Y700-15ISK Bios Update Inquiry

2016-09-22, 9:45 AM

Hello all,

 

I recently bought a Lenovo Y700-15ISK and as I downloaded the drivers, I stumbled upon the BIOS update. There are 2 bios updates one marked as CDCN35WW and another marked as CDCN52WW having the same release date. My laptop currently has a BIOS version of CDCN27WW, 12/11/2015.

So my question is which of these 2 BIOS updates do I download and apply? Do I first apply CDCN35WW and then CDCN52WW or do I apply only CDCN52WW (maybe it contains CDCN35WW)?

Also what steps do I need to follow to properly flash the BIOS with minimum risk? My current BIOS settings are UEFI with an SSD as the boot disk with all the other settings not touched.

 

Thanks,

Penthon

Solved! See the solution

You will have to first update to 35 and then to 52. I dont like 52 because it has a new ugly logo.

I didnt do any special steps. I just downloaded the .exe and run it, then after a couple of restarts the bios is updated

I am a volunteer in this forum and also a lenovo user. If i helped you, click on the kudos button!

Ok, did it and now BIOS shows the new updated CDCN52WW version.

I don't care much about the new logo (the rectangle with colors and LENOVO logo-it's only shown for 0.5 second lol) as much as updating to the newest working firmware/software available so that my machine works at its best abilities.

Thanks for the instructions though, cheers!

And to get full speed on the DMI.

And to have a fixed graphics card. Having it dynamic is really stupid as you will ALWAYS use the base graphics card for just everything. HP has switchable graphics in FIXED mode, you setup in the bios whether dynamic or fixed. In fixed it will 100% use whichever graphics card you choose.

 

This laptop really needs a decent bios update. In its current state its SO LAGGY because of the switching between cards its just useless....
