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:
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.
