I was given a HP all in 1 pc with a 10 point 23" touchscreen, it has a Haswell i5 cpu and ssd, im a born tinkerer and would love to open up the units full possibilities in the bios as its pretty basic as with all shop bought pcs.
It runs absolutely mint, from pushing power to loading windows is 5 seconds flat, however i know it has so much more potential as ive looked inside its bios with AMIBCP. there are literally hundreds of locked settings that i dont know how to enable, its an american megatrends bios.
this is the machine: https://support.hp.com/gb-en/drivers/sel…1/model/8587627 HP Pavilion All-in-One - 23-q055na
Could someone give me any pointers on how to achieve this?
Cheers.
@POE_UK - Start here 
Unless you have flash programmer, and it may still come to that too. if you have flash programmer, you can ignore below if you want, dump BIOS and send to me
What is your ROM Family SSID? You should see this I think, if you run the stock BIOS Flash update tool. I need to know this, so I can download the correct stock BIOS for your system (There is two BIOS for different system at the link you gave)
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)!!!
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…))
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!!! <<
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
> CLICK HERE TO DOWNLOAD CMD PROMPT REGISTRY ENTRY <
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 " )

An H81 microboard. Onboard GPU, x1 SATA port, x1 m.2 slot, x2 dimms and supports 35w Haswell T.
What are you hoping to achieve?
This ones got 2 sata ports, haswell quad core hd4600 graphics, think ill take out the m.2 wifi card and fit an ssd in its place, would a 2242 sized one fit you think? its a surprisingly fast computer, the cpu cooling solution seems pretty decent and is very quiet. i think the cpu can be upgraded to an i7 as well. as it sits now it totally destroys my old amd fx 8300

@POE_UK - please see post #2, do that with FPT and let me know outcome. Do you have flash programmer or not?
Toothache, bloody toothache cant think straight atm.
