Laptops like most products deteriorate over a period of use; therefore when a part like the power button stops working, don’t be surprised. It is difficult to know offhand how to turn on a laptop without a power button and our guide covers tips on how to work around this.
To turn on a laptop without the power button you can use an external keyboard for Windows or enable wake-on-LAN for Windows. For Mac, you can enter clamshell mode and use an external keyboard to wake it up.

There might be several reasons why your laptop fails to come on after tapping the power button several times. In such a scenario, you have to confirm that it is a hardware fault of the button itself.
Below, we explain some methods to try and if none of them work, then there might be something else wrong with the system.
Making use of a keyboard to power on a laptop is a setting that most laptops have. However, by default, this is always disabled. Prior to the power button developing faults, the user or owner should have taken preventive measures by enabling this feature to ensure the use of this method.
Enabling the use of an external keyboard to power on the laptop
To enable the use of an external keyboard to power on the laptop, you need to first access the BIOS settings. The steps are explained below:
Step 1a: Enter BIOS settings using F2 during startup
When you boot your PC, you will see the option to enter the advanced menu by either pressing the “F2” key or “DEL” key
Or
Step 1b: Enter BIOS settings using F2 during startup
You may already have your system on so instead of shutting down again to access the BIOS Setting, use the steps below:
Step 1b.1: Go to the “Settings” option in the “Start” menu
Step 1b.2: Select the option for “Update & Security”
Step 1b.3: Read through the options on your left and select “Recovery”
Step 1b.4: You will see a tab open with two sections.
Step 1b.5: Select “Restart Now” under “Advanced Setup”
Step 1b.6: A new window will pop up
Step 1b.7: Choose “Troubleshoot”
Step 1b.8: Select the “Advanced Options”
Step 2: Go to the “Power Management” or “ACPI Management” tab and press “Enter”
Step 3: Check for a setting “Power On By Keyboard” or “Wake On Keyboard” or something similar
Step 4: Use the “+” or “-” minus key to enabling the option
Step 5: Select a preferred key to power on the laptop
Step 6: Save and exit using the F10 key.
After carrying out the above steps, the next thing to do is to test that the settings will actually work.
Testing if the Keyboard Works
Step 1: Shut down the windows system
Step 2: Once it is off, press the selected key to power it back on.

Enabling Wake-On LAN for Windows 10
Just like waking up a laptop using a keyboard, using the LAN option requires prior enabling on BIOS.
How to activate Wake-On LAN with BIOS
Step 1a: Enter BIOS settings using F2 during startup
When you boot your PC, you will see the option to enter the advanced menu by either pressing the “F2” key or “DEL” key
Or
Step 1b: Enter BIOS settings using F2 during startup
You may already have your system on so instead of shutting down again to access the BIOS Setting, use the steps below:
Step 1b.1: Go to the “Settings” option in the “Start” menu
Step 1b.2: Select the option for “Update & Security”
Step 1b.3: Read through the options on your left and select “Recovery”
Step 1b.4: You will see a tab open with two sections.
Step 1b.5: Select “Restart Now” under “Advanced Setup”
Step 1b.6: A new window will pop up
Step 1b.7: Choose “Troubleshoot”
Step 1b.8: Select the “Advanced Options”
Step 2: Go to the “Power Management” or “ACPI Management” tab and press “Enter”
Step 3: Check for a setting “Power On LAN” or “Wake On LAN” or something similar
Step 4: Use the “+” or “-” minus key to enable the option
Step 4: Select a preferred key to power on the laptop
Step 5: Save and exit using the F10 key.
After carrying out the above steps, the next thing to do is to configure the network card to ensure it can power on the system.
Configuration of the Network Card
Step 1: Right-click the “Start” button
Step 2: Select the “Device Manager” option
Step 3: Wait for the “Device Manager” menu to open up
Step 4: Look out for “Network adapters”
Step 5: Right-click the menu
Step 6: Click the “Properties” option
Step 7: Go to the “Power Management” tab
Step 8: Tick the box for “Allow this device to wake the computer”
Testing if the Wake-on LAN Works
Step 1: Shut down the windows system
Step 2: Once it is off, plug in the LAN to power it back on.
It is important to note that the wake-on LAN configuration and ability to configure the network depends on your motherboard setting.
..the power button prevents the electricity from going beyond a certain point…
To power on a laptop, you need to ensure there is a battery present or the system is connected to a power source. The power from either of these two sources produces electricity that flows through the circuits within the laptop.
But, the power button prevents the electricity from going beyond a certain point.
However, when the power button is pushed, the outlet opens allowing electricity to flow to the rest of the laptop. When the same button is pushed, the laptop goes back to sleep.
Yes, you can install a new power button on your laptop once you notice that the previous one has developed a fault. If you want to carry out the installation yourself, follow these steps:
Step 1: Take out the battery, AC adapter, and back panel
Step 2: Remove the hard drive and RAM
Step 3: Remove the keyboard bezel
Step 4: Take out the keypads
Step 5: Remove the top frame and look for the power switch
Step 6: Remove the old switch and insert the new one
Step 7: Reassemble the laptop
What Does It Mean When My Laptop Fails to Come On?
..If your laptop fails to come on, then it must be facing a hardware fault…
If your laptop fails to come on, then it must be facing a hardware fault. However, this hardware fault maybe as a result of power supply to the system or a fault in other components of the hardware.
Therefore, the first thing you should do is check the power sources (battery and charger) before examining other components.

Conclusion
If after several attempts to turn on or off your laptop with the power button results in failure, it may be time to consider other alternatives. Try out any of the two methods explained above. However, in the event that none of them work out, then the problem might go beyond the power button.
It may very well be that your computer has other hardware problems which may include the ability to store power or a fault in the CPU. In such a situation you may have to seek expert technicians to diagnose the problem.
I have an acer laptop. Same problem as stated above.
I also have Acer Swift 3 NX.A4KSI.001 Laptop and it showing same problem.
I set my BIOS to wake on AC. I have a mobile pc desk and installed a power strip on the back to consolidate cords. I shut down my laptop normally. When I sit back down, I just reach to the back and switch the power strip off and on … voila.
I have a Sony laptop that’s always with me for work purposes but water poured on the key board and even after the technician worked on it it still isn’t working,but here’s the problem when I power it on I must press the enter botton before the screen can light but now it’s hard because I can’t use the keyboard.I’ll be glad if someone can help
