Laptop computer doesn't turn on

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

Troubleshooting a laptop computer that doesn't boot can be a lot more difficult than a desktop computer, because of the inability of being able to remove hardware in the computer. Below are troubleshooting steps to help identify what is causing a laptop from booting.

Connect power cable

Power cableIf your laptop is only running on battery power, connect the power cable to make sure the battery is not dead and causing this problem. Make sure 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's not the cause of your issue.

Remove any external peripherals

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

Remove and reconnect battery

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

Bad hardware

If after following the above steps your laptop computer continues to not turn on, unfortunately, it's likely a component within the laptop has failed. We suggest contacting the manufacturer of the laptop for recommendations on how to get it repaired.
