Please, does anyone know how to install the new drivers without a problem? if not at least how to rollback bios to 57?
Mine is the Ideapad Y560 i7 720qm with ATI 5730 card. No switchable graphics.
Bios flashing with the same 59.exe file?

check c:\bios folder for winphlash.exe. then run winphlash.exe with admin privilages
( right click and select "run as admin" )
select previous file. then click flash bios.
warning: do not power off or restart your computer during the bios flashing process, which will cause serious damage and improper functioning of your computer.
warning: re-flashing bios backup may brick your main-board.

I restored My system after the bios update to see if they would revert back to ver. 57. Now how can I revert them back? There is no Bios folder Is there any other way?

Here are posted the BIOS 53, 57 and 58 downloaded from the Lenovo site, with the original installer.

I was running on bios version 53 before, but the people at the repair depot flashed it to version 71, which I am not satisfied with. When my computer came back from repair they had reset my hard drive, so I no longer have the BIOS files on the hard drive, and pepemosca's link above is no longer working, so is there anyone here who has the old BIOS files and could upload them? I would greatly appreciate it.
