If you want, I can provide the M720q hardware maintenance manual steps for locating CMOS/jumpers or a checklist for safely removing the drive for data recovery.
Forgetting or losing a BIOS password on a Lenovo ThinkCentre M720q Tiny can lock you out of critical system settings, such as boot order or hardware configuration. Fortunately, you can reset this password using a physical hardware jumper on the motherboard. 1. Locate the CMOS/Recovery Jumper The first step is to access the internal hardware.
Shut Down & Unplug: Power off the computer and disconnect the AC adapter and all other cables.
Open the Case: Remove the single screw at the back of the chassis and slide the top cover forward to remove it.
Find Jumper JP35: Hold the unit so the rear ports are at the top. The Clear CMOS/Recovery jumper is typically a 6-pin block located in the upper-left corner of the motherboard, often near the Wi-Fi antenna or M.2 slot.
Note Default Position: In its standard operating state, the jumper is usually on pins 5 and 6. 2. Move Jumper to Maintenance Mode lenovo thinkcentre m720q bios password reset
Moving the jumper tells the system to clear stored security settings.
Reposition Jumper: Carefully move the jumper from the standard pins (5-6) to the maintenance position (pins 2 and 4).
Critical Tip: Some users report that removing the RAM from the bottom side of the unit during this process is necessary for a successful reset. 3. Clear the Password
Power On: Reconnect the power cable and press the power button. The screen may remain black, but the internal speaker should begin to emit a series of double beeps or a short melody.
Wait for Beeps: Allow the computer to beep for several cycles (roughly 30–60 seconds) to ensure the CMOS has been cleared.
Power Off: Press and hold the power button to shut the system down, then disconnect the AC adapter again. 4. Restore Standard Configuration How do you remove admin password from bios Lenovo m700 tiny

A: Yes, there are third-party tools available that can help you reset the BIOS password on your Lenovo ThinkCentre M720q. However, make sure you download the tool from a reputable source to avoid malware or viruses.
Many corporate refurbished units have standard passwords.
If the short method fails (or you accidentally short the wrong pins and brick the board), you have one final option. and the password will be gone.
Buy a pre-programmed BIOS chip.
When you install the new chip, the system will have a completely clean BIOS with no password. You will need to input the machine's serial number (on the sticker on the case) using a tool like AMIDEWINx64.exe to restore full functionality.
Step 1: Full Disassembly
Step 2: Locate the EC Chip On the M720q motherboard, look for a small, square, flat chip with "IT8528E" or "IT8987" printed on it. This is the Embedded Controller that manages power and security.
Step 3: Find the Security Pins You are looking for pins labeled "KBC" (Keyboard Controller) or "SDA/SCL" near the EC. Based on community schematics for the M720q (IBM Lenovo FRU: 5B20S43790 or similar), you need to short pin 8 (GND) to pin 1 (SDA) of the EC's debug header.
Alternatively, many technicians use the "Southbridge short": Find two tiny resistors labeled R484 and R485 near the CMOS battery connector. Short those two resistors together with tweezers while powering on.
Step 4: The Reset Procedure
If successful, the system will boot directly into the BIOS with a checksum error, and the password will be gone.
