Here is the problem, sadly, i am not the only one that has it- So, i have this perfect z580 ideapad which got a BIOS update before few years... and it started running slow, and some other problems appeared. So i want my old BIOS back. The new one is the 5FCN95WW... but sadly i have no backup of the old BIOS, i think it is 5FCN34 or 35WW. I saw tons of information around the internet, many posts here in the Lenovo forums, i've downloaded countless files, used many programs, even backed up my own BIOS and nothing.
I haven't seen even 1 solution from point A to point B for "How to backup and then flashback to the old bios again if needed", so please, tell me what can i do.
1: How can i obtain a file of the old good original BIOS
2: I have 2 Lenovo z580 laptops and just one of them is with the new BIOS, the other one has the old BIOS - can i somehow make a file of the old BIOS, transfer it to the other laptop and then flash back to it.
Thank you in advance, i hope to see a good answer these days, which will save me much troubles.
