| Password Type | Description & Management | | :--- | :--- | | | A password required to turn on or wake the computer. Forgetting it is a common but manageable issue. It can often be reset by a service technician if the system board (motherboard) is replaced for a fee. | | Supervisor Password (SVP) | The "master" BIOS password. If forgotten, there is no standard service procedure to reset it ; the motherboard must typically be replaced. It's designed for strict security, so always store this password safely. | | System Management Password (SMP) | Similar to SVP but with configurable authority. It can be set via the BIOS menu or IT management tools. If both SVP and SMP are set, the Supervisor Password takes precedence. | | NVMe Password | Encrypts data on the SSD. Extremely high security: if forgotten and no admin password is available, Lenovo cannot unlock the drive or recover data. Data recovery is impossible without the password. | | Hard Disk Password (HDP) | Legacy password securing SATA hard drives. Operates similarly to an NVMe password but for older drive types. If forgotten without an admin password, data recovery is also impossible. | | User Password | A secondary password that can be set to restrict BIOS entry, functioning with fewer privileges than the Supervisor Password. | Connect the AC adapter
