Anguel, I received a clarification on the BIOS version, 0ZCN30WW, which is already installed on your system. This is the latest BIOS available for your model. A possible reason for its installation was during manufacture it was needed to support the hardware configuration your system has. Since this BIOS is specific to your configuration, it is not needed by those who purchased earlier systems with a different hardware configuration and that would explain why it is not posted for public download. When you try to use one of the existing BIOS upgrade downloads, they are correctly aborting since they do not recognize the later BIOS version installed. I hope this helps explain the problem you have encountered.

Majestic, many thanks for the information. I still hope that Lenovo will officially support and update my notebook's BIOS in future as this is very important for business notebooks like this one. Also there have been recently discovered some microcode bugs in all Skylake CPUs that will require a BIOS update: http://www.theregister.co.uk/2017/06/25/intel_skylake_kaby_lake_hyperthreading/
Lenovo should still update their website to not offer the wrong BIOS for this exact model.

I don't see future BIOS updates as being a problem. I have a Thinkpad Yoga that had a hardware configuration change during its history of being manufactured. Lenovo handled this by releasing subsequent BIOS updates that would detect what design version it was and then update it accordingly. Likewise if the update didn't pertain to my version I got a pop up informing me of such. I suspect the same will be true for your system.

here is an later BIOS version, is it 0ZCN38WW, maybe the BIOS version is 0ZCN30WW in your laptop.
0ZCN30WW, 0ZCN38WW Applies to Skylake technology
2WCN25WW, 2WCN28WW Applies to Kabylake technology
If you want to update the BIOS version go to this link:
In my case the update worked so good.

Welcome to the Lenovo Community Jaime_P!
Thanks for posting. Is that BIOS update for the V510 as well? I see in the README file it only lists the V310 for compatible machines.

Anguel, have you verified that the download Jaime_P offered is also for the V510-15IKB ? All indications at this point would indicate that BIOS upgrade is for the V310 only.

Majestic, yes verified, the latest 0ZCN40WW BIOS update for the V310 ISK (it is actually also for V510 ISK as you see during install) works on my V510 IKB . Lenovo has messed up things completely as expected! My notebook's model is IKB at the end which should be an Intel Kabylake CPU as Jaime_P stated. However, the notebook has a Skylake CPU - Core i3-6006U! Therefore it makes sense that the BIOS for the ISK notebooks is correct, not the one for the IKB. Also, as you see the BIOS name for ISK models starts with 0ZCN... which is the same as my initial BIOS name. Can you please check back with Lenovo and let them clarify how it could happen that my notebook's model is incorrectly labeled as Kabylake although I have a Skylake CPU? Thanks.

You actually have what is called a Skabylake system which is a combination of Skylake and Kabylake.
What are Skabylake systems? - Because Kabylake CPUs will not support Windows 7, systems were built with Kabylake backwards compatible mainboards and Skylake CPUs in order that some corporate / enterprise customers could continue to deploy Windows 7. These systems are known as Skabylake.
In short 7th Gen boards with 6th Gen CPUs.
As a result of your system having a Kabylake board you require a Kabylake BIOS and not Skylake although, as you correctly note, your CPU is Skylake.
Also, as posted by Majestic earlier, you are on the latest necessary BIOS version for your system which has not been published to the web because it contains no fixes necessary for customers to install. Please do NOT attempt to install any other BIOS on your system other than one specifically offered on the Lenovo support site for your system type.

Andy_Lenovo, thank you for the information. However, I would like to know if this is official information received directly from the developers or is this just another "theory"? I have heard many "theories" from Lenovo support so far - each support employee actually has his own.
I am still not convinced. Every sign beside the "IKB" in the model shows that the Skylake BIOS is the one to be used, especially the original BIOS started with 0ZCN so I am pretty sure 0ZCN BIOSes, i.e. the Skylake BIOSes, are the correct ones to use. In contrast, the 2WCN BIOSes which the Lenovo website offers me for the IKB immediately deny installation while the ISK BIOS installs without any issues. Or do you want to tell me that leading PC manufacturer Lenovo is not able to do a simple BIOS compatibility check in the year of 2017 ?
I also don't believe the "theory" that there is no newer BIOS for my notebook as new BIOSes for both ISK and IKB systems are actually published almost every week, containing the same type of changes, look below:
Summary of changes ================== General Information: 0ZCN40WW 1.Update 0ZEC29WW EC version to fix battery can't charge problem. 2.Set Always On USB default is disable.
Summary of changes ================== General Information: 2WCN29WW: 1. Update 2WEC22WW EC version to fix battery can't charge problem. 2. Set Always On USB default is disable.
BIOS and EC Update went absolutely smoothly with the ISK BIOS and my system now runs without problems, see screenshot. Exactly as Jaime_P stated.
