I just updated from 9.2 to 9.4. But I realized I can't unlock adjustable voltage in 9.4 for my i5-300H. Do I need to do some special settings ?

Does it show Locked? Sounds like the BIOS has locked CPU voltage control. Post a FIVR screenshot if you need help.

Yes, it does show locked, probably by the new bios. Is downgrading the bios a safe option? My previous bios version can work but I'm just worried that my laptop might not turn on anymore if I tinker with the bios.

Some people have bricked their computers when trying to downgrade the BIOS.

If you have a Dell laptop, here is how you can unlock CPU voltage control.


Is it safe? If you know what you are doing and nothing goes wrong. I do not own a Dell laptop so I have never needed to try this procedure.
