Error: The non-volatile system UEFI variable storage is
nearly full.
Note:
This error indicates that the operating system or
programs cannot create, modify, or delete data in the
non-volatile system UEFI variable storage due to
insufficient storage space after POST.
The non-volatile system UEFI variable storage is used by
the UEFI BIOS and by the operating system or programs.
This error occurs when the operating system or programs
store large amounts of data in the variable storage. All
data needed for POST, such as UEFI BIOS setup settings,
chipset, or platform configuration data, are stored in a
separate UEFI variable storage.
Press F1 after the error message is displayed to enter the
UEFI BIOS menu. A dialog asks for confirmation to clean
up the storage. If you select “Yes”, all data that were
created by the operating system or programs will be
deleted except global variables defined by the Unified
Extensible Firmware Interface Specification. If you select
“No”, all data will be kept, but the operating system or
programs will not be able to create, modify, or delete data
in the storage.
If this error happens at a service center, Lenovo
authorized service personnel will clean up the non-volatile
system UEFI variable storage using the preceding
solution.
