lenovo u310 bios update problem

[matt_slow]

Hi everyone

I am writing because i run out of ideas and options.
I wanted to make a hackintosh from laptop, baked up data, cleared hdd, installed new sdd, ram and wifi, and that where problems started.
Since my card was not on the whitelist i updated BIOS with one that has whitelist removed - 65cn99ww.

After update, everytime i want to start installation of os x, windows or even boot linux usb, screen dims out, like backlight control is not being controlled/functioning. 

at the beginig i suspected os, but after several trys with different os installations and linux usb i think the problem is BIOS.

Since i cannot see anything on the screen cant install windows and update BIOS by Lenovo tool.
Dos works, i am able to update through dos utilty, but i cannot find anywhere the *.bin or *.wph file of original BIOS.

Did anybody had similar issue, maybe you guys have any ideas what to try.

Like I said i run out of any possible solutions, and i am hopeless...
