Followed all the steps and did not work for me. IDK why. It seems the new Bios is installed, but my notebook is unable to load the windows 10 (when I power it, the black screen is there yet). Now, my second screen is not working. Can someone help me?

Hi here!

 

It's the second time it happens to my lenovo Y70 Touch. I've fixed it again with the steps from this topic. 
 

TIP: It is not necessary to plug off the battery in my case, so everything took around 10 min.

The solution has been suggested by @Koni5560 worked for me too. You believe or not, it works. The problem was the most annoying computer problem I ever had. At the first time after i release Fn+B keys nothing happened and i tried the solution more couple of times. These are my changes to the original instruction which been suggested by @Koni5560:

 

1- i tried the solution with bios ver 3.0 (not 3.03). ver 1.14 didn't work for me.

 

2- file names were the ZIVY2 set.

 

3-I chenged the file names ( and extensions )simply with windows explorer not notepad++.

 

4- before trying the solution for the last time, I changed the RAM's in each slot with each other. I'm not sure it was effective or not.

 

 

 

The other thing which I want to mention is after recovering/ reflashing the BIOS successfully, I faced with another problem. After working with the machine for some minutes (normally 5-10 minutes) some horizontal filck had been appear on screen and after that the laptop restarted and this happened every time. I fixed this problem simply with downloading and updating BIOS to ver 3.03 (last available version) from lenovo official site ( see related ReadMe note ver 3.03 for installation guide.).If it's your case too, I suggest disabling Intel HD card via device manger before updating Bios to ver 3.03. ( to avoiding laptop restart during Bios updating process).
