This PowerShell script automates HP BIOS updates using the HP.ClientManagement module.
It compares the current BIOS version with a target version and applies the update if necessary, while logging all actions.

✨ Features

Imports HP.ClientManagement module
Logs all steps to C:\windows\temp\HPBiosUpdate.log
Retrieves and displays the current BIOS version
Checks available updates with Get-HPBIOSUpdates
Compares against a target version (2.20.01 in this example)
Runs update automatically if the current BIOS is outdated, with BitLocker suspend

📌 Requirements

Windows with PowerShell (run as Administrator)
HP device with HP.ClientManagement module installed
Access to HP BIOS update packages

🚀 Usage

Edit the script and set the target BIOS version:

$TargetBiosVer  = [Version]"2.20.01"

Run the script:

powershell -ExecutionPolicy Bypass -File .\HpBiosUpdate.ps1

⚠️ Notes

The script suspends BitLocker before flashing the BIOS.
A reboot is usually required after the update completes.
If the current BIOS version is equal to or newer than the target, the update is skipped.
All actions and results are logged in C:\windows\temp\HPBiosUpdate.log
