What Is BIOS and Why Does Your Mini PC Need a Reset?
The BIOS is the first software that runs when you power on your Mini PC. It initializes your hardware components and hands control over to your operating system. Without a properly functioning BIOS, your system simply will not start.
What Does the BIOS Do?
The BIOS performs several critical tasks every time you turn on your computer. It runs a Power-On Self-Test, commonly called the POST test, to check your hardware. It then initializes your CPU, memory, and storage devices. Finally, it hands control to your operating system. All of this happens in seconds, and you never even notice it is happening.
Your BIOS also stores important configuration settings. These include your boot sequence, CPU fan speeds, voltage levels, and security options. When these settings become corrupted or misconfigured, your Mini PC can experience serious problems. That is when you need to know how to reset BIOS on Mini PC.
Why Do BIOS Settings Get Corrupted?
Several factors can corrupt your BIOS settings. A sudden power outage during a firmware update is one of the most common causes. Viruses and malware can also tamper with BIOS firmware. Sometimes, overclocking your system too aggressively causes instability. In rare cases, a failing motherboard can cause persistent BIOS errors. Regardless of the cause, the fix is often the same: reset the BIOS.
Common Signs That Your Mini PC BIOS Needs Resetting
Not sure if your Mini PC needs a BIOS reset? Look for these telltale signs. Recognizing them early can save you hours of troubleshooting.
- System Won’t Boot: If your Mini PC powers on but displays nothing on screen, a corrupted BIOS could be the culprit.

- Hardware Not Recognized: Your storage drives, RAM, or USB devices are not detected by the system after startup.
- BIOS Password Forgotten: You set a BIOS password and cannot remember it. A reset clears this lock.
- Overheating or Fan Errors: Incorrect fan speed settings in the BIOS can cause your system to overheat.
- Boot Order Changed: Your system tries to boot from the wrong device, like a USB drive instead of your hard drive.
If you notice any of these symptoms, do not panic. Most BIOS issues are fixable with a simple reset. And once you learn how to handle this, you will feel much more confident managing your Mini PC.
How to Reset BIOS on Mini PC Using the CMOS Battery Method
The CMOS battery method is the most popular way to reset BIOS. It works on most Mini PC models and requires no special tools. The CMOS battery keeps your BIOS settings alive when the computer is powered off. By removing it, you clear all stored settings and return the BIOS to its factory defaults.
What You Will Need
Before you start, gather these items:
- A small Phillips-head screwdriver
- An anti-static wrist strap (optional but recommended)
- A replacement CR2032 battery (the same type as the one you remove)
- A clean, dry workspace
Step-by-Step Instructions
Step 1: Power Off Your Mini PC. Shut down your system completely. Do not just put it to sleep. Turn it off and unplug the power cable. If your Mini PC has a battery backup, disconnect that too.
Step 2: Unplug All Peripherals. Remove your mouse, keyboard, USB drives, and any other external devices. This prevents any accidental damage during the process.
Step 3: Open the Case. Use your screwdriver to remove the screws on the Mini PC chassis. Carefully lift off the side panel. Place the screws somewhere safe so you do not lose them.
Step 4: Locate the CMOS Battery. Look for a small, round silver battery on the motherboard. It is usually a CR2032 coin cell battery. It may be held in place by a small metal clip.
Step 5: Remove the Battery. Gently pry the battery out of its slot using your finger or a plastic tool. Do not use metal tools, as they can damage the motherboard. Wait at least five minutes before proceeding.
Step 6: Reinsert the Battery. Place the CMOS battery back into its slot. Make sure it clicks into place securely. Replace the side panel and screw it back on.
Step 7: Reconnect Power and Test. Plug in your power cable and peripherals. Power on your Mini PC. The BIOS should now be reset to factory defaults. You may need to reconfigure some settings, such as the boot order.
Important Tips for the CMOS Method
Always handle the motherboard with care. Avoid touching exposed components directly. If you have an anti-static wrist strap, wear it. Ground yourself by touching a metal part of the case before reaching inside. Keep your workspace clean and well-lit. Taking these simple precautions prevents accidental damage.
After the reset, if you notice your external mouse is not responding properly, you might need to reset the mouse on a laptop as well, since BIOS resets can sometimes affect peripheral initialization.
How to Reset BIOS on Mini PC Using the Jumper Method
The jumper method is another effective way to reset your BIOS. It uses a small physical switch on the motherboard to clear CMOS settings. This method is faster than the battery approach and works well on most Mini PC motherboards.
Understanding the CMOS Jumper
A CMOS jumper is a tiny plastic connector that sits over two or three pins on the motherboard. When the jumper is in its default position, the CMOS settings are preserved. When you move it to the clear position, the BIOS resets. Not all motherboards have a dedicated CMOS jumper, but most Mini PCs do.
Step-by-Step Instructions
Step 1: Power Off and Unplug. Start by shutting down your Mini PC completely and disconnecting all power sources.
Step 2: Open the Case. Remove the screws and carefully take off the side panel. Refer to your Mini PC manual if you are unsure how to open it.
Step 3: Find the CMOS Jumper. Look for a group of three pins near the CMOS battery on the motherboard. There should be a small plastic jumper cap sitting on two of the pins. Check your motherboard manual to confirm the exact location.
Step 4: Move the Jumper. Use your finger or a small flat tool to move the jumper cap from its current position to the clear pins. This is usually pins 1 and 2, or labeled CLR_CMOS. Leave it in this position for about ten seconds.
Step 5: Return the Jumper. Move the jumper cap back to its original position. This is critical. If you leave it in the clear position, your BIOS will not initialize properly.
Step 6: Close the Case and Test. Replace the side panel, reconnect all cables, and power on your Mini PC. The BIOS should now be reset.
Jumper Method vs. CMOS Battery Method
Both methods achieve the same result. The jumper method is slightly faster and does not require opening the case for long periods. However, the CMOS battery method is more universal and works on systems without a dedicated jumper. Choose the method that feels most comfortable for you.
How to Reset BIOS on Mini PC Using Software and Keyboard Shortcuts
Not all BIOS resets require opening your Mini PC. In some cases, you can reset the BIOS from within the system or using keyboard shortcuts during startup. These software-based methods are convenient and do not involve any hardware work.
