4 Ways to Reset BIOS Password

Getting into the BIOS settings is crucial if you want to modify the boot priority, overclock the  CPU or troubleshoot system-related issues. However, if a password is set and you are unaware of it, this can be quite a hassle when you want to boot into the BIOS or even the operating system. 

If you do know the administrator password, you can reset it by entering the BIOS settings. You can also clear out the BIOS password by clearing the CMOS battery. 

Before going into the password reset process, it is worth knowing the two different password types you can set on the BIOS.  

  • Administrator Password: If this password is set, users have to enter it every time they try to enter the BIOS. It restricts unauthorized access or modification of the BIOS settings. 
  • User Password: You will be asked for the user password before the operating system loads up. This password is also referred to as the System password on some devices. The operating system will not boot up unless you provide the correct user password.

Reset the Password From BIOS

If you remember the Administrator password for the BIOS, you can clear or reset it from the BIOS settings.

  1. Restart the computer and press the specific BIOS key for your device when you see the manufacturer logo. The key to enter the BIOS could vary with the manufacturer but it is usually F1, F2, F10, F12, or DEL.
  2. It will ask you for the administrative or user password to access the BIOS. Enter the password.
    Admin password in BIOS
  3. Now, find the section for configuring the BIOS password.
    BIOS settings for password
  4. Navigate to the section and hit enter, then enter the current password. 
    Enter current bios password
  5. When asked for a new password, leave the field empty and select Ok. Do the same for both the Admin and the User Password.
     clear BIOS password
  6. Save and Exit from the BIOS. 
  7. This will clear out the BIOS password. You will now have access to the BIOS without having to enter a password.  

Using Clear CMOS Button

Some new higher-end motherboards come with a CMOS reset button that can revert the BIOS configurations to their factory default. This button is usually located in the back I/O panel of the motherboard. The name of this button can vary with the manufacturer.  You may find it labeled as “ClearCMOS”, “Flash” or “Reset CMOS.” 

  1. Shut down the computer and disconnect all the cables attached to the computer’s case.
  2. Find the CMOS reset button on the back of the case. 
    clear cmos button
  3. Press and hold the button for 15-20 seconds. 
  4. Put the computer back in place and then turn it on.
  5. Using your device-specific BIOS key try to boot into BIOS. See if it asks you for the password. 

If you did not find a CMOS reset button on your computer, you can also use the BIOS jumper to reset the password. The jumper is a series of metal pins located in the motherboard. These jumpers are responsible for opening, restricting, or bypassing an electrical circuit. 

CMOS jumper is a three-pin conductor located in the motherboard near the CMOS battery.  To reset the BIOS password you need to shift the CMOS jumper from its default position. 

  1. Turn off the computer and disconnect all the cables and peripherals connected to it. Now press and hold the power button for about 20 seconds. This will drain the excess power stored in the motherboard. 
  2. Open the side panel of the CPU to gain access to the motherboard. 
  3. Locate the CMOS Jumper. It must be labeled CLRPWDRESETCLRTCCLEARCLEAR CMOS, or similar phrases. 
  4. You will see three pins in the Jumper with the default configuration 1-2.
    BIOS jumper original position 
  5. To reset the BIOS, shift the jumper to position 2-3.}
     shifting jumper to clear the bios password
  6. Wait for a while and move the jumper back to its default position. 
  7. Finally, reassemble the computer, turn on the computer and try to boot into the BIOS. You will not be asked for any passwords 

On the laptops, you will not find the jumpers or Clear CMOS button. Reseating the CMOS battery becomes the only option in that case. The CMOS battery is responsible for retaining the BIOS configurations including its password. When you remove the CMOS battery, there will be nothing to power up the BIOS firmware, and the configurations including the password revert to their factory default.  

For the Laptops, you need to open the back panel to get access to the motherboard and then the CMOS battery. 

Some Laptops come with a soldered CMOS battery which makes it difficult to reset or replace them. In that case, visit the service center for resolving the issue.

Does Your Desktop Have Wi-Fi? Here’s How to Find Out

The easiest way to tell if your desktop has Wi-Fi is by checking the back side of your chassis for Wi-Fi support. Your desktop might have a built-in Wi-Fi module, a PCIe Wi-Fi adapter, or a USB Wi-Fi receiver installed. Alternatively, you may find a port labeled “Wi-Fi” on the back of the computer.

But there are cases where the Wi-Fi adapter or its driver is disabled in your system. This will restrict the OS from accessing Wi-Fi, leading you to think that the desktop does not have Wi-Fi. So you need to perform several steps to determine if your desktop has Wi-Fi.

Table of Contents

Check Motherboard Manual

Your motherboard user manual contains every detail about the motherboard, its supported component, and how to connect each component. Using the manual, you can check if your motherboard supports Wi-Fi. 

Check System Tray Icon

Check Windows Settings

Network and internet settings in Windows allow you to access and change any network-related settings. This includes Wi-Fi as well. If you do not see Wi-Fi listed on the Network and Internet settings, your desktop does not support Wi-Fi.

  1. Press the Windows + I key to open Settings.
  2. On the left panel click Network & internet.
    netword and internet check wi-fi

Now, on the left panel, you will see a list of network settings. If the list contains Wi-Fi, your desktop has Wi-Fi. Enable it to connect to a network wirelessly.

You will not see Wi-Fi in Windows settings if it is disabled from the Control Panel. In that case, you need to check Network Connections as well.

Check Network Connections

Network connections contain the list of all your system’s built-in or connected network devices. Besides this, you can also disable/enable each device driver, manage its properties and diagnose the device. Using Network connections, you can determine whether your system has Wi-Fi.

  1. Press the Windows + R key to open Run.
  2. Type ncpa.cpl and press Enter to open the Network Connections window.
    open network connections does my pc have wifi
  3. Here, check if Wi-Fi is listed.
    check network connections

To ensure this is not the case, we recommend you check if the device is removed from the Device Manager or disabled from the BIOS.

Check Device Manager

When uninstalling a driver using Device Manager, the OS will not acknowledge the device. Even if the device is connected, you cannot access its functionalities. The same goes for the Wi-Fi driver. 

You cannot access Wi-Fi settings if the Wi-Fi driver is uninstalled or not installed at all.

  1. Press the Windows + X key and select Device Manager.
    open device manager desktop wifi
  2. Right-click on the top of the list where you see the Desktop name.
  3. Click on Scan for hardware changes. By doing this, the Device Manager will automatically check the system for drivers and install them.

  4. Now, Check Network connections to see if you see Wi-Fi.

Check BIOS

BIOS, or the Basic Input Output System, allows users to access and change the settings related to hardware connected to the motherboard. You can also enable and disable Wireless LAN or WLAN using the BIOS. If disabled, your OS will not detect the Wi-Fi adapter.

You need to enable WLAN in the BIOS to ensure that the OS uses Wi-Fi.

  1. Repeatedly press the BIOS key during startup to enter the system BIOS. The BIOS key could be any of the function keys or the delete key.
  2. Navigate and find settings such as, WLANOnBoard WLan Controller or WLAN enable and Enable it.
    disable onboard wi-fi
  3. Save and exit the BIOS.
  4. Boot into the OS and check if the Network Connections displays Wi-Fi.

How To Reset Ethernet Adapter

Resetting the Ethernet adapter usually involves disabling and re-enabling it. Disabling the adapter unloads the device driver and sets the interface state as Disconnected. It also leads to other device-specific procedures like clearing the ARP table entries.

This is why a basic adapter reset fixes so many networking errors in Windows. If simply restarting the adapter doesn’t help, you can also try a complete reset by resetting and reinstalling the networking components.

Performing a basic reset on your Ethernet adapter will solve various errors (e.g., network protocols missing). Let’s look at some other cases though.

Instead of resetting the Ethernet adapter, disabling the wireless adapter helps with the Err_Network_Change problem. Disabling the Virtual WiFi Miniport Adapter can fix DNS errors. Disabling all adapters except the Ethernet adapter can solve the Unidentified Network error.

The point here is that resetting the Ethernet adapter will fix some problems, but resetting or disabling the rest will be more effective for others. Please keep this in mind when troubleshooting your current problem.

    enable-net-adapter-ethernet

When a basic reset isn’t enough, you’ll need to resort to a thorough reset to fix any problems with your Ethernet adapter.

Step 1: Reset Network Components

To start, we’ll reset the Winsock catalog to a clean state. Then, we’ll reset the TCP/IP parameters, which does the same thing as removing and reinstalling TCP/IP would.

  1. Press Win + R, type cmd, and press Ctrl + Shift + Enter.
  2. Execute the following commands:
    Netsh winsock reset
    Netsh int ip reset
    netsh-winsock-reset-int-ip-reset
  3. Restart your PC and check if your problem is resolved. If not, check the next step.

Step 2: Fix Ethernet Driver

A corrupted Ethernet driver falls among the most common reasons for networking problems. Sometimes, simply updating to the latest driver will fix the problem. In other cases, the latest driver might be the problem and you’ll need to revert to an older stable version.

  1. Press Win + X and select Device Manager.https://836cef854dc2b940ae0605013c696649.safeframe.googlesyndication.com/safeframe/1-0-40/html/container.html
  2. Expand the Network Adapters section.
  3. Right-click your Ethernet adapter and select Update Driver.
    update-ethernet-controller-driver
  4. Select Search automatically for drivers and follow the on-screen instructions.
    ethernet-controller-update-driver
  5. If auto-update doesn’t help, download the driver from your device manufacturer’s site. 
  6. If they provide a driver installer, use that. But if they provide .inf files, open Device Manager again.
  7. Follow Steps 2-3 and select Browse my computer for drivers.
  8. Select Browse and locate the folder containing the driver files.
    browse-ethernet-driverhttps://836cef854dc2b940ae0605013c696649.safeframe.googlesyndication.com/safeframe/1-0-40/html/container.html
  9. Press Next > Ok and follow the on-screen instructions to update the network driver.

As stated, updating to the latest driver will generally fix networking problems. But sometimes, you may need to try out different driver versions until you find a compatible one.

What If Resetting Doesn’t Work?

In rare cases, the adapter keeps getting disabled automatically, or users are unable to turn it back on. If this is happening to you, here’s what we recommend:

  1. Press Win + X and select Device Manager.
  2. In the Network Adapters section, right-click your Ethernet adapter and select Properties.
    ethernet-controller-properties
  3. In the Power Management tab, ensure the Allow the computer to turn off the device to save power option is not enabled.
    ethernet-controller-power-management-properties
  4. If you made the change just now, press Ok to apply it.

Aside from this, we’ve mostly seen this problem occur after updating or upgrading Windows. As such, updating to a newer patched version, or reverting to an older stable one is the best course of action here. Installing a compatible driver directly from your device manufacturer, as detailed in the previous section, can also help.
