Protect data against power loss
NVMe (Non-Volatile Memory express) M.2 solid-state drive features the Lenovo-unique PLP (Power Loss
Protection) function to avoid data loss or damage.
If your computer is not responding and you might have to shut down your computer by pressing and holding
the power button for several seconds. In this case, the PLP function enables your computer data to be saved
timely. However, there is no guarantee that all data is saved in any situation.
To check the type of your M.2 solid-state drive:
Step 1.
Restart the computer. When the logo screen is displayed, press F10 to enter the Lenovo
diagnostics window.
On the TOOLS tab, select SYSTEM INFORMATION ➙ STORAGE using the arrow keys.
Step 2.
Step 3.
Locate the Device Type section to check the information.
UEFI BIOS passwords
You can set passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/Output System) to
strengthen the security of your computer.
Password types
You can set a power-on password, supervisor password, system management password, or NVMe
password in UEFI BIOS to prevent unauthorized access to your computer.
However, you are not prompted to enter any UEFI BIOS password when your computer resumes from sleep
mode.
Power-on password
If you set a power-on password, a window is displayed on the screen when you turn on the computer. Enter
the correct password to use the computer.
Supervisor password
The supervisor password protects the system information stored in UEFI BIOS. When entering the UEFI
BIOS menu, enter the correct supervisor password in the window prompted. You also can press Enter to
skip the password prompt. However, you cannot change most of the system configuration options in UEFI
BIOS.
If you have set both the supervisor password and power-on password, you can use the supervisor password
to access your computer when you turn it on. The supervisor password overrides the power-on password.
NVMe passwords
The NVMe password prevents unauthorized access to the data on the storage drive. When an NVMe
password is set, you are prompted to type a correct password each time you try to access the storage drive.
• Single Password
When a Single NVMe password is set, the user must enter the user NVMe password to access files and
applications on the storage drive.
• Dual Password (User + Admin)
