Sometime in the past I setup a password to prevent BIOS access. I forgot it. It was a long time ago.
Is there a way to remove (i do not care about recovery) the password for BIOS access?
I want to update BIOS, as well as asset numbers and some other configurations.
It is a Probook 4440s. Running Windows 10 64 bit in english. (yes...still going strong this notebookis ;))

Hi,
You will need to Contact HP Business support - they should be able to send you a customised SMC.bin file which you can use at boot to reset the password.
You can contact HP Business Support in your country via
http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html
or
https://support.hp.com/us-en/contact-hp
Just to note, don't try removing the rtc battery. It won't remove the password, but it will reset the clock - as smc files are time coded, a large disparity between the system clock and the time encoded in the smc will cause it to fail.

Thanks for the reply.
I found these pages in the support website.
HP Elite/ProBook Notebook PCs - How to Remove BIOS ProtectTools User Account
HP Commercial PCs - Using BiosConfigUtility.exe (BCU) to Set a BIOS Administrator Password
https://support.hp.com/us-en/product/hp-probook-4540s-notebook-pc/5229455/document/c03161127/
however since BIOS has password, I cannot set a blank or new password because BIOS has one
C:\SWSetup\[sp88497>BiosConfigUtility.exe/nspwd:"1234567890" <BIOSCONFIG Version="" Computername="DESKTOP-I4F0QAV" Date="2018/07/09" Time="22:26:11" UTC="19"> <ERROR msg="Unable to process command. Password is set, but no password file is provided" /> <ERROR msg="BCU return value" real="10" translated="10" /> </BIOSCONFIG> C:\SWSetup\[sp88497>

Hi,
You're welcome.
As you mention, both of these require knowledge of the existing password and I don't believe there is any 3rd party software that will work for this model - unfortunately, I think the only option is to request a smc from business support.

For community purposes:
In order to succesfully remove/change the password stored in BIOS in case you forgot it:
1- Do not remove the battery trying to reset the RTC clock. It will make things worse.
2- use the biosconfigutility found on the previous post to get the UUID of the affected system.
3- Contact HP (not HPE) support and ask nicely if the can generate a SMC.bin for you.
4- when they send you the smc.bin inan email then
USB Flash Drive of 4GB or lesser size formatted as FAT32 File system. Bigger sized flash drive may not work.
*You can also create the 2GB HP_TOOLS Partition from the link below if you do not have a smaller flash drive.
Link: http://ftp.hp.com/pub/softpaq/sp52501-53000/sp52509.exe
Steps:
1.Save attached smc.bin file in this e-mail to the root of a USB flash drive “(or save the file to the root of drive 😧 HP_TOOLS*)”
- Power the notebook OFF.
3.** Hold down windows key + up arrow + down arrow and power the notebook ON.
- Let go of the keys at the HP splash-screen.
- Press F10 repeatedly at the screen that shows up with a message, "SMC command handled successfully"
- This should bring you into the BIOS where you need to choose “Reset BIOS security to factory default” and confirm by choosing Yes.
- Exit the BIOS, saving changes.
Reasons for SMC command failure:
- a) Wrong UUID provided
- b) Wrong Serial number provided
- c) Wrong Date set on the PC
- d) SMC file used after 7 days of issue
NOTE: ** If step 3 does not work, download and run the program from the below link to create HP_TOOLS partition on the PC Hard Drive.
Link: http://ftp.hp.com/pub/softpaq/sp52501-53000/sp52509.exe
I hope this works for others!!!
