How do I start my Dell laptop if the power button is not working?

Having trouble turning on your Dell laptop because the power button doesn’t seem to be working? Don’t worry, there are a few troubleshooting steps you can try to get your laptop powered back on.

First Steps

Before digging into more complex solutions, try these basic first troubleshooting steps:

  • Make sure the laptop is plugged into a power source and the adapter is fully connected to both the outlet and laptop.
  • If the laptop uses a removable battery, remove and reseat the battery to make sure it is properly connected.
  • Make sure the laptop is not simply turned off or in sleep mode. Try holding down the power button for at least 10 seconds to see if it will turn on.
  • Connect the laptop to an external monitor to see if it is booting up but just not displaying video.

Often a loose power connection or battery is the culprit behind a seemingly unresponsive power button. Trying the steps above may power the laptop back on before moving on to other solutions.

Bypass the Power Button

If the basic steps above don’t work, the next thing to try is bypassing the power button entirely. The power button itself may have failed, but there are a couple ways to power on the laptop without using it:

  • Remove the battery and unplug the laptop. Hold down the laptop’s power button for 30 seconds to drain any residual power. Put the battery back in and plug the laptop in. The laptop may power back on.
  • Open the laptop case (typically by removing some screws on the bottom) to access the internal motherboard. Locate the small “power switch” connector on the board and briefly bridge the contacts with a screwdriver tip or paperclip. This should start the boot process.

By manually powering on the laptop using one of these methods, you can bypass any issue with the power button itself failing. Be very careful when poking around inside the laptop though – only bridge the power switch contacts for a second or the motherboard could be damaged.

Check for Damage

If you still can’t get the laptop to turn on, the issue may be more serious than just a stuck power button. Here are some things to inspect closely on both the outside and inside of the laptop:

  • Check for external damage like impacts or liquid spills that could have damaged internal components and be preventing power on.
  • Check the power button itself for any external damage or broken parts that could be preventing it from working.
  • Once you access the inside of the laptop, inspect the motherboard for any damaged electronics or issues like liquid corrosion.
  • Examine the DC power jack where the adapter plugs in to make sure the connector isn’t loose or broken.
  • Look for any obviously damaged or disconnected cables inside the laptop related to power delivery.

Damage to any of these components could cause the power on issue. If there is obvious external or internal damage that could be related, it may require replacement of parts or professional repair to get your laptop working again.

Remove and Check Hardware

Another troubleshooting step if you’ve narrowed the issue down to a potential hardware fault is to minimize the components connected and try powering on again. Here are a few things to try:

  • Remove any external devices connected like USB drives, printers, external monitors.
  • Open the laptop and remove any extra RAM sticks or hard drives.
  • Remove the wireless card and battery.
  • Only reconnect the bare minimum parts needed to power on the motherboard.

If you can systematically isolate the issue to one faulty component preventing boot up, it again indicates hardware damage or failure is the root cause. From there, replacing the specific failed part may resolve your no power issue.

Motherboard Issues

Given that the power button and related circuitry connect directly to the motherboard, an underlying motherboard failure is a real possibility if all else fails. Some signs of a bad motherboard that could prevent powering on:

  • You’ve narrowed down the issue to the motherboard itself with all other components removed.
  • There is visible damage to the motherboard or burnt/discolored spots.
  • You get response from onboard LEDs but still can’t power up fully.
  • The laptop powers on intermittently or only when positioned a certain way.

Motherboard issues can be difficult to conclusively diagnose. If you suspect the motherboard and can’t isolate the fault further, replacement may be the surest solution. Dell generally provides motherboard schematics and replacement parts for their laptops years after initial release.

Contact Dell Support

If you’ve worked through all of these troubleshooting tips and still can’t pinpoint the specific reason your Dell won’t power on, reaching out to Dell’s technical support team would be the next step. Here are some things Dell support can help with:

  • Walk you through additional advanced troubleshooting steps specific to your model.
  • Help diagnose if the issue is a particular failed component or larger problem.
  • Send replacement parts if needed, whether under warranty or for purchase.
  • Arrange professional repair service if that is determined to be necessary.

Dell’s techs have experience with many different issues preventing laptops from powering up across Dell’s product line. Reaching out to them can shortcut your own trial-and-error process. Depending on warranty status, they may be able to fix the laptop for little to no cost as well.

Summary of Troubleshooting Steps

To recap, here are the main troubleshooting steps to try if your Dell laptop will not turn on due to the power button not working:

  1. Make sure connections and components are properly seated.
  2. Attempt to power on without using power button.
  3. Check for external and internal damage.
  4. Minimize components and retest.
  5. Consider possible motherboard failure.
  6. Contact Dell support for assistance.

With some systematic testing and isolation of the issue, you should hopefully be able to determine what is preventing your Dell laptop from turning on normally and take action to fix it. Power on issues can arise from minor failures but can also indicate serious component damage. Getting the laptop operational again may require part replacement or professional repair in some cases.

Troubleshooting Step Details
Check connections and reseat components Make sure power adapter, battery, and internal cables are properly connected
Bypass power button Drain residual charge then force reboot with power switch or paperclip
Inspect for external and internal damage Look for liquid spills, impacts, broken parts, etc.
Remove extra components and retest Isolate faulty hardware by removing RAM, drives, wireless card, etc.
Consider motherboard issues Problems could stem from damaged motherboard connections or circuitry
Contact Dell technical support Dell can provide advanced troubleshooting, part replacement, and repair services


While a non-functional power button can be frustrating, methodically working through these troubleshooting techniques should help identify what is preventing your Dell laptop from turning on. With some focused hardware testing, you can hopefully isolate whether it is a loose connection, damaged power components, bad motherboard, or some other issue at the root of the problem. Getting assistance from Dell’s support team can also help diagnose and address the specific failure. With the right replacement part or repair, you’ll hopefully be able to get your laptop powering back up properly.
