Dell Laptop Won’t Turn On

If your Dell laptop is not even turning on, it might just need a hard reset. This is a simple procedure that works by clearing or resetting the hardware to get the laptop back to running properly again.

1. Perform A Hardware Reset:

  1. Turn off and unplug the laptop and remove the A/C adapter.
  2. Remove the battery if possible. Some laptops have internal batteries(see perform RTC below).
  3. Hold down the power button for about 20 seconds.
  4. Plug in the A/C adapter but not the battery just yet.
  5. Power on the laptop.
  6. If it works, go ahead and re-install the battery, you are all set.

If the steps did not fix the laptop power issue, continue on to the next set of steps.

2. Perform A Real-Time Clock(RTC) Reset:

If you have an internal battery or the above step did not work for you, do the following procedure. This will reset the BIOS back to factory settings. Note that RTC reset is available for certain Alienware, Inspiron, XPS, Latitude, and Precision Dell laptops.

  1. Power off the laptop.
  2. Ensure the A/C adapter is plugged in.
  3. Hold down the power button for about 30 seconds, until the LED flashes 3 times, then release.
  4. The laptop should boot and display the Dell logo screen.
  5. Enter the BIOS and re-enable your previous settings(date, time, etc) if needed.
  6. Double check the SATA drive settings for proper Windows booting.

Continue to the next step if you are still having issues.

Now we know the laptop is not powering on but is it getting power? We’ll check the LED status lights, the battery, and the A/C adapter.

3. Dell Laptop No Status Lights?

Check if the Dell laptop status indicator lights are working while the A/C adapter is plugged in. Your laptop might have a power light and a battery light. The battery light should be lit.

Check For Status Lights:

  1. Check the LED light on the A/C adapter itself to verify it is receiving power. Use a known good wall outlet.
  2. Also visually inspect the A/C adapter for signs of damage and replace as needed.
  3. If the A/C adapter LED is off, contact Dell support and replace the unit. If the LED is on, continue to the next step.

4. Dell Laptop No Display

Make sure the problem is not a bad display. A display screen not coming on can look like the Dell laptop is not powering up.

  1. Press the power button to turn on the laptop.
  2. Inspect for LED lights or any fan noise. Can you tell if it is getting power?
  3. Connect laptop to external monitor(if available) or boot into the BIOS as a test.
  4. Run display diagnostics by pressing down the ‘D’ key while powering on the laptop. Multiple colors should be displayed.
  5. If you get no response from the display, it is faulty and needs replacement.

5. Dell Laptop Battery Issues

Issues with your battery can prevent your laptop from booting or starting. In an earlier step, we removed the battery to try and isolate the power issue to the A/C adapter. In this step, we will check the condition of the battery.

  1. Examine the battery for signs of damage or bloating and replace(check warranty below) if needed.
  2. Reset the battery by removing it from the laptop.
  3. Boot the laptop using only the A/C adapter, then shutdown the laptop.
  4. Install the battery and try to boot.

Still no luck? Check if the battery is under a recall. And check the battery warranty status.

Knowing which component is failing on your laptop will give you a reference point to either reseat or replace that item.

Reseat Components On Dell Laptop

Reseating some of the internal components on the Dell laptop may fix the problem of it not booting. After trying a hard reset from the steps above, it is now time to open up the laptop.

What you are trying to do is get the laptop to its base configuration to isolate failing components. Remove each component and attempt to boot the machine. If it works you will know where the fault is.

Check the support website for your exact model on how to open up the laptop and access its components. Generally, you will follow these steps:

Steps To Reseat Internal Components:

  1. Either remove the back cover or just the memory access panel.
  2. Unlatch the memory modules and remove them, then re-install.
  3. Disconnect the hard drive, then re-install.
  4. Disconnect the internal battery(if equiped) and re-connect.

Try booting the laptop with only one memory module inserted to see if it will boot or make a beeping sound. This could tell you if the laptop still functions. Check out my article titled: Laptop Repair Primer (free guide) for additional information about repair steps.


The troubleshooting steps shown in the article will resolve the most commonly seen issues when a Dell laptop won’t turn on. The last resort if none of the above remedies work is to contact Dell support. Be sure to perform a hard reset, inspect the components and remove them for testing.
