How to Reset Bios Without Display?

Have you ever encountered a situation where your computer is not working properly, and you suspect that the problem is with the BIOS?

If yes, then you might want to reset the BIOS to its default settings.

Resetting BIOS without display can be a tricky task. In this article, we will discuss various methods to reset BIOS without display.

What is BIOS?

Before we dive into the details of resetting BIOS, let’s first understand what BIOS is. BIOS (Basic Input/Output System) is firmware that is embedded in a small memory chip on the motherboard of a computer.

It is responsible for initializing hardware components during the boot-up process and providing runtime services for operating systems and applications.

Why Reset BIOS?

There can be several reasons to reset BIOS. Some of the common reasons include:

• Resolving hardware issues
• Fixing boot-up problems
• Recovering from a failed BIOS update
• Restoring BIOS to its default settings

How to Reset BIOS?

There are three methods to reset BIOS without display. Let’s discuss each method in detail.

Method 1: Clear CMOS Using Jumper

The first method involves clearing the CMOS (Complementary Metal-Oxide-Semiconductor) using a jumper on the motherboard. Follow these steps:

1. Turn off your computer and unplug it from the power source.
2. Open the computer case and locate the CMOS jumper on the motherboard. It is usually near the BIOS chip and labeled as “CLR_CMOS” or “CLRTC.”
3. Move the jumper from its current position to the “Clear” or “Reset” position. Refer to the motherboard manual for the exact position.
4. Wait for a few seconds and then move the jumper back to its original position.
5. Close the computer case and plug in the power cord.
6. Turn on your computer and check if BIOS has been reset.

Method 2: Remove CMOS Battery

The second method involves removing the CMOS battery from the motherboard. Follow these steps:

1. Turn off your computer and unplug it from the power source.
2. Open the computer case and locate the CMOS battery on the motherboard. It is a small, silver, round battery.
3. Gently remove the CMOS battery from its socket.
4. Wait for a few minutes and then reinsert the CMOS battery back into its socket.
5. Close the computer case and plug in the power cord.
6. Turn on your computer and check if BIOS has been reset.

Method 3: Use BIOS Key Combination

The third method involves using a BIOS key combination to reset BIOS. Follow these steps:

1. Turn off your computer and unplug it from the power source.
2. Press and hold the BIOS key combination. The key combination varies depending on the motherboard manufacturer. Refer to the motherboard manual for the exact key combination.
3. While holding the key combination, plug in the power cord and turn on your computer.
4. Release the key combination when you see the BIOS screen.
5. Navigate to the “Reset to Default” or “Load Optimized Defaults” option using the arrow keys.
6. Press the Enter key to reset BIOS to its default settings.

1. Shut down the computer and unplug the power cord. This ensures the computer is completely powered off.
2. Remove the CMOS battery. This is a small round battery located on the motherboard, typically marked as a CMOS battery. Removing this will clear the BIOS settings.
3. Press and hold the power button for 10-15 seconds to drain any residual power from the system.
4. Replace the CMOS battery and reconnect all cables. Plug the power cord back in.
5. Turn the computer back on. The BIOS will now be reset to default factory settings.

Alternatively, if you have access to a PS/2 keyboard or USB keyboard, you can reset the BIOS by:

1. Entering the BIOS settings during startup (by pressing Delete or F2 depending on the motherboard).
2. Navigating to the main BIOS menu.
3. Selecting the “Load Optimized Defaults” or “Load Setup Defaults” option. This will confirm resetting the BIOS to factory defaults.
4. Saving and exiting the BIOS setup. The BIOS reset will now be complete.

Troubleshooting Tips

If you are unable to reset BIOS using any of the above methods, try these troubleshooting tips:

• Check if the motherboard supports hardware reset.
• Update the BIOS firmware using a USB flash drive.
• Contact the motherboard manufacturer for assistance.

What are some common BIOS settings I should check after resetting?

Here are some common BIOS settings you should check after resetting the BIOS:

Boot Order – Make sure your preferred boot devices, like your HDD or SSD, are at the top of the boot order list.

CPU settings – Check that your CPU is detected correctly, the core ratio/frequency/voltage matches your CPU specification, and multi-threading is enabled (if applicable).

Fan settings – Confirm the fan speed settings for your system and CPU fans are appropriate. This can often be set to “Auto” by default.

Memory settings – Ensure your RAM is detected correctly at its proper speed, timing, and capacity. You may need to enable XMP/DOCP to run RAM at advertised speeds.

Power Management – Check that features like Cool’n’Quiet, C-states, and ErP are set how you prefer for power efficiency and performance.

Virtualization – Confirm virtualization extensions like AMD-V and VT-x are enabled if needed to run virtual machines.

USB settings – Check that USB configurations like legacy support and high-speed modes are set correctly.

Secure Boot – Ensure secure boot is enabled/disabled as needed. This is required to boot some operating systems.

SATA Configuration – Confirm your SATA mode and drive configuration matches your storage setup and needs (AHCI, RAID, etc.).

Integrated peripherals – Make sure settings for LAN, audio, and other onboard devices are set how you prefer.

FAQs

Q1. Will resetting BIOS erase my data?

No, resetting BIOS will not erase your data. It only resets the BIOS settings to their default values.

Q2. How often should I reset BIOS?

You should only reset BIOS when necessary, such as when you encounter hardware issues or boot-up problems.

Q3. Can I reset BIOS using the software?

No, you cannot reset BIOS using the software. You need to use one of the hardware methods mentioned above.
