My Dell Laptop Won’t Turn On? Easy Guide to Fix It ASAP!

Your PC goes through various checks when you turn it on until booting into the operating system. This is normal; however, if you find yourself thinking, “My Dell laptop won’t turn on; what could be the problem?” you’re not alone. 

The issue could be stemming from various hard drive errors, power issues, power-on self-test (POST) process problems, and many others. 

In this guide, we’ll walk you through some common reasons and give you practical solutions to resolve this problem. By the end of this article, you’ll have the answer to the question, “Why won’t my Dell laptop turn on?” 

Let’s begin.

Why Won’t My Dell Laptop Turn On?

Your Dell laptop may have encountered one or more of the many problems that cause computers not to turn on when users want them to. These problems include:

• AC power adapter. Your battery may be drained because your AC adapter is faulty or incompatible with your computer. 
• Battery problems. Your laptop will struggle to turn when your battery health is degraded.
• Overheating. This can be another reason for the “Dell laptop not turning on” issue. Some internal components, such as your RAM, may malfunction due to exposure to excessive heat and prevent your computer from powering on. 
• Operating system errors. If the issue you’re experiencing is Windows’ inability to boot, it may be caused by operating system issues, such as corrupted system files, driver errors, and software application conflicts.
• Malware infection. Your Dell computer not turning on isn’t directly caused by malware. However, there may be an unusual setting due to malicious software, which can interfere with the boot sequence. 
• Hardware issues. Faulty RAM sticks, defective hard drives, and problematic peripherals can cause different versions of the “Dell computer not turning on” problem. 
• BIOS issues. Your laptop firmware may be out of date or corrupt, causing it to fail to initialize your internal components.

Now, let’s find the solutions to the question, “Why won’t my Dell laptop turn on?” 

What to Do When My Laptop Won’t Turn On

If your laptop shows no sign of life when you press the power button, then it’s not receiving any power. You can follow the fixes below to resolve the issue.

Solution 1: Perform a hard reset

A hard reset removes residual electrical charges, preventing the laptop from turning on. The process works if your computer does not turn on or refuses to go past the POST stage. Here’s how to do it:

• Turn off your Dell laptop. 
• Disconnect the AC adapter and remove the battery.
• Disconnect all external devices, such as USB drives, printers, webcams, and media cards. 
• Press and hold the power button for 15 to 20 seconds to drain residual power. 
• Reconnect the AC adapter, and then insert the battery back into the laptop. 

Press the power button to check if your issue with the Dell computer not turning on has been resolved.

Solution 2: Check your power adapter

If your power adapter is damaged, it will no longer charge your battery, leaving it drained. If the adapter has a power indicator, confirm whether it turns on after plugging it into your wall socket. You can also plug it into another power source.

If your Dell laptop won’t turn on, use a different power adapter to charge your battery or turn on your PC.

Solution 3: Check your battery

A faulty battery could also be the problem if your Dell laptop shows no power indicators. Follow these steps to troubleshoot the battery:

• Try to power the laptop without the battery. Unplug the charger, remove the battery, and plug the charger back in. 
• Press the power button to see if the laptop turns on. 
• If it does, then the battery is faulty and should be replaced.

Solution 4: Disconnect peripherals

Some peripheral devices, such as printers, SD cards, external mice, keyboards, and webcams, can also prevent your computer from turning on, going past the POST stage, or booting Windows.

So, disconnect them and try turning on your Dell laptop. If your laptop turns on after disconnecting the peripherals, one of them may be responsible for the issue. 

Now, plug one device back in and try restarting your computer. Continue the process until you identify the culprit for your Dell laptop not turning on.

Solution 5: Check your RAM

Random-access memory modules are one of the most common causes of your Dell computer not turning on. If your RAM is faulty, your Dell laptop computer may not turn on, show symptoms of the no POST problem, or not boot into Windows.

If you have two RAM sticks, remove one and try turning on your computer. You can then remove the other one if the problem persists. While rare, both RAM sticks can be faulty at the same time.

Consider using a working RAM module from a different computer to check. If your laptop still doesn’t turn on, move on to the next fix.

Solution 6: Confirm that your laptop’s screen is not faulty

If your Dell laptop is not turning on but the power is on, it’s possible that your laptop is working fine but your screen isn’t producing pictures.

If your Dell laptop is not turning on but the power is on, it’s possible that your laptop is working fine but your screen isn’t producing pictures.

While screen issues manifest in different ways, such as washed-out displays, lines, and artifacts, the screen may remain blank. 

Confirm whether your screen is faulty by connecting your laptop to an external display. 

If your Dell Latitude won’t turn on or it’s your Dell XPS that’s not turning on, most of these models allow you to connect to external displays using HDMI cables. 

That said, you can also use the regular VGA ports, if available.

Solution 7: Run the Dell diagnostics tool

Dell computers have built-in diagnostics that can help you dictate problems when the computer fails to load your operating system. 

The tool is called the ePSA (Enhanced Pre-Boot System Assessment). It tests your system memory, hard drive, screen, and other components to check for errors. 

Follow these steps to run the tests: 

• Turn off your laptop.
• Turn on your laptop and press the F12 button repeatedly until you see the boot options screen.

Select Diagnostics under Other Options.

• The computer will now start the series of tests and provide the results. The utility may ask to run an extended memory test, which may take up to 4 hours.

Solution 8: Check your hard drive

A faulty hard drive means your computer will fail to boot your operating system since Windows resides in the storage device. 

You can run checks to confirm whether your hard drive is the cause of why your Dell laptop won’t turn on. 

First, go to the BIOS environment to check whether your computer recognizes your hard drive. If it doesn’t, you have to open your laptop to check whether the drive has not been dislodged.

If the drive is damaged, replace it.

The Dell hardware diagnostics tool should report errors within the hard drive if there are certain logical issues. 

However, you can always use the Windows CHKDSK tool to find and remedy bad sectors that may be preventing Windows from booting.

Luckily, we have a guide on how to fix disk errors with the CHKDSK command!

Solution 9: Reset your BIOS

As mentioned, the BIOS may be corrupt or outdated. It could also be running on incorrect settings. When the BIOS is faulty, your computer will be unable to initialize or boot into Windows. 

You can resolve the problem by loading the BIOS defaults. If your computer does not go past the POST stage and you can’t get into the BIOS environment, you can open up your laptop and reseat the CMOS battery. 

It is a small battery on the motherboard that stores BIOS settings, and reseating it will restore your BIOS’s default settings.

You can also enter the BIOS environment to restore its default settings. Here’s how:

• Press your power button.
• Once you see power indicators, press the F2 key repeatedly until the BIOS environment appears.

Go to the screen’s bottom-right corner and click Restore Settings.

Follow these steps: 

• Turn off your laptop and connect your power adapter.
• Press and hold down the power button for 30 to 35 seconds until you notice the laptop’s LED blink three times.
• Release the power button, and the process is complete.
• You may have to return to the BIOS environment to set your time, boot sequence, and other settings.

Solution 10: Find and fix corrupted system files

Corrupted Windows files can also prevent your operating system from booting. You can resolve this problem by running the System File Checker (SFC) tool through the Command Prompt interface in the Windows Recovery Environment.

Solution 11: Run the Startup Repair utility

The Startup Repair utility focuses on fixing problems within Windows’s boot sector. These include corrupted boot files and wrong configurations.

If your Dell computer is not turning on: 

• Access the Advanced Startup Options menu by pressing the F8 key repeatedly. 
• When the boot menu opens, select Troubleshoot > Advanced Options > Startup Repair. 

The tool will scan your system for any issues and try to fix them.

Solution 12: Restore Windows

Some major changes, such as newly installed updates, drivers, and software programs, may prevent your computer from booting into Windows. You can easily resolve the problem by using the System Restore utility to undo those changes.

You can follow our system restore guide to take Windows to the previous state when you did not have to worry about startup problems.

Solution 13: Reset Windows

If your Dell laptop still fails to boot, consider resetting your operating system. You can perform the reset without deleting your files. However, you will lose your installed applications.

You can follow our Dell laptop factory reset walkthrough to reinstall your operating system and get your Dell laptop working again.
