I understand that the one-key recovery system resets all the drivers back to the factory setting but does it also revert the BIOS to the factory version?
My laptop is the y560 series w/ a i7 CPU running window 7 64 bit. I am currently running BIOS 71. I updated from BIOS 59 to BIOS 71 some months back. Ultimately, my goal is to revert back to BIOS 59.
I'd appreciate any advice on downgrading my BIOS from BIOS 71 to BIOS 59. THanks

I appreciate your response. I regret upgrading the bios like half a year ago. upgraded based on the responses at that time period. Low and behold v71 is inferior to v59.
I've read all the threads about bios v71 and its overheating threads. I'm trying to find some procedure to downgrade my bios.
Is there a better approach to this problem or do i have to do something like this. I really do not want to fry my motherboard. I'm not really an expert on bios.
Poor product control. Certain companies spend millions on customer service and product control. Either there lead engineer sucks which i highly doubt or they don't care about quality. You get what you pay i guess.Theres a reason why lenovo sold my laptop at $750 on black friday 18 months ago lol.
You'd think Lenovo purchasing IBM's PC division would improve their quality. BTW all lenovo products come with cheap display panels.

OKR does not revert the BIOS version to the previous version.
Are you having heat issues after upgrading the BIOS?

I'm trying to change my BIOS back to v59 because BIOS 71 has overheating issues. The CPU under BIOS 71 runs conservative. IE underperforms when the system is under duress. The laptop reaches it's critical temps and shuts down when your playing games etc...
I am requesting some solid feedback about how to safely revert the BIOS back to v59.
Appreciate any help. Thanks

So, if you request, there're two links with some useful info about y560 bios downgrading and recovery (hope that you won't need latter, but who knows..).
There're some suggestions about using bios backup file for downgrading, but AFAIK many users report that it's dangerous. I also advice you to find as much info as you can before trying anything, because bios flashing is potentially dangerous operation.

I would first like to make this clear. If you are having overheating issues with your y560 DO NOT UPDATE TO Bios v71.
STAY WITH BIOS v59. Bios v71 has issues w/ the CPU fan. It won't fix your problem. It will only make it worse. I first posted and complained about it here.
I talk about the spikes but the CPU temp will eventually reach 95+C and shut your PC down.
I safely downgraded down to Bios V59 using the file at this site. The link is in Chinese text. Don't be scared. This is legit. Use Google translate and click one of the download buttons.
This file was also mentioned here.
I was very skeptical of using this file but i searched through another forum ( notebookreview forum boards) and they confirmed that it is indeed the y560 Bios v59. 64x. When you download the file it comes out as 27CN59WW64 but its mislabeled. It actually turns out to be 30CN59WW64 when you flash it. It even says 30CN59WW during the install/flashing menu.
One of the forum members commented on the file name discrepancy on this thread. Another thing to note. Listen to what the user khaledseif is saying. That man knows what he's talking about.
I hope my post can clarify some of the past issues with the y560.
Frankly, its quite pitiful of Lenovo for releasing a broken update.
