a well-ventilated area and away from any heat sources.
- Regularly maintain your computer and its components to ensure they are in top condition.
- Keep a backup of all important data so that you can recover it easily in case of an emergency.
A power surge can be a major hurdle for your computer, but if you follow the above steps and take preventive measures, you can mitigate any damage to your system. Ultimately, it’s important to be prepared for any sort of eventuality and have the right tools on hand in order to get your computer up and running as quickly as possible.
With the right strategy, you can protect your PC from a power surge and save yourself time and money. It’s important to remember that if none of these solutions work, then you should contact an expert for help.
