Lenovo Vantage fails to install BIOS update on Y520

I attempted to install the new Y520 BIOS release in hopes of addressing recurrent wake-from-sleep issues. The "System Update" function in Lenovo Vantage shows "BIOS update - 10 [64] V.4KCN41WW" but will not install it. The resulting message is "Failed installed on 1/25/2018 at 6:40 PM".

Re: Lenovo Vantage fails to install BIOS update on Y520

Something is amiss. 

Support page states version 40.

I do see foot prints of 41 , 12/26/2017.

What is your MTM and OS version?

I suspect 41 pulled due to INTEL/AMD recall.  Just SU/Vantage catalog is not updated to NOW? I will explore SU catalog with MTM you provide. Thanks.

Re: Lenovo Vantage fails to install BIOS update on Y520

Your system update catalog:

https://download.lenovo.com/catalog//80WK_Win10.xml

It offers this BIOS: Level 41 dated 1/09/2018

https://download.lenovo.com/consumer/mobiles/4kcn41ww_2_.xml

 

Your support page is now showing level 40. Manually install level 40 to see if sleep issue is resolved.

Re: Lenovo Vantage fails to install BIOS update on Y520

Via Lenovo Vantage I was trying to update with BIOS 4KCN41WW and luckily it failed.

Probably (I hope) because Lenovo has included something to make it fail before install.

Intel has withdrawn lots of firmware updates they sent to implementors of their processors because of problems:

https://newsroom.intel.com/wp-content/uploads/sites/11/2018/01/microcode-update-guidance.pdf

 

If I log in to the Lenovo support site and look for available BIOS updates the newest available is 4KCN40WW.

That one does not include solution to CVE-2017-5715 (Lenovo ID: LEN-18282).

If you look at:

https://support.lenovo.com/kr/en/solutions/len-18282#ideapad

you see the status is "Researching".

 

Just wait until proper implementation is there.

Re: Lenovo Vantage fails to install BIOS update on Y520

Thank you, I will take no action. I am occasionally seeing push notifications telling me to update my BIOS but in vantage the only option is 4KCN41WW, sounds like they don't have their acts together yet on this one.

Re: Lenovo Vantage fails to install BIOS update on Y520

I have a similar issue. I previously installed version 4KCN41WW of the BIOS, and now I cannot install version 4KCN40WW, which is apparently newer, because the update utility thinks it's older based on version number.

Re: Lenovo Vantage fails to install BIOS update on Y520

i got notification to update my bios to 4KCN41WW and update was successful, after 2 weeks i checked driver & software section in lenovo support and there was 4KCN40WW dated- 25-1-18. now i am confused should i manually update it to 4KCN40WW or let it be what i installed.
