Here’s what else to consider
If your computer is experiencing problems such as boot failures, incorrect date and time, or incorrect hardware settings, you may need to reset the BIOS settings. BIOS stands for Basic Input Output System, and it is a firmware that controls the low-level functions of your motherboard, such as the communication between the CPU, RAM, and disk drives. Resetting the BIOS settings can help you troubleshoot and fix some common hardware issues, but it can also erase any customizations you have made. In this article, we will show you how to reset the BIOS settings using three different methods: using a jumper, using a battery, or using a software.
Key takeaways from this article
-
Use software reset:
Access the BIOS menu during boot-up by pressing a designated key, usually F2, F10, F12, or Del. In the BIOS setup, select an option like "Load Optimized Defaults" to reset settings without opening the case.
-
Clear CMOS with button:
Some motherboards have a dedicated CMOS reset button. Press this instead of using a jumper or removing the battery. For stubborn issues, reseat your RAM after clearing CMOS to potentially solve faults.

1 Using a jumper
A jumper is a small metal clip that connects two pins on the motherboard. Some motherboards have a jumper that is specifically designed to clear the BIOS settings, usually labeled as CLR_CMOS, CMOS_RST, or something similar. To use this method, you need to turn off your computer, unplug the power cord, and open the case. Then, locate the jumper and move it from its normal position to the clear position, usually indicated by a diagram or a label on the motherboard. Wait for a few seconds, then move the jumper back to its normal position. Close the case, plug the power cord, and turn on your computer. The BIOS settings should be reset to their default values.

Turn off your computer.Access the BIOS:Restart your computer.Immediately press the designated key (usually F2, Del, or Esc) repeatedly as the computer starts. The exact key might vary. Look for a message indicating which key to press during startup.Enter the BIOS Menu: The BIOS interface will appear.Load Factory Defaults:Navigate to the "Load Defaults" or similar.Choose "Load Factory Defaults" or a similar.Confirm the action if prompted.Save and Exit:Save the changes and exit the BIOS. Your computer will restart.If the above steps don't resolve the issue:Check for CMOS Battery: Some PCs have a small, CMOS on the motherboard. Replacing this battery might reset the BIOS. Clear CMOS Jumper: Some motherboards have a CMOS jumper.

The jumper reset method, prevalent in troubleshooting hardware glitches or resetting BIOS settings, involves multiple steps. Initially, identify the jumper, a small connector bridging two motherboard pins, usually labeled CLR_CMOS or CMOS_RST. Post power-off, access the motherboard by opening the computer case. Shift the jumper from its standard position to the clear position, as guided by the motherboard or its manual, and wait for around 5-10 seconds for electrical discharge to clear BIOS settings. Return the jumper to its original position before closing the case, reconnecting power, and rebooting. This method, common with desktop motherboards, diverges from BIOS reset/recovery methods on laptops which don't use a jumper.

It depends on the device Coz each company has different requirements But the most common one in clear CMOS by removing the battery Or you need a special equipment to erase the bios

2 Using a battery
Another way to reset the BIOS settings is to remove the battery that powers the CMOS chip, which stores the BIOS settings. The battery is usually a round silver coin-like device that is attached to the motherboard. To use this method, you need to follow the same steps as the jumper method, except that instead of moving a jumper, you need to carefully remove the battery from its holder. Wait for a few minutes, then reinsert the battery in the same orientation. Close the case, plug the power cord, and turn on your computer. The BIOS settings should be reset to their default values.

Utilizing the battery to reset BIOS settings involves removing the battery powering the CMOS chip, where BIOS settings are stored. Typically resembling a silver coin, the battery is nestled on the motherboard. Similar to the jumper method, power down the computer and access the motherboard by opening the case. Carefully extract the battery from its holder, wait a few minutes to ensure all settings are cleared, then reinsert the battery with correct orientation. Following reassembly and power reconnection, power on the computer. The BIOS settings should revert to default, ready for any necessary reconfigurations. Manufacturer-specific requirements and steps may apply when resetting BIOS via battery removal, ensuring a safe reset process.

3 Using a software
The third method to reset the BIOS settings is to use a software tool that is built into the BIOS itself. This method does not require you to open the case or touch any hardware components, but it may not work if you cannot access the BIOS menu. To use this method, you need to turn on your computer and press the key that enters the BIOS setup, usually F2, F10, F12, or Del. Once you are in the BIOS menu, look for an option that says Load Optimized Defaults, Load Setup Defaults, Reset BIOS Settings, or something similar. Select this option and confirm your choice. Then, save and exit the BIOS menu. The BIOS settings should be reset to their default values.

Initiating this process involves rebooting your computer and pressing the designated key (often F2, F10, F12, or Del) to access the BIOS setup. Within the BIOS menu, navigate to find an option labeled as Load Optimized Defaults, Load Setup Defaults, Reset BIOS Settings, or something similar, depending on the motherboard manufacturer. Selecting this option and confirming your choice initiates the reset, ensuring all settings are reverted to their original state. It's crucial to navigate to the exit menu to save these changes and exit the BIOS, which finalizes the reset procedure, making it ready for new configurations if needed. Admin password maybe required based on configuration to reset.

Many modern motherboards have a CMOS reset button instead of, or in addition to the jumper. If you're resetting the BIOS settings with the aim of clearing a fault, it can also be worth removing and reseating the RAM modules during the CMOS reset process. Computers that have been left powered off for extended periods and fail to POST are an example of where this added step can clear a fault.
