Solution
The computer turned off because the battery power is low. Connect the
ac power adapter to the computer and charge the batteries.
The system configuration change has failed. Confirm the operation and
try again.
This message is displayed when you enter a wrong supervisor password
more than three times. Confirm the supervisor password and try again.
The date or the time is not set in the computer. Enter the BIOS menu and
set the date and time.
The wireless network card is not supported on this computer. Replace
with a supported wireless network card.
Turn off and remove all but the reader that you set up within your main
operating system.
The storage drive is not working. Reinstall the storage drive. If the
problem still exists, replace the storage drive.
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 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.
