• Message: 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 BIOS setup settings, chipset, or platform
configuration data, are stored in a separate UEFI variable storage.
Solution: 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.
