Try to clear CMOS remove battery on MoBo !
There are few options to follow !
I am sorry Sad

, I forgot to advice to don't touch Significative Settings as Video Parameters . . . I prefer don't modify these Bioses as too much users have trouble.

Hello,

I have a Lenovo G500 with bios 78cn25ww (v2.03).

This is the bios link from Lenovo ->
http://download.lenovo.com/consumer/mobi...cn25ww.exe

BIOS Backup made with Universal BIOS Backup ToolKit 2.0 ->
https://www.dropbox.com/s/syqo42hqfd59ev...9.rom?dl=0

Attached you will find my current bios settings.

I would like to have the advanced settings unlocked, more specifically, I just need to change the default HD4000 VRAM value.

If it doesn't add any more risk than unlocking advanced settings, I would also like to have wifi whitelist removed, but that's only a "nice to have".

Could it be done safely?

Many thanks.

Best regards,
Khalonn.
