Thanks Sir Trevor.

HpFirwareUpdRec.exe does exist on "$WorkingDirectory$BIOSUpdateDirectoryName$BIOSExecutable or (C:\ProgramData\Contoso\HP_BIOS_Update\2021-Oct-20_12.49.20\sp133197)

May I know what is this means? $BIOSUpdateDirectoryName = $SoftpaqFileName.Split('.')[0]

This comes ultimately from the download URL, in your case https://ftp.hp.com/pub/softpaq/sp133001-133500/sp133197.exe, which would result in $BIOSUpdateDirectoryName = sp133197.
Curious why it's not working as the file path at least seems correct. Perhaps it can't find the actual *.bin file, the payload for the update? Is AV at play here?

I have a similar issue. The softpaq subfolder is created, and the bin/inf file are there.

Hello,
I have the same problem than JrothSKV.
The problem seems to come from the directory of the line
{
$Process = Start-Process -FilePath "$WorkingDirectory$BIOSUpdateDirectoryName$BIOSExecutable" -WorkingDirectory $WorkingDirectory -ArgumentList "-s -p.\password.bin -f.$BIOSUpdateDirectoryName -r -b" -NoNewWindow -PassThru -Wait -ErrorAction Stop
}

If i start a cmd and lanch manually the bios exe with the password.bin with manual links pointing where the program and files swhere downloaded byt the script : it works///
So how could we solve the problem?

@dimitrov6

Ok, i find the problem. You must modify this line

{
$Process = Start-Process -FilePath "$WorkingDirectory$BIOSUpdateDirectoryName$BIOSExecutable" -WorkingDirectory $WorkingDirectory -ArgumentList "-s -p.\password.bin -f.$BIOSUpdateDirectoryName -r -b" -NoNewWindow -PassThru -Wait -ErrorAction Stop
}

With

{
    $Process = Start-Process -FilePath "$BIOSExecutable" -WorkingDirectory $WorkingDirectory -ArgumentList "-s -p.\password.bin -f.\$BIOSUpdateDirectoryName -r -b" -NoNewWindow -PassThru -Wait -ErrorAction Stop
}

And it works!

Thanks for the find @dimitrov6! I have verified it and updated the code in the gist. I think originally I was extracting just the filename in the $BIOSExecutable variable - don't know how I missed that off.

This is absolutely brilliant. In initial testing this has worked a treat with one exception; the password.bin file is being created in the correct folder but looks to be 0kb in size. I amended the Line 7 $BIOSPassword = "MyPassword" to the actual BIOS password.
I can't see any errors in the logs:
<![LOG[The BIOS has a password set]LOG]!><time="09:42:25.773+000" date="11-24-2022" component="BIOSPassword" context="" type="1" thread="" file="">
<![LOG[Creating an encrypted password file]LOG]!><time="09:42:25.778+000" date="11-24-2022" component="BIOSPassword" context="" type="1" thread="" file="">
<![LOG[File successfully created]LOG]!><time="09:42:31.877+000" date="11-24-2022" component="BIOSPassword" context="" type="1" thread="" file="">
<![LOG[Staging BIOS firmware update]LOG]!><time="09:42:31.877+000" date="11-24-2022" component="BIOSFlash" context="" type="1" thread="" file="">

Upon reboot, the device then prompts for a BIOS password to complete the update - what the heck am I doing wrong? :(

This is an excellent script. My org doesn't use Azure blob so I removed that and changed the logging. I've tested now on a few workstations with good success. Nice one!

I have verified I entered the correct password. I have tested this script on about 10 laptops, all of which have the same BIOS password. It creates a 0kb password.bin file, which is a blank password - but SOMETIMES is creates it correctly which is even stranger. The problem is if it uses a blank password, the end user will be prompted for the password when the computer reboots to actually apply the update.

I have a potentially more secure workaround; the BIOS password would be in cleartext in this script which may not be everyone's cup of tea. So an alternative option is to:

  1. remove Line 7: $BIOSPassword = "MyPassword"
  2. remove the Create Password File section from the script
  3. manually create a password.bin file using the HpqPswd.exe (it uses AES 256 if anyone cares to know)
  4. store the password.bin on a suitably accessible file share
  5. add the following somewhere after "Create Directory Structure" and before "Check for BIOS Password"
###############################
## Copy Encrypted BIOS Password #####
###############################
Copy-Item -Path \\server\share\password.bin -Destination $WorkingDirectory\password.bin
Write-Log -Message "Copied the encrypted BIOS password file (password.bin) to local computer" -Component "Preparation"

Of course, if the BIOS password changes and/or your organisation have multiple BIOS passwords floating about out there, then you'll need to consider having multiple scripts if not find a way to update all outdated devices to the newer password (https://www.danielengberg.com/hp-bios-configuration-utility-sccm/#Update_password_file_and_configuration).
