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 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
ThinkPad Setup. A dialog asks the user for confirmation
to clean up the storage. If the user selects "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 the
user selects "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.
