Laptop computer doesn't turn on

Note: If this is a desktop computer, follow the POST troubleshooting steps.

Troubleshooting a laptop that does not boot can be a lot more difficult than a desktop because of the inability to remove hardware from the computer. Below are troubleshooting steps to help identify what is keeping your laptop from turning on.

Connect power cable

Power cableIf your laptop is only running on battery power, connect the power cable to make sure a dead battery is not the cause of the problem. Ensure the cable is properly plugged in on both ends.

Disconnect from docking station

If your laptop is connected to a docking station, disconnect it to verify it is not the cause of your issue.

Remove any external peripherals

While troubleshooting this issue, disconnect any peripherals such as an external mouse or USB devices, to make sure they are not the cause of your issue.

Remove and reconnect battery

It is possible that the laptop could be in a power state preventing it from booting properly. Try disconnecting the power cable and then removing the battery from the laptop. Once done, leave both disconnected from the computer for at least a minute. After you wait, put the battery back in the computer, connect the power cable, and try turning the computer on again.

Drain the computer of electricity

Sometimes a residual net charge can keep your machine from turning on. If you would like, you can think of it as an "electricity clog." By performing the following steps, you effectively drain your computer of any electricity and start over; often resulting in it powering up.

  1. Disconnect the power cable and remove the battery.
  2. Hold down the power button for no less than one minute.
  3. Without replacing the battery, plug the power cable back in.
  4. Press the power button to turn on your laptop.

Note: If this process did not work for you, repeat and hold the power in for 2-3 minutes in step two.

Bad hardware

If you have gone through all of the previous sections and your laptop computer continues to not turn on, it is likely a component within the laptop has failed. We suggest contacting the manufacturer of the laptop for recommendations on how to get it repaired.
