How To Turn On PC Motherboard Without Power Button

Short-circuit power pins on the front panel header to turn on PC motherboard without power button.

Why would you want to turn your PC motherboard without using the main power button? The answer to this is pretty simple. Many PC builders like to check whether or not their PC building has been successful or if they have made any mistakes somewhere. Before you just wind up everything and close the case of your PC, how about checking whether the PC will work or not beforehand? Give a read on how to turn on a PC motherboard without a power button.


Key Takeaways
  • Short-circuiting the motherboard pins to switch it on should be a temporary method and only be used for troubleshooting purposes or in emergencies.
  • It is a convenient way for emergency access and troubleshooting but it is not a permanent solution and can cause potential damage to your system.
  • If your PC isn’t getting started, then you need to check the connections, power cables, and testing components, or reset the CMOS battery as a troubleshooting method.
  • Take necessary precautions before touching any of your PC components to prevent damage from static electricity, such as using an ESD mat, anti-static wrist strap, or touching a grounded metal object.

Preparation

Grab a screwdriver that is flat-headed, switch off the power outlet for a while and ground yourself for your PC’s safety. Open the case of your PC if it is closed and after that switch on the power outlet.

Ground Yourself

Whenever you start working with a PC’s internal parts always go for precautionary measures first. You need to get rid of ESD before touching any component of your PC as ESD is very harmful and it can damage expensive components. You can use an anti-static wristband before starting the procedure or an ESD mat. For a detailed guide on this, please read our article How to ground yourself when building a PC.

Locate Pins

You need to find the front panel header because the pins of the power button are on this header. Inspect the motherboard and find it physically. For your ease, these headers have labels on them. And for the front panel header, the label you need to look for could be any out of F_Panel, JFP1, or FP1. 

Usually, motherboards consist of a 10-pin front panel header. However, some motherboards have a 20-pin front panel header. If you are unable to identify the front panel header, please read the motherboard’s user manual.

After you have found the panel, you need to look more closely and find where the 2 pins are for power. Again the labels will help you. Find the label +PW- and those two pins will be your power pins.

Short Circuit Pins

Be sure that you have located the pins correctly because short-circuiting the wrong pins will lead you to a dead motherboard. How to short circuit? Well, we got you here too. You take a screwdriver and connect both pins, and your PC will turn on.

Now that your PC has turned on, do not touch any other part of your motherboard at all. This will be dangerous for you. Make sure that kids are not around.

WARNING: Use this method temporarily or in emergencies. It’s not a permanent replacement for the power button. If your power button isn’t working, consider getting it fixed by a professional technician or go through our guide How To Connect Power Button To Motherboard.

What If The PC Isn’t Turning On? 

If your PC isn’t turning on after short-circuiting the pins to turn on the motherboard, there are a few steps you can take to troubleshoot the issue:

  • Make sure all connections are correctly placed. This involves inspecting the power supply connections to the motherboard, the CPU power connector, RAM modules, and any other required components. Loose connections may prevent the PC from turning on.
  • Try resetting the CMOS by removing the CMOS battery from the motherboard for a while and then reinserting it. This step resets BIOS settings to their defaults and may address any setup difficulties.
  • Visually check the motherboard for physical damage, such as burned components or blown capacitors. If you see any damage, it might signal a hardware problem that requires expert repair or replacement.
  • If possible, test individual components such as the power supply, RAM, and CPU in another compatible system to determine if they are functioning correctly. This step helps identify any faulty components that may be causing the problem.
Tip: Test the PC in a different power outlet to rule out any issues with the electrical socket.
