Although this is an old thread and I'm not certain if the issue has been addressed otherwise, I can confirm that the auto shutdown issue is a bios problem and that downgrading to version 59 solves the problem by allowing the fan to run at an appropriate speed relative to system temp.
You can download version 59 by following the links in this thread:
The links are not in English so you will have to click around a bit to find the right link :/ Sorry but I don't know where else to download the old version. Lenovo please fix this issue!!! Lenovo laptops are great and I have always recommended your brand. Until this issue is resolved you will get negative marks and no recommendations from me!
I attempted to boot into safe mode to troubleshoot an unrelated issue today and experienced an abrupt shutdown. Since then the fan control issue has returned. Still on BIOS version 59. So Lenovo.....any help on this?!

Dear Lenovo engineers,
I have 1 major questions:
I had the same issue like all ideapad y560 users: I bought my laptop with 59 bios version, I upgraded it to 71 and I had heating problems...which dissapeared when I downgaraded back to 59.....
now....I see on your Lenovo support that the last update available is : 30CN71 from 17 feb 20122.
Question: Is this upgrade safe or it will overheat again and I will loose time downgrading again? Did you fix it...I think we all offered a lot of feedback...so please give us a feedback!

Are any the lights functioning?
If no, then you have bricked your motherboard somehow and you will have to get your motherboard replaced.
BTW, there is another guide also if you can try once,

My fan speed is always o n 100% of its state without relying on the temp
I've noticed from this topic that most users problems are solved by downgrading to version 59
Is there any body here that has the version 30CN59WW
All the links containg this version are dead. I need some one who has this version available so that I could be able to flash my BIOS to this version and solve this problem
my left ear is going to be lost since the fan noise is too much at its 100% stage.
