• Message: Error: The System UEFI Variable Storage is nearly full.
Note: This error indicates that the operating system or applications 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
applications. This error occurs when the operating system or applications 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: Enter ThinkPad Tablet Setup after the error message is displayed. 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 applications are deleted except global variables defined by the Unified Extensible Firmware
Interface Specification. If the user selects "No", all data is kept, but the operating system or applications
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 above solution.
