If your PC’s power button isn’t working, you can still turn on pc without power button on the motherboard, using a keyboard shortcut if supported, or enabling Wake-on-LAN for remote startup. These methods allow you to power your desktop safely without needing immediate hardware repairs.

Key Takeaway
- Shorting the power switch pins on the motherboard is the fastest and safest immediate fix. [1]
- Enabling keyboard power-on or Wake-on-LAN offers convenient remote or alternative startup options.
- Proper BIOS configuration and safety precautions prevent damage and ensure reliable results.

Shorting the Power Switch Pins on the Motherboard
Over the years, plenty of folks have asked us to show them the simplest backup for a dead power switch. This solution’s tried and true, and probably the most direct. Here’s the thing: every desktop pc has two pins on the motherboard designed for the power button, known as the power switch pins. If you can momentarily “short” these pins, you complete the same circuit the power button does.
In a job we did down in Miranda, the owner was sure the machine was dead for good. We talked her through it. Unplugged the power cable first – nobody wants an accident. Opened up the case, took good care not to bump any loose cables.
Once you spot the front panel header (that’s usually where the cables from the pc power button connect), look for small text on the motherboard – “PWR SW” or “POWER” is the giveaway. We always suggest checking the motherboard manual to confirm which pins are the right ones. Manuals don’t get enough love, they truly don’t.
For the actual short, we use a small screwdriver – flathead works best, but a paperclip or even the metal end of tweezers will do fine. Very gently, touch just the two correct pins, hold for a split second, and as soon as the fans kick in, hands off. That’s it. If all goes right, the desktop computer comes to life. We stick around to make sure nothing else needs doing.
It goes wrong when folks are in a rush. You don’t want to short more than two pins, or linger too long. Some DIY attempts we’ve seen have cost people a motherboard – static electricity is no joke. We remind people: ground yourself by touching something metal before you try, and when in doubt, ask us. We’re always happy to assist.

Quick Reference Checklist (as we show clients)
- Shut off and unplug the computer first.
- Ground yourself against static.
- Open the case with proper tools.
- Identify the front panel header and check manual.
- Locate “PWR SW” or “POWER” pins.
- Use screwdriver or paperclip, touch only those two pins briefly.
- Remove tool instantly when the system starts.
We never treat this like a one-size-fits-all. Some boards have tricky layouts. Some small office PCs are missing labelling. But with a patient, careful approach, this gets most people up and running within minutes.
Using a Keyboard to Power On
Now and then, we get surprised looks when we ask, “Did you know some computers can start with the keyboard?” Really, it’s not a myth, but not every desktop pc has this enabled by default. Whether you’re a gamer with a custom build or a busy receptionist, it’s worth checking your motherboard’s capabilities.
We guide clients into the BIOS – on startup, usually press Delete, F2, or maybe F1, depending on your machine. Inside, you want the power management section. We look together for a setting called “Power On By Keyboard” or sometimes “Keyboard Power On.”
Once you activate it, select a specific key (many choose Enter or Spacebar for convenience). Save the setting, exit BIOS, shut the pc down, and give your chosen key a tap.
Here’s where a bit of complexity enters. Not every motherboard’s BIOS has this feature, and some systems need a wired USB keyboard – wireless ones don’t always work for this function. Some motherboards only work with older-style PS/2 keyboards, which can frustrate people without the right gear. It’s always a good idea to check the manual or give us a call.
For office managers who hate opening the case, enabling keyboard power-on feels safer and faster than tinkering near the motherboard. We even had one client install an external keyboard under their desk just so the staff could boot office computers this way – strange fix, but it worked a treat in their workspace.

Main Steps for Keyboard Power-On
- On startup, press Delete, F2, or F1 to enter BIOS/UEFI.
- Find “Power Management” or similar in BIOS menu.
- Enable “Power On By Keyboard.”
- Set a preferred key (often Enter, Space, or Power).
- Save settings and exit BIOS.
- Test the function with keyboard after shutdown.
- Use wired USB or PS/2 keyboard if possible.
This method brings comfort and a little peace-of-mind, particularly for those with tricky setups – retail counters, desks with no easy access to the case, or multi-user environments. We find that talking owners through BIOS menus, even just once, gives them confidence for years.
Wake-on-LAN (WoL) for Remote Power-On
More and more, our business clients have been asking for remote solutions. Sometimes you’re at home and need to wake a desktop at the office, or you’re just running late and want it ready to go. Wake-on-LAN is a setup we’ve implemented in dozens of Sydney workplaces. [2]
This relies on network cards and operating systems that support it. In BIOS, once again, we enable “Wake-on-LAN,” then move to Windows and allow the network card to wake the pc. The system needs to stay connected via power, and always by Ethernet (not Wi-Fi). We usually install and test a WoL app on another device – say, the owner’s laptop or mobile – to make sure it can send the magic packet.
The process sounds technical, but once you get it working, it makes a big difference. Offices with remote staff or managed IT departments (that’s where we come in) find this convenient and surprisingly reliable when properly configured.

Steps for Setting Up Wake-on-LAN
- Enter BIOS/UEFI as before (Delete, F2, etc.).
- Enable “Wake-on-LAN” or similar in power/network section.
- Save and exit.
- In Windows, open Device Manager > Network Adapters.
- Right-click network card, select Properties.
- Under “Power Management,” tick “Allow this device to wake the computer.”
- Connect computer to Ethernet (not Wi-Fi).
- Test with a WoL app from another device on the same network.
Some troubleshooting is usually required the first time – firewall rules, network settings, or even a router/ISP issue can stand in the way. We stick with our clients for as long as it takes to get those final details working.
We’ve also seen the odd mistake – a client once sent the magic packet over Wi-Fi, no dice. After switching to Ethernet, it worked straight away. When things are tricky, a quick support call to us can save hours.
Smart Relay and Power Outlet Methods
With the rise of smart homes and connected offices, a few of our clients have asked us to install smart relay switches or use smart power outlets as another way to control their pcs. We don’t recommend these for everyone, but in certain scenarios, they’re a godsend.
A smart relay switch is a small electronic device that wires into the motherboard’s power switch pins, essentially standing in for the physical power button. You can control the relay via a phone app, voice assistant, or remote trigger. This suits businesses where machines are locked in racks or out of easy reach.
For smart power outlets, we enable a setting in BIOS (“Restore on AC Power Loss” or “Always On”). This tells the motherboard to boot when power comes back. When the smart outlet is switched off and then on again, it acts like someone turn on pc without power button.
We set these up for one of our hospitality clients whose pos systems needed to reboot after power cuts, even when staff weren’t on site. We reminded them that it’s not for daily control – cycling the power this way too often can wear down hardware.
Key Steps and Considerations for Smart Relay and Outlet Use
- Smart relay: install carefully on motherboard’s power pins.
- Choose compatible relay; we always use recommended brands.
- Set up app or smart home integration for remote trigger.
- For smart outlets: turn on “Restore on AC Power Loss” in BIOS.
- Use with compatible smart outlet, test with a controlled on/off.
- Use these methods only occasionally or when physical access is limited.
We’re cautious when advising this path. Done right, it’s wonderful for busy or multi-location setups. But we always check compatibility, and we help our clients understand the wear and tear factors.
Methods for Laptops

Turn on pc without power button
Laptops are trickier. We’re asked all the time – can I start my laptop with just a keyboard? The answer is sometimes yes, sometimes no. We always check BIOS as the first step; occasionally, we’re pleasantly surprised.
We walk clients through pressing F2, F1, or Delete during start-up. If “Power On By Keyboard” (or an option with a similar name) appears, we’ll turn it on. The external USB keyboard then may be set to wake the laptop. In rare cases, specific key combinations are available.
We worked with a travelling financial advisor who hated opening her lightweight laptop. Turning on from a keyboard made her day easier. But on other jobs, we’ve found the option’s simply not there. Take a look first, or reach out – we’ll be honest if it’s not in the cards.
Considerations for Laptop Power-On
Here’s a quick rundown of what we check:
- Does the BIOS have the keyboard wake feature at all?
- Is the laptop model recent enough to support it?
- Will an external USB keyboard work, or is it limited to the internal keyboard?
- Have you already tried manufacturer documentation for specifics?
Sometimes you’ll need the original laptop charger plugged in for the key to work. If it just doesn’t start, don’t force it. Ring us so we can safely test connections, keyboard compatibility, and settings.
Safety and Preparation
It’s our habit to walk every client through safety first. The number of times we’ve shown up after a blown fuse or fried motherboard – rather not count. Safety always:
Start by turning off the power and unplugging the supply. Before touching anything inside, ground yourself by holding a piece of metal – or, if possible, use an anti-static wrist strap. We recommend working on a flat, stable surface, away from loose drinks or snacks. Some devices, especially business desktops, have side panels that need a specific screwdriver (Philips or Torx are common).
Whenever you need to short the power pins, use only a tool with a plastic handle and never touch any other components or connectors. We remind clients to put every screw and side panel in a dish or bag so nothing gets lost. Precautions save headaches and save money – there’s no shame in taking things slow.

BIOS and Power Settings
BIOS access is usually second nature to us now, but it can be intimidating for anyone unfamiliar. Different brands and models use different access keys – Delete, F2, F1, or Esc. We encourage everyone to write down which one works, or just let us help.
Once inside, we help you review power management settings. We:
- Enable “Power on by Keyboard,” “Wake-on-LAN,” as required.
- Look for “Restore on AC Power Loss” for smart outlets.
- Review fast startup, sleep, and hibernation modes in Windows to make sure wake functions work right.
- Suggest adding a BIOS password for anyone with sensitive or shared office equipment.
Each change gets saved before rebooting. If you’re allergic to BIOS menus, don’t worry. We’re happy to jump on the phone, share our screen, or visit in person to handle the trickier bits.
Troubleshooting Common Issues
We’ve tracked plenty of late nights to the simplest of problems. When something fails, we go back to basics.
Most times, it’s a loose power cable, an unplugged wall socket, or a tripped surge protector. Sometimes clients have mistaken fan or light cables for power switch pins. A little tension or a rushed moment can cause mistakes that delay everything.
If you’ve tried shorting pins and nothing happens, check:
- Are you on the right pins? Cross-check with the manual or motherboard diagram.
- Is the power cable fully plugged into both the wall and computer power supply?
- Have you grounded yourself before touching inside?
- Did you unplug the computer before opening and reconnect after working inside?
- Is your tool (screwdriver, paperclip) actually conductive and clean?
For keyboard start issues, we step back:
- Is the BIOS setting enabled and has it saved?
- Is the keyboard plugged in and working in other situations?
- Wired keyboards are more reliable here than wireless.
For Wake-on-LAN, give this a quick look:
- Both devices need to be on the same local network.
- BIOS and OS settings for WoL must both be enabled.
- Network card must specifically support WoL – some cheaper adapters simply don’t.
- Avoid sending the WoL magic packet over Wi-Fi – stick to Ethernet.
If a pc power button itself is physically broken – loose, sticky, or not clicking – sometimes a quick fix or button swap will do. For desktops, parts are cheap and accessible. For laptops, it’s fiddlier, and we suggest leaving most repairs to us unless you’ve got prior electronics experience.
Additional Considerations
Not every method works for every setup. We have owners who value the fastest fix possible – shorting pins suits them best. Others want more control, so keyboard wake or Wake-on-LAN is preferable. Some ask us for smart relay installs when machines are hidden or locked up.
For laptops, we’re always clear – it’s hit or miss. Check the manual, run through BIOS, and see if a USB keyboard will cooperate, but don’t force things.

FAQ
What are the steps for starting a desktop computer without using the original pc power button, especially if the button is broken or missing?
Starting a desktop computer if the power button is broken involves careful steps. First, always unplug the power cable and ground yourself to avoid static damage. Open the desktop case and find the motherboard’s front panel header, where the power switch pins are. Use a screwdriver to briefly short the two pins labeled for the power switch.
This acts like turn on pc without power button. Remove the tool after the machine boots. Review your motherboard manual to confirm pin locations. Check connections before proceeding, and only attempt this method if you feel safe working around the hardware. We always recommend care with the power supply and motherboard at each step.
How would someone configure Wake on LAN so they could turn on a computer remotely, and what are the common challenges with network card or bios settings?
To set up Wake on LAN and turn a desktop pc or laptop on from another device, you’ll need to enable the feature in both the bios settings and operating system. Start by booting into the bios and finding Wake on LAN options, making sure the network card supports this. In Windows, check network adapter properties and allow wake signals.
The computer has to stay connected to the power supply and via ethernet cable for reliable signal. Some setups require adjustments to power settings and security in both the machine bios and the router. Unexpected shutdowns or a loose power cable can cause the setup to fail, and not every network card is compatible with wake signals. If you have trouble, review connectors and try a different key or settings combination.
H3 Are there alternative methods for laptop users when turn on pc without power button, considering differences in charger, usb keyboard, and bios compatibility?
For laptops where the power button has failed, there are other ways besides full hardware repair. Plug in the charger and see if charging starts, as some models begin boot automatically when powered. You can also access bios settings by using a usb keyboard if the laptop allows wake using a specific key. Not all laptops support keyboard startup, so compatibility is a concern.
Some manufacturers include an emergency reset or jump connections under the bottom cover. If the laptop does have this feature enabled and the internal battery is charged, you may only need to press a usb keyboard key or use clock battery tricks. Always review your device’s manual for safety instructions and hardware setup.
H3 What risks or damage can occur if you incorrectly short the power switch pins or pull on the wrong cable when trying how to turn on pc without power button?
Shorting power switch pins, if not done carefully, can result in hardware damage. If the screwdriver or tool contacts other pins, it could send an unwanted signal and cause the computer to shut off, reset, or harm the motherboard. Pulling the wrong cable while the power supply is still connected may cause a short, sparks, or destroy sensitive components.
Unplug your desktop computer and review the connector layout before proceeding to lower the risk. Do not rush or skip steps—completing each instruction properly increases safety. Turn on pc without power button, pause and check settings before testing other methods, as improper handling can break your machine or the boot sequence.
How do advanced users install smart hardware or use bios features so a desktop or machine starts after a shutdown or when using a smart outlet method?
Advanced users can set up machines for alternative startup beyond the classic power button. In bios settings, there are options under power management to enable “Restore on AC Power Loss” or similar, which starts the computer when the power supply comes back after being switched off or after a smart outlet is triggered. Some users install relays on the motherboard power pins, allowing remote control or signal by app.
This method works well in professional setups where machines must boot after every shutdown or reset. Always review your hardware compatibility, install devices securely, and make sure settings are correctly enabled for each feature. Missteps in cable connection or incorrect settings can cause trouble in the boot or security features.
