Lenovo ThinkPad T420s BIOS Update CD 1.37 Description

This package provides the ISO image file of UEFI BIOS which is compatible with CD/DVD writing software to create the CD/DVD for the UEFI BIOS update. Hereafter the CD/DVD for the UEFI BIOS update is called as "BIOS Update CD".

The BIOS Update CD can boot the computer disregarding the operating systems and update the UEFI BIOS (including system programs and Embedded Controller program) stored in the ThinkPad computers to fix problems, add new functions, or expand functions.

Fixes:

- Fixed an issue of Windows Memory Diagnostic failure with two memory modules.
- Fixed an issue where no sound was heard from the ThinkPad internal speakers while the computer was locked when SmartAudio was set to Multi-stream mode and headphones or external speakers were attached to the computer.

  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.
