To reset the BIOS password on a Lenovo ThinkCentre M720q, you must use the physical Clear CMOS (Maintenance) jumper located on the motherboard. Modern Lenovo systems often store supervisor passwords in non-volatile memory, so simply removing the CMOS battery may not be effective. Step-by-Step Reset Procedure
Preparation: Turn off the computer and disconnect all power cords and cables. Open the chassis by removing the rear screw and sliding the cover forward.
Locate the Jumper: Find the Clear CMOS/Recovery jumper (often labeled as JP35 or near the Wi-Fi card area) on the system board.
Move the Jumper: By default, the jumper is on pins 1 and 2 (or 5 and 6 on some blocks). Move it to the maintenance position, pins 2 and 3 (or 2 and 4).
Power On: Reconnect the power cord and turn on the computer. Leave it on for about 10–30 seconds. You may hear a series of beeps indicating the system is in maintenance mode.
Shut Down: Turn off the computer by holding the power button for five seconds and disconnect the power cord again.
Restore Jumper: Move the jumper back to its original standard position (pins 1 and 2).
Finalize: Replace the cover, reconnect cables, and power on. Press F1 during the Lenovo splash screen to enter the BIOS. The password should now be cleared or reset to default.

To reset the BIOS password on a Lenovo ThinkCentre M720q , you must use the physical Clear CMOS (Maintenance) jumper
located on the motherboard. This process will clear lost or forgotten power-on and supervisor passwords, though it does apply to hard disk passwords. Preparation and Safety
Before starting, ensure you have a clean workspace and a Phillips-head screwdriver. Power Down
: Turn off the computer and disconnect all cables, including the power adapter. Open the Chassis
: Remove the single screw at the rear and slide the top cover forward to expose the internal components. Static Safety
: Touch a grounded metal object to discharge static electricity before touching any internal parts. Step-by-Step Reset Procedure The M720q uses a specific jumper block, often labeled
, located near the Wi-Fi antenna or corner of the motherboard. Locate the Jumper : Find the Clear CMOS / Maintenance jumper . In its default "Normal" position, the jumper connects pins 6 and 5 (or pins 1 and 2 on some variants). Move to Maintenance Position Disconnect the AC adapter.
Move the jumper from its standard position to the maintenance position (connecting pins 2 and 4
Some users found removing the RAM on the backside during this process critical for a full reset. Power On for Reset Connect the power cord and turn the computer on.
Wait for a series of beeps (typically 2-5 sets). This indicates the BIOS is in maintenance mode and clearing the settings. Let it run for approximately 10 to 30 seconds after the beeps. Finalize the Reset
Turn off the computer by holding the power button for 5 seconds. Disconnect the power cord again. Move the jumper back
to its original standard position (connecting pins 6 and 5 or 1 and 2). Reassemble and Verify Replace the cover and reconnect your peripherals. Power on and repeatedly tap to enter the BIOS Setup.
The password prompt should no longer appear, allowing you to configure new security settings. Alternative: CMOS Battery Method
If the jumper method is inaccessible, you can try a "hard" CMOS reset by removing the internal battery. Remove the CMOS Battery To reset the BIOS password on a Lenovo

Lenovo ThinkCentre M720q BIOS Password Reset: A Step-by-Step Guide
Are you locked out of your Lenovo ThinkCentre M720q due to a forgotten BIOS password? Don't worry, we've got you covered. In this blog post, we'll walk you through the process of resetting the BIOS password on your Lenovo ThinkCentre M720q.
What is a BIOS password?
The BIOS password, also known as the UEFI firmware password, is a security feature that protects your computer from unauthorized access. It's a password that's stored in the BIOS (Basic Input/Output System) chip on your motherboard, and it's used to prevent others from accessing your computer's settings or booting from unauthorized devices.
Why do I need to reset the BIOS password?
If you've forgotten your BIOS password, you won't be able to access your computer's settings or make changes to the BIOS. This can be frustrating, especially if you need to make changes to the boot order or disable secure boot. Resetting the BIOS password will allow you to regain access to your computer's settings and make the necessary changes.
Method 1: Resetting the BIOS password using the built-in reset jumper
The Lenovo ThinkCentre M720q has a built-in reset jumper that allows you to reset the BIOS password. Here's how to do it:
Method 2: Resetting the BIOS password using a third-party tool
If you're not comfortable with opening up your computer's case or can't find the reset jumper, you can use a third-party tool to reset the BIOS password. One popular tool is Hiren's BootCD.
Method 3: Contacting Lenovo support
If you're not comfortable with trying the above methods or if they don't work for you, you can contact Lenovo support for assistance. They may be able to provide you with a BIOS password reset procedure or offer additional guidance.
Conclusion
Resetting the BIOS password on your Lenovo ThinkCentre M720q is a relatively straightforward process. By using the built-in reset jumper or a third-party tool, you can regain access to your computer's settings and make the necessary changes. If you're still having trouble, don't hesitate to contact Lenovo support for assistance. Power-on Password (POP) : This password is required

Additional resources
Since physically resetting the BIOS password on the Lenovo ThinkCentre M720q typically requires contacting Lenovo support (due to security certifiers like TPM 2.0), the most effective "feature" to create is a management software utility that handles the challenge-response authentication system built into the hardware.
Here is a design specification for a hypothetical software feature to address this need.
Warning: This method involves opening your computer. Ensure you're comfortable with this and that you're aware of static protection measures.
Power off your ThinkCentre M720q and unplug it from the power source.
Open the side panel of your computer. Typically, you'll need to remove a few screws at the back.
Locate the CMOS battery on your motherboard. It's usually a small, silver, coin-like battery.
Remove the CMOS battery. You'll need to unscrew or gently pry it out, depending on its holder.
Wait for about 30 seconds to a minute. This allows any residual power to drain and effectively clears the CMOS.
Replace the CMOS battery and reassemble your computer.
Power on your computer. The BIOS settings, including the password, should now be reset to their default state.
If the password only locks entering setup (F1), but the PC boots to Windows, you can sometimes issue a command to clear the BIOS to defaults:
powershell "Get-WmiObject -Class Win32_BIOS -Namespace root\cimv2 | Invoke-WmiMethod -Name SetPowerState -ArgumentList 12"
Note: This resets settings, but rarely clears a master password.If your M720q is a business-critical machine (microserver, POS system, medical device) and you cannot risk bricking it, call a professional.
Power on the computer and immediately start pressing the F1 key (or Del key, depending on your specific model) repeatedly to enter the BIOS settings. For ThinkCentre models, F1 is commonly used.
Navigate through the BIOS menu to find the "Security" or similar tab.
Look for "Supervisor Password" or "BIOS Password" settings.
If you can see the current password field, try leaving it blank and pressing Enter, then confirm by pressing Enter again. Sometimes, an empty password can be accepted.
If there's an option to disable the password, do so. However, if you can't see this option or the password field isn't accessible due to the set password, proceed to the next method.
