Acer VX5-591G Unlock Advanced Tab Bios (Insydeh20 rev. 5.0 bios)

Hello again,
I did manage to ungray the ICC option, and now I can insert a number there. I have tried to change the value from 0 to 1, 2 and some couple more, but when I save and reboot it is always back to 0. Maybe there is a specific number to attempt? Since there is no number profile to choose from, just a empity fill box in there.
Thx for the repply.



I tried to do the same, but it’s different unlocking the advanced tab menu.

Sorry my bad language.

I need to unlock advanced tab too!!! Please, help me…

My BIOS is acer vx5-591g c5pm2 la-e361p v1.08 rev5.0 …

@Lost_N_BIOS @Mártin BRM Could you teach me how to do it? I got 0 experience in editing BIOS file, I have been trying to learn it via google, but haven’t found the proper ways to do it (which is scare me, because I might brick my laptop).
what I wanted to do is unlocking the advanced menu tab, I just bought spi-programmer+soic8 clip and managed to dump my bios

here is my hardware info:

Acer aspire VX5-591G
Intel I5-7300HQ - Nvidia GTX1050Ti
Bios vers: V1.08

@felix185 - Sorry I missed your post until now! But, this thread and anything mentioned here does not apply to your model, once you reply I will split and move this over to the 571G thread
Here is your unlocked E5-571g-57MJ BIOS -…596303860683916

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don’t try to disable one card or change which is main etc.

Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

WARNING *** - This BIOS is user specific! If you are not user felix185 at forum, DO NOT USE THIS BIOS!!
If you do, and you are not felix185, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

@Ov3rCl0ck5 - Do you have flash programmer? If yes, dump your BIOS and send to me, if not, do below and tell me what error you get at step #2, and send me file from step #1 -
You may need flash programmer, not sure, we can try without and see if we can make it happen

If you have already modified the BIOS in ANY way, you will need to re-flash it back to factory defaults using factory method (NOT FPT)!!!
Additionally, please remove all BIOS passwords, disable secure boot, and disable TPM or Encryption if you have enabled. Do this before moving on to below

If you do not have Intel ME drivers installed, install them now from your system driver download page, then start over here after reboot.
Check your BIOS’ main page and see if ME FW version is shown. If not then > DOWNLOAD HWINFO64 HERE <

Once HWINFO is open, look at the large window on the left side, expand motherboard, and find the ME area.
Inside that section is the ME Firmware version. Take note of the version. (ie. write it down or get a screenshot)

Once you have that, go to the thread linked below, and in the section “C.2” find and download the matching ME System Tools Package for your system.
(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)
> DOWNLOAD " ME System Tools " packages HERE <

Once downloaded, inside you will find Flash Programming Tool folder, and then inside that a Windows or Win/Win32 folder (NOT x64).
Highlight that Win/Win32 folder, then hold shift and press right click. Choose “open command window here” (Not power shell! >> * See Registry file below *).

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

((If “open command window here” does not appear, look for the “Simple Registry Edit” below…))

Step #1

Now you should be at the command prompt.
You are going to BACKUP the factory un-modified firmware, so type the following command:
Command: " FPTw.exe -bios -d biosreg.bin "

>> Attach the saved "biosreg.bin ", placed into a compressed ZIP/RAR file, to your next post!!! <<

Step #2

Right after you do that, try to write back the BIOS Region dump and see if you get any error(s).
Command: " FPTw.exe -bios -f biosreg.bin "
^^ This step is important! Don’t forget! ^^

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

Here is a SIMPLE REGISTRY EDIT that adds “Open command window here as Administrator” to the right click menu, instead of Power Shell
Double-click downloaded file to install. Reboot after install may be required

If the windows method above does NOT work for you…
Then you may have to copy all contents from the Flash Programming Tool \ DOS folder to the root of a Bootable USB disk and do the dump from DOS
( DOS command: " FPT.exe -bios -d biosreg.bin " )

@Rygen29 - Send me your dumped BIOS, or see post #8-16, I explain how to unlock your model and that exact version of the BIOS (Mártin BRM was on 1.08 BIOS too, so edit is same for you)

@Lost_N_BIOS Hi, thank you for replying my post, I just tried the post #8-16, which is succeed. I manage to edit my bios via SPI-programmer+SOIC8 clipper with CH341a software… but it seems my problem can’t be solved this way…
the reason I want to unlock the advanced menu tab is that I might fixed blank screen after installing graphic driver by changing the default GPU adapter that maintain the display to my dGPU instead iGPU ( I tried to change from IGFX or SG to PCIE and resulted on blank screen, I had to remove my BIOS battery to reset it). I have been facing this problem for a month, installing older driver, newer driver, etc. my laptop is currently running with microsoft basic display adapter and NVIDIA Graphic, but I can’t change the display brightness, Can’t connect to HDMI and anything that run on fullscreen will get like 1FPS-10FPS because non existence of IGFX driver ( Intel Graphic driver). Do you have any experience regarding this problem?

again, Thank you for reading

@Rygen29 Hey! I have exactly the same problem with the same hardware. It drives me crazy. I also use linux and the problem persist in linux as well. So that means the problem is a hardware mulfunction. Could you solve this problem?


@Rygen29 i have same problem like this…
And cant find any solution …:sob::sob:

unfortunately, I haven’t found the solution yet. I bought another Laptop already, and been in hiatus to solve the problem ever since, I did open another discussion and request. let’s see what we got



The solution is really easy. Just turn off Laptop, then press and hold both FN and TAB key and while holding push power button, then hit F2 key to enter bios. So this is how you accidentally enabled advanced settings
