Thanks to a kind forum member here i managed to get a dump of my bios and am now looking for password removal if possible. was unable to dump all regions and i suspect the regions i couldn't dump have the password information but maybe im thinking too negatively lol. BIOS and DESC regions dumped along with a txt dump of FPT -i for bios information.

Thanks in advance for any help.
Try this...
cmd administrator ..
use fpt.exe -f xxxxxx.bin -BIOS
if you find error (ex. error 150) due to protected bios, try to hibernate mode first before you execute...
goodluck
Error 368: Failed to disable write protection for the BIOS space.
Just as you anticipated. Im unable to try Hibernate as no OS will boot with the bios locked. The only entry i have is Recovery Console, currently using win 8.1 as FPT didnt like windows 10 much. Im unsure if i can boot an installed os manually.
For now i shall try and see if i can get a windows to go usb to boot and if it does work ill try the hibernate trick.

Surface Studio, Surface Book, Surface Pro 4, or Surface Pro 3 without a configured boot order in UEFI
Shut down your Surface.
Insert the bootable USB drive into the USB port on your Surface.
Press and hold the volume-down button on Surface.
While holding down the volume-down button, press and release the power button.
Follow the on-screen instructions to boot from your USB drive.
Hey, I'm a noob here, but it sounds like some others have had the same problem I'm having. I have a Surface Pro 4 and can't get into the UEFI BIOS settings due to a forgotten password. I can boot into Windows 10 just fine but can't make changes to the UEFI settings.
Would flashing one of these "clean" BIOSes fix that problem? If so, how do you go about flashing it manually? I've downloaded a few of them but they all seem to be of varying sizes, but the majority are 16,384KB. However, even this is significantly larger than the official Microsoft firmware package I downloaded that shows 3,843KB in size.
I have the Surface Pro 4 with Intel M3 and 4GB of RAM if that makes a difference.
no the bios is corrupt i think this board bios chip size 16mb you send 10mb.read and save again.
Hi imranromi, thanks for your reply. I've been trying all day but the FPT program refuses to output more than the 10240kb as shown in the attached screenshot. FPT reads the total size of the BIOS as 16384kb as you say but when I run the dump command it just not pulling all of it.
I've also been unable to find another BIOS backup tool that works on Windows 10 and the Surface Pro 4.
If you remove bios password open laptop find bios chip and use bios programmer read and bkup upload the file. I try remove inside the bios file password.when bkup bios 16mb file need.
Can someone please take a look at my BIOS dump for my Surface Pro 4 and see if they can remove the password?
I dumped it using the FPTW64 -d bios.bin -BIOS command, so hopefully that is correct.
Thanks!
1. To get fulldump 16mb ,try without -BIOS : FPTW64 -d bios.bin
2. To makesure your 10mb dump can be flashing back with FPTW without failed.. please trying flash back your dump... if it successfully flashing back with FPTW , i"ll remove the password from your 10mb

Hi, thanks for your reply. I have tried without the -BIOS before and it complained it couldn't read that flash area or something to that affect.
I believe after writing to another member here with the same issue, that iamromroni is correct and the only way to get the full dump is to open up the tablet and read it using a physical programmer.
However, the Surface Pro 4 from what I've read is extremely difficult and time-consuming to get into without damaging it, so I'm not willing to go that far as long as my Windows is still working. I appreciate your assistance in trying to resolve this issue. This is a great forum!
