Yoga 2 Pro - BIOS update - Risks and opportunities

2015-10-17, 12:27 PM

Hi,

 

I just noticed the BIOS version on my Lenovo Yoga 2 Pro was slighlty outdated : 76CN38WW, 27-06-14 instead of 76CN43WW, 13-08-15.

 

As I have never made such an update, I wanted to know if there were any risk of crashing / loosing data by doing such an update if you stick to the recommendations (laptop on power supply, not shut down during operation,...)

Is it meaningful to update the BIOS version ? If yes, why ?

 

Notice that when I run the diagnostic tool of Lenovo, it doesn't recommend me any Bios update.

 

By the way I didn't get notified about this update. How is it possible to get an alert ?

 

Thanks in advance for your answers.

 

Philippe

Unless you have problem with your current BIOS, I don't recommend to update the BIOS.  One known issue with Lenovo BIOS update is they do update the "blacklist" for wifi adaptors.  Let say you need to replace your wifi card or want to upgrade the card with someting supports 5GHz, the new BIOS will make it impossible.  It will tell you the card is unsupported and won't let you past the POST.

Hi,

 

Thanks for the tip. As I don't face any issue with the current BIOS, I'll keep it.

 

Thanks again
