Laptop Power Button Not Working? Here's How To Fix It – Tech News Today

Science & Technology

With its extensive use case, it’s not unusual for the power button to get faulty. However, when the power button malfunctions or becomes unresponsive, you won’t be able to log in or turn off your device easily.
If your laptop’s power button is stuck or simply fallen off, you can try cleaning the area and reattach it. Or, restarting your device may also help you fix the issue. However, if the power button has other hardware issues, it may require additional repairs.
In this article, we’ll first look at the possible causes and then check out the fixes to make your laptop’s power button operational again.
Some common reasons why the power button of your laptop has stopped working are:
In simple terms, a power button completes a circuit to turn on your device. When pressed, the pins on the power button connect with the pins on your motherboard which sends instructions to provide power and turn on the laptop.
There can be numerous reasons why the power button in your laptop may have stopped functioning. From reasons that include both the hardware and the software, finding exactly what is causing the issue may be difficult to diagnose. 
Therefore, we’ll be going through multiple fixes that may help if the power button is malfunctioning or not working:
Before disassembling your laptop, first ensure if the issue is caused by your device not having enough power. Connect your device to the AC adapter and let it charge for a while. 
If your device is charging, press the power button to see if it works. If your device refuses to turn on, you can move forward with the fixes mentioned below.
Similarly, any breakages, fault or issue in the connections and components can cause the power button to not function. If the tiny gaps between and under the power button have any dirt or dust particles embedded, it may cause the power button to get stuck.
If your laptop has a modular power button, you can directly attempt to clean or repair it from the outside by using a soft brush and Isopropyl alcohol without disassembling your laptop. Otherwise, follow these steps:
Note: Attempting to fix your laptop or by third-party may void the warranty.  Consult your manufacturer or product webpage for detailed information beforehand.
If you find any issues, you can try and fix them by rewiring or soldering the components together. If you do not have the right equipment, please take your device to a repair shop or a technician for servicing.
Every component has to work in sync in order for the laptop to power on and function properly. If your laptop’s power button does not have any visible damages or impairments, the problem may be because of other hardware issues. 
Components like batteries, display units, RAM and the motherboard could be faulty and cause your power button to not function properly.
Do the following to see if the components of your laptop are damaged besides the power button:
If you have installed any third party software that manages or handles power delivery to your device, that may be causing the power button to function improperly.  Some third party apps may also cause the power button to be disabled. To solve these issues, you can uninstall any third-party power management applications. Or, restart your device to see if the problem is solved.
Some power management settings from Windows can also cause the power button to be disabled. If your device has set the power buttons to Do Nothing in settings, the power button in your laptop will not work. To change this:
Your laptop’s power button should be functional.
If you have access to an external keyboard that has the power button built into it, you can try and turn your laptop on or off by this method. To do this:
Shorting the connectors can also be done if they are intact and only the power button is damaged. To do this, 
Note: Only try this if you have enough information on how to do it. You can potentially damage your device or risk getting electrocuted.
If your device is on and the power button is not responding, your issue is likely caused by the software. If you have an unreliable power button and think that it may stop working anytime soon,  you can try these software fixes and preventive measures.
Sometimes a bad software update, malware or abrupt crash can cause the system files of the OS to get corrupted. This may cause the power button to not work or act finicky.  You can try and fix this by repairing corrupt files or performing a system restore.
If the above methods do not solve the issue, you can try to reinstall ACPI drivers from device manager. You can also update the ACPI drivers from Windows Update. 
To do this, go to:
If none of these methods work out, your best option is to remove the storage device and backup the data. Contact a technician or the manufacturer to see if they can solve the issue. If the device has warranty left, you can request a repair or an RMA and exchange it for a new laptop.
