W540 BIOS Update or not?

My BIOS version is 2.26. Now the recommended BIOS version is 2.32. Any expert can give me some advices about update or not?

 

Thanks,

I tend to update those things, but there is no right answer.  Here is the readme and you can decide if the changes are worth the (minor) risk.

I have tried twice to update my BIOS but none succeeded. There is no error message. After reboot, the Lenovo System Update UI is still showing BIOS update as one of the recommended updates. Check with Windows 7 System Information, the BIOS version is still 2.26. Cannot update BIOS via Lenovo System Update tool? 

 

Attached is the last screen of the updating process:

Lenovo System Update tells me different things in different location: one says installed, another says not installed:
