Thank you Tito for your replay , I appreciate that how can I backup that mac? my bios is 5FCN34WW , is it stable and safe to use 5FCN35WW ? please tell me the steps to reflash
Run ipconfig /all from cmd and note down the MAC address of the LAN card. I have personally tested this unofficial bios update but try at your own risk; just execute the exe and wait. It'll be seemed that your PC is hanged but don't touch it. After flashing it'll be rebooted automatically. The problem of not accessing BIOS or boot menu will be solved eventually.
so many thanks tito why i need to remember wireless mac ? after flash do i face any problem related to any drivers or wireless card (I use it all the time). do you recommend me to use uefi or legacy ar any other bios setting?
Not wireless, the ethernet one (should be Realtek chip). It will be erased while flashing. In my tests, no problem is found. Its your choice.
Hi, I have the same laptop. I previously set a password in my bios but cannot recall it. Would flashing the bios reset the password? Thanks for the bios. Flashing it got rid of the password. I was able to enable VT.
hi, is there any modded bios for the lenovo z580 ( i7 processor version) that allows me to unlock cpu freq multipliers ?
