We’ve all been there – you open your laptop and press the power button, only for nothing to happen. Don’t panic! It could be a problem with your Dell laptop not turning on, which is, unfortunately, very common.
Thankfully, the good news is that it’s usually an easy fix that can be made without having to take technical measures or visit a repair shop.
In this blog post, we will go through some potential causes as well as how to troubleshoot them in order to get your Dell laptop up and running again.
Why My Dell Laptop Won’t Turn On?
There are a few possible reasons why your Dell laptop won’t turn on. These include:
- Battery Issues: If the battery is dead or not properly connected, then your laptop will not be able to power up.
- Defective Electrical Outlet: Your laptop may not be receiving enough power from its AC adapter or the outlet it is plugged into.
- Overheating: If your laptop has been on for a while, it may have overheated and shut down to prevent any permanent damage.
- Faulty Internal Components: There could be something wrong with one of the internal components, such as the RAM, hard drive, or motherboard, that is preventing the laptop from starting up.
- Firmware: If the firmware of your laptop is corrupt, it may prevent the system from booting.
Note: If you see flashing lights or hear beeping noises when attempting to power your laptop on, this could be an indication that there is a hardware issue. The type of light or sound can also provide clues as to what the problem might be. Consult your laptop’s manual for information about what different lights and sounds mean.

Troubleshooting Tips for When Your Dell Laptop Won’t Turn ON
No matter whether you’ve experienced working on computers or are absolutely clueless about tech, you’ll find something useful here to help you identify and solve the issue of a Dell laptop not booting up correctly.
Disclaimer: Be aware that opening up your laptop may void its warranty, so proceed with caution and at your own risk. It is recommended to take professional help if you are not sure about what to do. The writer of this article will not be responsible for any damages caused due to following the instructions mentioned in this article.
Fix 1: Ensure the Battery is Working
The laptop battery is the number one cause of laptops not turning on. The first thing you should check is that the battery is properly connected and in working condition. Most Dell laptops come with a removable battery; take it out and then put it back in again to ensure that it is properly connected.
To see if the battery is causing your problems, simply follow these easy steps:

- Remove the battery from your laptop socket.
- Plug the laptop directly into the power supply using the charger.
- Check if the laptop is turned on.
- If that is the case, the problem is with the battery.
Fix 2: Factory Reset Your Laptop
If you can’t get your laptop to turn on and the battery is working, then you may need to perform a hard reset. A hard reset is a process of reverting a device back to its factory settings.
It essentially restores the laptop to its original state when it was first purchased and removes all of the user-installed programs and changes that have been made to the device since then. This means that any software, data, settings, or preferences will be lost during the process.
To Hard Reset your laptop, simply follow these easy steps:
- Power off your laptop and carefully remove the battery.
- Remove all of the external hardware components and disconnect the laptop charger.
- Now press and hold down the power button for about 15-30 seconds to completely drain out any electricity (residual electric charge) inside the laptop.
- Insert the battery in the laptop and reconnect the charger. DO NOT connect any external peripherals right now.
- Press the power button to turn your laptop on.
- The laptop will be turned on, and you will see the manufacturer’s logo (In our case, Dell).
- Finally, you will get the option to Start Windows Normally.
Note: If your laptop has a non-removable battery, then also you can follow the above steps, except you don’t have to remove the battery by any means. However, since the battery is un-detachable, it might take a longer time to drain the power of the laptop.
Fix 3: Refresh System BIOS
Sometimes, the laptop will not turn on because of a corrupted system BIOS. The BIOS is the set of instructions that manage your laptop’s hardware and software settings, and it can become corrupt if a virus has infiltrated your computer or if you have recently done some major updates to your operating system.
To reset BIOS settings, you will need to open up your laptop and locate the CMOS battery. Disconnect this battery for a few minutes and reconnect it again. This should clear all of your stored settings and get your laptop working again.
Fix 4: Change CMOS Battery

CMOS (Complementary Metal-Oxide Semiconductor) is a type of memory that stores configuration settings, such as BIOS settings and time/date information. If the CMOS battery is not working correctly, it can cause your Dell laptop to not turn on.
If you want to change the CMOS battery on your own, here are the steps for that:
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 laptop.
- Remove the battery of your laptop and start unscrewing the screws of the back cover using a screwdriver.
- After unscrewing the screws, carefully detach the back cover using a scale or similar object.
- Look for the CMOS battery panel at the corner of the motherboard area.
- Carefully remove the current CMOS battery from its slot. Remember to be very careful as the slot is fragile, and you may break it.
- After removing the battery, leave the slot empty for 15-20 minutes.
- Now, after the break, insert the new CMOS battery, and screw the back cover properly.
- Power your system and check if the laptop is turned on.
Fix 5: See Whether Dust Has Built Up
Sometimes, the Dell laptop won’t turn on because of excessive dust built up in it. This causes the machine to overheat and thus prevents it from starting up properly. To prevent this, you should open your laptop periodically and clean it.

Note: If you don’t possess the technical know-how or are a novice with computers, it’s best to bring in an expert for support since navigating through these steps involves complex tasks that can easily lead to irreparable damage to your laptop if done incorrectly. Also, do not open any laptops still under warranty!
To clean your laptop, follow these steps:
- Open up your laptop and clean any dust that has accumulated inside it using a soft brush or canned air.
- Make sure to disconnect the power cable before opening up the laptop to avoid any electric shock.
- Once you have cleaned the dust out of your laptop, plug it back in and try turning it on.
Fix 6: Check Start Button Functioning
If the Dell laptop powers on but the start button is not functioning, it could be due to a couple of issues. First, make sure that there is no dust or dirt blocking the button. If there is, use a can of compressed air to blow it away.
If that does not work, then the button may need to be replaced. This is usually an easy process, and most parts stores will carry compatible replacement buttons for your Dell laptop. But it is preferred to get it replaced by a professional.
Fix 7: Ensure It’s Not a Display Issue
Sometimes, the laptop may turn on, but there is no image display on the screen. Such a situation can be caused due to an issue with connecting cables or a faulty graphics card. To ensure this is not the case, try connecting an external monitor/TV and see if it displays any images. If it does, you will need to get a new screen for your Dell laptop.
If the external monitor/TV also doesn’t display any images, there could be an issue with your graphics card or motherboard. In such cases, it is recommended that you take the help of experts to diagnose and fix the problem.
Fix 8: Get Professional Help
If all these steps fail, it could be a hardware issue with your Dell laptop, like faulty components or bad connections. In that case, you need to take your laptop to a Dell Repair Center and get it professionally checked out. It is also important to keep in mind that prevention is the best way to avoid such issues in the future. So make sure to take proper care of your laptop and use it with caution.
