Laptop computer doesn't turn on
Troubleshooting a laptop that does not turn on or boot can be a lot harder than a desktop due to the inability to remove hardware. Below are troubleshooting steps to help identify what may be keeping your laptop from turning on. We recommend going through them in order for best results.
Connect the power cable
Although it may seem obvious, if your laptop is running on battery power only, connecting the AC adapter may solve the problem. Ensure the adapter cord is correctly plugged in on both ends securely. If the laptop works with the adapter plugged in, your battery is dead or defective.
Disconnect from docking station
If your laptop utilizes a docking station, disconnect it and try connecting the power cord directly into the computer. Then, try turning the laptop on.
Remove and reconnect the battery
Note: Many new laptops (especially MacBooks) are utilizing an architecture that does not allow their batteries to be removed.
The laptop can also be in a power state preventing it from booting properly. Try disconnecting the power cable and then removing the battery from the laptop. Leave both disconnected from the laptop for at least a minute. After you wait, put the battery back into the laptop, connect the power cable, and try turning the laptop on again.
Drain the computer of electricity
Sometimes a residual electrical charge can keep your laptop from turning on. You can think of it as an "electricity clog." By performing the following steps, you effectively drain your laptop of any electricity and start over, which can result in it powering up.
- Disconnect the AC adapter and remove the battery.
- Hold down the power button for at least thirty seconds.
- Without replacing the battery, plug the AC adapter back into the laptop.
- Press the power button to turn on your laptop.
Note: If this process did not work for you, repeat and hold the power button for one minute or longer at step two.
If you have gone through all of the sections above and your laptop continues not to turn on, it is likely a hardware component inside the laptop has failed. We suggest contacting the manufacturer of the laptop for recommendations on how to get it repaired. You can also take your laptop to a computer repair shop as they may be able to diagnose the issue and replace faulty hardware.
