How to Fix a Laptop that Won’t Turn On

A PC or laptop that won’t turn on can be a traumatic experience, especially if you rely on it as your primary device.

However, it’s important to take a deep breath and consider what the potential causes might be. If it’s one of the six below, we’ve included information on how to hopefully get up and running again.

Method 1. Check the power supply


This is one of the most common problems. There are many things that can go wrong, from using the wrong laptop power supply (wrong voltage distribution) to a blown fuse in the plug.

So check that the adapter is indeed the right adapter for your laptop and is providing the right voltage and amperage. A sticker or label on both the power supply and the laptop will confirm this. Some third-party chargers also emit power at a rate that is only comparable to what your device requires to run. In particular, older devices can lose significant battery life while in sleep mode and may therefore not turn on if one of these chargers is used.

Many laptops – especially from the same manufacturer – use the same plug size, and if you own multiple, it shouldn’t be too hard to mis-plug the power supply, which may or may not provide a different voltage. enough current.

If it is the correct charger, next check the fuse in the plug. Use a screwdriver to remove the fuse and exchange it for one that is known to be good. If you have a spare power cable that will plug into the mains, this is a much faster way to check that it’s not a fuse fault.

Check the wires themselves, as the power supply fails, especially if you carry them around. The weak point is at the ends where it connects to the black brick block and at the end where it connects to the laptop. If you can see colored wires inside the black outer shield, it may be time to buy a new power supply unit (PSU).

The PC power supply can also be problematic. It’s unlikely you’ll have spare parts to install and test, so check the fuse in the plug first. There’s also a fuse inside the PSU, but it will require you to take it out of your PC (by no means feat) and then remove the metal case to check if that’s the problem.

One of the most common PC power supply problems is that the PC will shut down unexpectedly rather than fail to start.

If the LED comes on indicating that power is coming, make sure that the power button in your computer case is connected and working properly.

You can short the appropriate motherboard pins together (check which ones in your motherboard manual) to remove the power button from the equation. Some motherboards even have a built-in power button.

Method 2. Check the screen


Try disconnecting any external displays including projectors and monitors to make sure they don’t prevent your laptop from booting into Windows.

If your computer’s power LED lights up and you can hear the hard disk(s) or the fan whirring but there’s no picture on the screen, darken the room and check to make sure there’s no problem. The picture is too blurry on the screen.

It’s easy to think that a laptop won’t boot when, in fact, it’s the screen that’s the problem.

If there is a blurry image – possibly the Windows login screen – then the inverter may have failed, but this only applies to older laptops before LED backlighting.

Replacing an inverter is difficult and it is important that you purchase the right replacement parts. Since inverters aren’t exactly cheap, you can’t buy the wrong one. It’s best for professionals, but since your laptop may be old, it might be time to buy a new one.

If your laptop seems to start up fine, but there’s no picture at all, it’s possible that the LCD panel is faulty. Replacing a laptop screen is possible, but difficult, and screens can also be expensive.


There’s not much you can do to fix a broken PC screen, but it’s easy – or easier – to swap out the power and video cables, or even the entire display to see if that’s the reason why your PC isn’t working. you can’t start or not.

Method 3. Unplug and portable USB drive or memory card

Assuming everything is fine with the power supply and monitor, your computer may be stuck before loading Windows.

The classic culprit here is a USB drive or memory stick plugged into a USB port or card reader. Usually, you will see an error message like “Operating system not found” which can lead to unnecessary panic.

Most of the time, that means the BIOS is set up to try to boot from removable storage drives (including cards) before the internal hard drive.

It could also be a disc left in the DVD or Blu-ray drive, so check them out.

Method 4. Try the Rescue Disk

If none of the above works, you can try booting from a rescue disk or USB drive.

If you have, a Windows DVD can be used, but if not, you can download (using another computer – obviously) the rescue disc image and burn it to a CD or DVD or extract it to the drive USB flash. Then you can boot from there and try to fix the problem with Windows.

If a virus is causing the problem, use a rescue disc from your antivirus service provider as it will include scanning tools that can find and remove malware.

Method 5. Boot into Safe Mode

Even if you can’t boot into Windows, you can still enter safe mode. Press F8 while your laptop is booting and you’ll get a menu offering to boot into Safe Mode. Here’s how to enter safe mode. However, that won’t work in Windows 10, as you need to be in Windows before you can go into safe mode. In that case you will need to boot from a rescue disk or drive as described above.

If you can get into safe mode, you can undo any changes that cause your laptop or PC to stop booting. You can try uninstalling any new programs you recently installed, uninstalling recently updated drivers, or creating a new user account if the account is corrupted.

Here are more detailed instructions on how to fix a corrupted user profile.

If you see an option to repair your computer, try that.

Method 6. Check for Faulty or Incompatible Hardware

If you have just installed some new memory or another piece of hardware, it may prevent your computer from starting. Delete it (reinstall old storage if necessary) and try again.

If your motherboard has an LED that shows the POST code, search your manual or online to find out what the display code means.

Usually, it can be very difficult to start a newly built PC. The best tip here is to unmount everything but the bare minimum needed to boot into BIOS:

  • Motherboard
  • CPU (with heatsink)
  • Graphics card (if there is a graphics output on the motherboard, remove any additional graphics cards)
  • One memory stick (remove any others and leave the only stick in slot 0 or depending on the manual)
  • Power supply
  • Screen

All other hardware is unnecessary: ​​you don’t need a hard drive, optical drive, or any other component for your PC to start.

Common reasons why a newly built PC won’t boot are:

  • The power lead is not properly attached to the motherboard. If your board has an extra 12v socket near the CPU, make sure to attach the correct lead from the power supply outside large 24-pin ATX connector.
  • Components are not installed or positioned correctly. Remove the memory, graphics card and CPU and re-insert it, check for any bent pins on the CPU and CPU socket.
  • The power button wires are connected to the wrong pins on the motherboard.
  • The power cable is not attached to the graphics card. Make sure the PCI-E power leads are connected correctly if required by your GPU.
  • The hard drive is connected to the wrong SATA port. Make sure the main drive is attached to the SATA port controlled by the motherboard chipset and not a separate controller.

Sometimes the reason why a PC won’t boot is due to a faulty component and there’s no easy fix. Hard drives are a common problem. If you can hear occasional rattling or the drive spins up and shuts down continuously, those are signs that it has failed.

Sometimes people find out that removing the drive and putting it in the freezer for a few hours (in a freezer bag) does the trick.

However, this is usually a temporary fix, and you should have a second drive on hand to quickly back up or copy any files off the drive that you need.

If you can’t get the drive working again, it’s time to start fresh with a new hard drive. In fact, you’re better off buying an SSD. Hopefully you have a recent backup of all your important files!
