The 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. On very rare occasions, your computer is not responding
and you might have to shut down your computer by pressing and holding
the power button for about seven seconds. In this case, the PLP function
enables key data of your computer 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:
Restart the computer. When the logo screen is displayed, press
F10 to enter the Lenovo diagnostics window.
On the TOOLS tab, select using the arrow keys.
Locate the Device Type section to check
the information.
