Syntax
Update-HPFirmware [[-Password] <String>] [-File] <FileInfo> [[-Quiet]] [[-BitLocker] <String>] [[-FilenameHint] <String>] [[-Force]] [[-Offline]] [[-NoWait]] [<CommonParameters>]
Update-HPFirmware [-PayloadFile] <FileInfo> [-File] <FileInfo> [[-Quiet]] [[-BitLocker] <String>] [[-FilenameHint] <String>] [[-Force]] [[-Offline]] [[-NoWait]] [<CommonParameters>]
Update-HPFirmware [-Payload] <String> [-File] <FileInfo> [[-Quiet]] [[-BitLocker] <String>] [[-FilenameHint] <String>] [[-Force]] [[-Offline]] [[-NoWait]] [<CommonParameters>]
Description
This command updates the system firmware on the current platform. The update must be provided as a BIN file and can be obtained via the Get-HPBIOSUpdates command.
Parameters
| Name | Argument | Description |
|---|---|---|
| Password | <String> | Specifies the BIOS setup password, if required. Use single quotes around the password to prevent PowerShell from interpreting special characters in the string. |
| PayloadFile | <FileInfo> | Specifies the payload file to authorize firmware update. Refer to the New-HPSureAdminFirmwareUpdatePayload command for information on how to generate the payload file. |
| Payload | <String> | Specifies the payload to authorize firmware update. Refer to the New-HPSureAdminFirmwareUpdatePayload command for information on how to generate the payload. |
| File | <FileInfo> | Specifies the firmware update binary (.BIN) file. If the filename does not follow the pattern 'U70_010101.bin', the -FilenameHint parameter should be specified. |
| Quiet | If specified, this command will suppress non-essential messages during execution. | |
| BitLocker | <String> | Specifies the behavior to the BitLocker check prompt (if any). The value must be one of the following values: - stop: (default option) stops execution if BitLocker is detected but not suspended, and prompts - ignore: skips the BitLocker check - suspend: suspends BitLocker if active and continues with execution |
| FilenameHint | <String> | Specifies the original file name without the .bin extension if using a file name other than the original file name. Alias -filename_hint. Some older generations of platforms require that the filename of the BIOS update be in a specific format (e.g.: 'U70_010101'). If this parameter is not specified, this command will extract the file name from the -File parameter. However, if it does not match the required format on platforms that require a specific format, this command may fail. If the system does not require a specific format (not required on most recent systems), this parameter might be ignored. |
| Force | If specified, this command will force the BIOS update even if the target BIOS is already installed. | |
| Offline | If specified, this command selects the offline mode to flash the BIOS instead of the default online mode. If specified, the actual flash will only occur on reboot at pre-OS environment. | |
| NoWait | If specified, the script will not wait for the online flash background task to finish. If the user reboots the PC during the online flash, the update will complete only after reboot. |
Notes
- Requires HP BIOS.
- Requires 64-bit PowerShell (not supported under 32-bit PowerShell).
- UEFI boot mode is required; legacy mode is not supported.
- This command requires elevated privileges.
WinPE notes
- Use '-BitLocker ignore' when using this command in WinPE because BitLocker checks are not applicable in Windows PE.
- Requires that the WInPE image is built with the WinPE-SecureBootCmdlets.cab component.
