End-state goal : Unlock a screen like the below in my BIOS.
Does anyone know how to achieve that? Tried everything I could google : Fn + Tab (3 x), Fn + R -> Fn + N... and various other magic to unlock 'Advanced' tab in my UEFI.
Motivation : Disable C1E and access CPU Power Management tab (for potential undervolting). The former helped me completely get rid of coil whine (demoe-ed below), thanks to ThrottleStop SW. However, I would like to config the same in BIOS so the fix becomes OS-independent

Many thanks for guidance to all you gurus out there.
On my Ideapad 5 this worked to unlock advanced BIOS options (not sure if there will be the option you're looking for):
(remember to first disable "One Key Battery" from the BIOS)
Power off the laptop. Power button to turn on → F2 to enter the normal BIOS → Power button to turn off → then press the following keys in sequence:
F1 → 1 → Q → A → Z
F2 → 2 → W → S → X
F3 → 3 → E → D → C
F4 → 4 → R → F → V
F5 → 5 → T → G → B
F6 → 6 → Y → H → N
Power button to turn on → F2 to enter the BIOS which should now have an "Advanced" tab
In my experience, you need to do this every time as the tab doesn't remain visible after a restart.
I'm curious, exactly what variant of IdeaPad do you have?
Lenovo has been notorious of not allowing users to access advance bios settings, but recently I have found a way to access this options in the bios menu. I have only tested this on Lenovo Ideapad gaming 3 15ACH6. Steps are as follow:Step 1: Turn off you laptop completelyStep 2 : Press the power button to turn onStep 3 : Spam F2 to enter BIOS menuStep 4 : After entering BIOS, DO NOT PRESS ANYTHING EXCEPT THE FOLLOWING KEYS : Press Fn+R+N for 3 times.Step 5 : Press F10, then enter to save and exitStep 6 : Spam F2 again until you are in BIOSStep 7 : You should now see some hidden options, Enjoy!
WARNING: By doing this, you *may* void your warranty or damage your hardware. Make sure you know what you are doing before changing anything within the BIOS. I soft bricked my laptop twice when messing with the options. I am not responsible for any damage cause by accessing the advance optionsPersonally I only changes the cpu power profile to the 54W profile, along with the use of AATU(aka UXTU) I managed to increase the performance by quite a bit. CinebenchR23 score before tweaking was 8906, but after tweaking the score increased to 11233 while maintaining <95℃. There are options for RAM speed but I didnt use those because I am not familiar with them. I really dont understand why Lenovo have to limit this laptop so much and not give us any easy option to boost the performance, there are plenty of thermal headroom in this machine. And total power isnt a problem as the cpu can run at 50W with gpu at 90W for over 10 minutes without any problem(no throttling no thermal problem). Lenovo why?Credit : I saw this method from https://youtu.be/mmd4Sc5bVcIAATU/UXTU : https://github.com/JamesCJ60/Universal-x86-Tuning-Utility

Bios: EGCN36WW
(Had seen an newer version, 40ww on support.lenovo.com, but Vantage doesn't seem to recommend it when searching for updates)
I had read somewhere on the net that there are power saving options that maybe available in the advanced bios. Planning to take a look at the options and try them if they are safe.
I have tried the Fn + R+ N (x3) option after pressing F2(ending up in the screen with the option to change the boot order of drives). Have also tried it after clicking on more settings there and entering the bios settings.
Thanks in advance.
Im trying to change base clock i wouldve posted on Lenovo forums buts the supports justs responds with
"Unfortunately the advanced BIOS menu is meant for developers and repair use.
Any discussion regarding advanced options are regarded as modification which is not supported.
Our machines are already pre configured from the factory to perform at peak performance. Any current limits set is based on the recommended and tested configurations of our engineering team."
They are lying and are just saying that so i dont turn this laptop into a gaming one. Could someone please tell me
