Hey you guys, I stumbled upon this thread by searching for a way to undervolt my Gigabyte Aero 15-SA through the BIOS, but as you two know there is no option for this in the stock setting. I thought about flashing the BIOS rom you provided but I am cautious because it says Gigabyte AERO 15-XA. Can I use this rom or should I modify my own AERO 15-SA? Everything except for this model signature is the same in my BIOS.

@Dixonism - Sorry I missed your comment until now! I can't use paypal I don't want to connect a bank to them anymore, and without that there is no way to use them
Two boot menus was part of the unlock goal here (it's in previous edit images you sent me too, maybe you missed it?) >> Swapped Main, Advanced, Chipset, Save & Exit, enable both boot menus -
This is because the hidden one does not have some settings that's on the original one, and it's easier that way for me. If you want me to move the setting/settings I mentioned from original to the hidden one and then leave only the new hidden one exposed I can do that, it just takes a lot more time.
I checked and it's just one setting in this BIOS >> OS Type, this is on original boot menu, but not on the hidden one, so that is why goal was both boot menus.
However, checking your images I see the settings I meant to reveal that I missed are not there either, did you maybe send me new images of the earlier edit and hadn't flashed in that final one yet?
Or maybe, I need to undo something, I left both methods in place to reveal, and it may only need the one I did this last time instead of previous edit + this last one
Here, in case you want to retest, show me the new boot menu (one on far right) - http://www.filedropper.com/fb05unlockedbackupmbcpf2

Sorry we couldn't fix that coil whine all the time! Gigabyte probably can, or at least make it less, but that is something they have to edit I can't do it

That wake issue, could be anything, some driver, some app, a ghost in the room
The only BIOS related setting for that is a wake at certain time type of thing, and I don't even think that is in this BIOS, but even if it was and it was set, it would be same time always and only at that time exactly each day.

@anphex - all BIOS here are user specific, so you can't use them. There are some SA dumps/BIOS posted early on, but he switched models, that's why you see SA and XA being discussed

If you want mod BIOS we need to get FPT BIOS region dump from your system and possible unlock some things first before you can flash in mod BIOS

Check BIOS main page and see if ME FW version is shown, if not then download HWINFO64 and on the large window on left side, expand motherboard and find ME area, inside that get the ME Firmware version.
Once you have that, go to this thread and in the section "C" download the matching ME System Tools Package (ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
Intel Management Engine: Drivers, Firmware & System Tools

Once downloaded, inside you will find Flash Programming Tool folder, and inside that a Windows or Win/Win32 folder. Select that Win folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the following command and send me the created file to modify >> FPTw.exe -bios -d biosreg.bin

Right after you do that, try to write back the BIOS Region dump and see if you get any error, if you do show me image of the command entered and the error given >> FPTw.exe -bios -f biosreg.bin

If you are stuck on Win10 and cannot easily get command prompt, and method I mentioned above does not work for you, here is some links that should help
Or, copy all contents from the Flash Programming Tool \ DOS folder to the root of a USB Bootable disk and do the dump from DOS (FPT.exe -bios -d biosreg.bin)

Meanwhile, tweaking the BIOS does help me get better temperature.

@Dixonism ^^ Unsure if quotes give you notification or not, thanks

@deathalo - what is your model variant? It's not necessary for the mod, but I'd like to know so I can keep your BIOS in a properly labelled folder with all the others from 15 OLED

@deathalo - BIOS lock is enabled, and you have no exit to shell on your exit page, so you need to do as mentioned here to unlock first, before you can flash in mod BIOS
BIOS Lock variable >> 0xB4D

Here's headkaze's method - How to set the BIOS Lock variable to 0x00 (Disabled):
1. Make sure you have following values set in BIOS:
- Legacy Support: Disable
- Secure Boot: Disable
2. Take USB stick and format to FAT32
3. Create directory structure EFI\Boot
4. Download and unzip bootx64.7z
5. Put BOOTX64.EFI into Boot directory
6. Boot from this USB stick
7. Run command: setup_var 0xB4D 0x00
8. Run command: reboot

Here's my method to make the USB, whichever is easier for you - [Help needed] Hidden Advanced menu Bios HP Z1 J52_0274.BIN (2)

Once you're done with that we can flash in the mod BIOS. And, once you do that, send me new FPT BIOS region dump, so it's disabled in your dump as base moving forward
Also, before making any FPT BIOS Backups >> Please remove all BIOS passwords, disable secure boot, and disable TPM or Encryption if you have enabled.

@deathalo - looks good, so you should be able to write back BIOS, sorry I didn't mention to test that but you can do it now if you want before I send you mod BIOS
FPTw.exe -bios -f biosreg.bin

Making you mod BIOS now
* Edit - please upload to another site, that one is not working for me at all tonight I can't use Mega, dropbox, or box either.
Here is two I always use that I can download from always

Thanks, but I was editing in above that I got it, so no need for re-up. Good you tested, thanks

BIOS mod coming in maybe 10-15 minutes then

*Edit @deathalo - here is unlocked BIOS - http://s000.tinyupload.com/index.php?fil...374732937612300
Flash via >> FPTw.exe -bios -f biosregm.bin

*** This BIOS is for deathalo ONLY, do not use if that is not your username!
Otherwise you will loose your serial, UUID, possibly LAN MAC ID and windows activation etc. You have been warned! ***

Thank you! It worked perfectly!

@deathalo- You're welcome, and thanks for quick report back

Dear @Lost_N_BIOS

I have the same laptop as the poster before, the Aero 15 OLED SA
Your help in unlocking my BIOS would be greatly appreciated and i will be sure to help improve your hardware in return.

The link to the FPT dump is: http://s000.tinyupload.com/?file_id=74000923075155833716

Thank you for your great work!
