If you check the 'AMITSESetup' variable it uses 40+40 bytes for password storage, one of these 40-byte blocks is for the USER password and the other block for the SUPERVISOR password, if you see one of these blocks filled with just 00's is because the corresponding password is not set.Leave a comment:

Re: Microsoft Surface Pro 3 UEFI password
I could have sworn that somewhere in this message thread I saw an image that highlighted the code immediately after 'AMITSESetup', and on mine, everything right after it was 00's. In searching back through now, I see that the image showed it was the data after the 00's that was what I should have been using. If I take the data after that, which is exactly what you quoted AAAC, popping that into the spreadsheet immediately spat back that cursed '1234'!!!
AAAC, I bow to your magicThank you again!!!

When using UEFITool NE and other Hex tools you have the option of doing a string search in ASCII or UNICODE (8-bit vs. 16-bit representation, respectively), with UEFITool NE the option UNICODE is checked so you just untick the option and you are ready to find AMITSESetup variable for this BIOS (in other BIOSES you may require the Unicode option to be ticked).
Password XORED in AMITSESetup variable =
6A93842622BA584DC7E022747D07D89A332E8EC1E95444E89F7BFA0E55A2B0350BC9665CC1EF1C83
password = 1234I definitely don't remember setting it to that! There are a few passwords I reserve for BIOS stuff, and that's definitely not one of them! Thanks so much for this AAAC! I will poke back into the .bin file to find that data, and figure out where I was going wrong.

When using UEFITool NE version, while searching for "AMITSESetup" it will give the results, clicking on any of them will take you to the UEFI variable or module where it finds a match, when working with UEFI variables it may show the DATA or show a LINK to it (Subtype column), if the variable is shown as a LINK, right click on it and select option GO TO DATA (CTRL+T).I'll still keep trying though, since I hate not being able to figure stuff like this out
Thanks for your help AAAC!

Re: Microsoft Surface Pro 3 UEFI password
I did that. There were three locations with "AMITSESetup", all three were full of 00's. I will have a look at that tool you suggested when I get home from work tonight.Leave a comment:

I suggest to look for the next "AMITSESetup" match (usually by pressing F3 key). Other option is to use UEFITool NE version.Leave a comment:

Re: Microsoft Surface Pro 3 UEFI password
Hi folks,
I have a Surface Pro 3 that I can (kinda) get into the BIOS, but most of the options are greyed out. So I'm guessing that I put a password on it at some point (bought the thing used off eBay a number of years ago), but I'll be damned if I can remember what it is now. I used the fptw64.exe tool to extract the BIOS to a .bin file, but when I open the file in HXD, the location for the data I'm looking for (after "AMITSESetup") is filled with 00's. I have tried a few times, same results each time. Any ideas?Leave a comment:

Hi bodies,
Anyone now if those methods are valid to MS Surface Laptop 2?

You canβt find variable because you have a MS Surface Book 3 and not a MS Surface Pro 3.
Most likely you will need a BIOS chip programmer.Leave a comment:
