Lenovo ThinkPad T540p BIOS Update Utility 2.21 Description

This package updates the UEFI BIOS (including system program and Embedded Controller program) stored in the ThinkPad computer to fix problems, add new functions, or expand functions. This program is language independent and can be used with any language system.

Fixes:

- Added support for the UEFI DriverOrder feature.
- Updated the Diagnostics module to version 2.03.00.
- Fixed an issue where UEFI KeyShiftState was not correctly returned for some keys.
- Fixed an issue where the PCI LAN device was excluded after loading Setup defaults through WMI.
- Fixed an issue where SMBIOS type 15 structure (System Event Log) was incorrect.
- Fixed an issue that did not keep Fn Key Lock state after resuming normal operation from Intel Rapid Storage Technology.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
