How to Turn On Laptop Without Power Button? – (6 Easiest Ways)

There are plenty of different ways you can turn On your laptop without a power button. For example, short-circuiting the (power button) connection on the motherboard, connecting the laptop to a wall socket (while its battery is out and power cable disconnected from the board), via CMOS battery method, via keyboard, via laptop lid, and using the wake-on-LAN method, etc.

Well, I know there is nothing more frustrating than seeing your laptop becoming a brick – unresponsive because the power button has suddenly stopped working. The situation gets even more annoying when you have to make and submit an urgent assignment within the next hour.

I understand how negative you’ll be thinking at such a moment not being able to figure out how to turn On laptop without power button. Isn’t it?

But don’t be worried as we are just going to see a very detailed touch on this thing below. So come along me.

Different Methods to Turn On Your Laptop Without Power Button

Apart from replacing the defective button and installing a new one, there are six other sure ways (all named above) you can get over this situation. Three of those six methods are, sort of, preventive approaches you must take beforehand to avoid such a thwarting scenario.

Whereas, the other three are post-incident measures for when you are finally hit by such an incident and you don’t know the quick-fix at that moment. So let me highlight them first.

Preventive/Proactive Measures (To Avoid and Then Fix Such Issue(s))

The three pre-incident measures include:

  1. Using Keyboard – Setting up alternative/backup power buttons on the keyboard so that if the power button malfunctions, you can use those keys to power On your machine.
  2. Via Laptop Lid – Setting up/configuring the BIOS settings so that your laptop turns On when you open the lid.
  3. Via Wake-On-LAN Method – Enabling the wake-on-LAN settings in your BIOS and configuring your network card in advance so that it can power On your laptop.

Quick Fixes – When the Laptop is Off and Power Button Not Working

These include:

  1. Via motherboard
  2. With the help of a wall socket/extension
  3. Using CMOS/Clock Battery method

Let me now explain in detail how each of these methods works.

How to Turn On Laptop Without Power Button?

All things discussed above are still making it to a very short answer which is not enough for sure. And that’s pretty rude too. So here is a comprehensive take on all the different approaches you can assay when you are struck by such an unwanted scenario.

Do remember that all these methods would only work in case of the power button disrepair(s). But if your laptop is not turning On because of any other issue like charge drain, faulty battery, defective power supply (charger port), etc., you may need to reach out to a technician to probe the actual defect.

#1. How to Turn Laptop On Via Motherboard?

Trying turning the laptop On from the motherboard straight is the most certain, the most definitive method of all. It should work for you (and it just works all the time) doesn’t matter what and how easy or severe the power button issue is.

Here is a step-by-step guide on how to do it.

  1. Unplug your laptop if it’s connected and remove the battery as well.
  2. Reach out to the power button region on the motherboard (either by opening up the keyboard cover and revealing the motherboard or disjoining the back cover).

At times, completely removing the defective button only can also do the job. But that’s a bit of an exceptional case.

  1. You’ll now be seeing some 3 to 6 connection tips/pins over there on the motherboard (exactly underneath the power button).
  2. Grab a conductor like a screwdriver or tweezer, etc., and short-circuit those pins (usually, pin 1 and 3). Or simply connect them with a wire.
  3. Upon connecting those pins or pressing them together they complete a full circuit (because that’s where the two connections meet), and you see your laptop turning ON right away.

And that’s it for this method. Make sure you get a replacement button soon or try other methods, as this one can pose threats to your motherboard if tried multiple times. And professionals never recommend doing it every other day.

#2. Turning On the Laptop with the Help of Wall Socket/Extension

In the simplest possible words, this method means turning and keeping your laptop ON straight from the Main/AC (without battery). It’s one of the best tech quick-fix, not only because you won’t be short-circuiting your board but because it works for pretty much every laptop model whether it’s HP, Dell, Acer, Asus, Lenovo, or anything else.

But if in some rare cases a laptop won’t turn ON directly on AC, you’d need to toggle and enable it from its BIOS settings.

  1. Again, unplug the charger first, remove the battery, and access the motherboard.
  2. Locate and disconnect the cable that’s connecting the power button to the motherboard.
  3. Reassemble the laptop but keep the battery out and connect your laptop to the AC socket. Wait for a second as the laptop will turn On soon.
  4. To disconnect the laptop from the power socket (and turn it off), just put the battery back into it. And that’s it.

#3. How to Turn Laptop On Using CMOS/Clock Battery Method?

Complementary Metal Oxide Semiconductor (CMOS) is a lithium coin cell – a battery that powers the BIOS firmware in the laptop. Removing this CMOS, also called Clock Battery, can also do the trick and power ON the laptop in case of laptop power button failure(s).

But there are two flaws with this method as well. The first one is that it’s a highly technical job so you most of the time need to get to a professional repairman (or need to practice the highest care if doing yourself). And the second flaw is that it always brings your laptop to the factory settings.

Anyways, here is how you can try this method out.

  1. Disjoin the back hood and completely disassemble your laptop.
  2. Disconnect all the cables and connections from your motherboard.
  3. Carefully disconnect the battery cable/ribbon from the board. Remember battery cable is different from charging cable.
  4. Unscrew the motherboard completely, take it out, and remove/disconnect the clock battery from it.

Once you are done, reassemble things up and connect the charger. You’ll see your (brand new – factory restored) laptop waking up soon you plug it in.

#4. How to Turn On Laptop via Keyboard?

As already said, this is a proactive approach where you need to take preventive measures and enable this BIOS feature before any such disrepairs occur. The application of a backup keyboard key to power ON your laptop is enabled only from your BIOS settings.

Follow these steps to know how it’s done.

  1. Enter the BIOS settings
    1. If the laptop is already OFF, you can turn it ON via other methods discussed above. When the laptop boots up, press F2, F10, Del, or whatsoever button suggestion you see (depends on laptop’s manufacturer and model) to get to Advanced Menu/BIOS.
    2. If the laptop is already ON (and you know there is a defect in its power button and so such an issue may take place), enter the BIOS settings as follows: Go to Settings > Update & Security > Choose “Recovery” from your left > Click on “Restart Now” under the “Advanced Setup” on the new screen. On the newly appearing window, click on “Troubleshoot” > and finally, “Advanced (Options)”.
  2. Upon entering the BIOS settings, look for “Power Management” or “ACPI Management” (it’s usually under the “Advanced” tab in BIOS) settings and click “Enter”.
  3. Locate a setting named “Power On (Wake On) by Keyboard” or something alike.
  4. Toggle the setting to “Yes” and choose and configure the preferred backup key that you’ll now-on use to wake your laptop when it’s Off.
  5. Save the settings and Exit.

Then shut down your laptop again and turn it back ON pressing that selected key to see if the BIOS settings were successful and the changes are working properly.

#5. How to Turn On Laptop Without Power Button with Lid?

Another preventive measure to keep such issues from happening is to configure your BIOS settings and enable your laptop lid to power Off/On your laptop. So if your laptop, upon closing its lid, used to go to sleep mode only before, it will now turn Off with that. And vice versa for the open lid.

To enable this setting:

  1. Reach out to and enter the BIOS settings (follow the steps discussed in the previous method).
  2. Get to the “Advanced” menu in BIOS and once again access the “Power Management” settings.
  3. Look for the “Power On with (Open) Lid” option/setting over there and toggle it On.

And it’s done. Save the settings and exit. Close the lid first to see if the laptop shuts down and then open it to see if the laptop comes back live.

#6. Using the Wake-On-LAN Method to Turn On Laptop Without Power Button

Last on the list is also a pre-incident preventive method where you configure your network card and enable it to wake your computer up (even remotely) if the power button malfunctions. For this:

  1. Enter the BIOS menu (following the steps discussed above) > Advanced tab/menu > Power Management.
  2. Seek out “Wake on LAN” or “Power on LAN” settings there and enable it – toggle it ON.
  3. Here again, select a (preferred) key that will then power ON your laptop.
  4. Save the settings and Exit.

But that’s not only enough as now you have to configure your network card as well so that it can then start your laptop up.

Configuring the Network Card

To set up your network card so that it knows to power up the system when you press that keyboard key, you need to follow these steps.

  1. Go to “Device Manager” (either from the start menu or by pressing Windows and X keys at once and selecting it from the list that pops up).
  2. Seek out “Network Adapters” within the device manager and double-click on it.
  3. Select the adapter from the drop-down > right-click on it > select “Properties”.
  4. In the new windows, get to the “Power Management” tab.
  5. Check the “Allow this device to wake the computer” box. Check the “Wake on magic packet” box too.
  6. Save the settings and Exit.

If you are a Mac user, you can configure the network adapter as follows: Enter “System Preferences” > get to “Energy Saver” tab > and check the “Wake for network access” box.

To check out if it’s working properly, power OFF your laptop and plug in the LAN cable when you want to turn it ON again. As soon as the LAN network starts, your laptop will right away wake up upon pressing that selected key.

Well, remember that setting up this wake-on-LAN feature, configuring the network, and its application depends on your motherboard firmware and settings.

How to Replace/Install A New Power Button?

Compared to all these unusual configurations and weird fixes, a replacement key is much more permanent and absolutely a better option to go for. And if you are thinking of getting rid of the faulty button and installing a new one in its place, you can easily do it yourself.

  1. Unplug your laptop from Main, remove the battery (if removable), and disjoin the back cover.
  2. Take out all the other secondary (removable) things like RAM, HDD, etc., and remove the keyboard frame as well.
  3. Remove the top keypad frame and access the power button location.
  4. Pull out the old faulty key and install the new one.
  5. Reassemble the laptop back.

Your laptop should start, as it always did, with a single key tap now. But if it’s still resisting to turn ON, there might be some other issue(s) with it like a faulty power supply, etc. So do check out all such possible hardware-software issues first before trying different complex things.

How can I turn on my laptop using the keyboard?

Firstly, you have to enable the “Power on by Keyboard” option in the “Power management” and then choose a specified key to power on your laptop with the help of the keyboard.

How can I turn on my computer without the power button?

If your laptop power button has malfunctioned or isn’t working at all, you can head over to BIOS mode where you can toggle the “Wake on Keyboard” or “Wake on LAN” option to turn your computer back to life.
