If no password is set, this step completes with the first attempt.Loops through an array of known BIOS passwords stored in the script and uses the Dell Command Configure app (cctk.exe) to attempt to clear the BIOS password.Checks for an AC power connection and fails the installation if one is not present.The installation executes a script which does the following: The BIOS or firmware update is ready to install in the Software Center. A logged-in user can also choose to install from the Software Center in advance of the maintenance window just as they could with other Windows or application updates. The installation will begin automatically at the next maintenance window. Prompt from Software Center for required update Once the SCCM application is required, it is scheduled to install during the next maintenance window and any logged-in user is notified that an update is necessary.

If an update is found, a report file is generated which will trigger an already-deployed SCCM application to become required when the next Application Deployment Evaluation Cycle completes on its regular seven-day interval. The scheduled task silently executes Dell Command Update once per week to check with Dell for updates categorized as BIOS or firmware. I will detail the technical information later, but first let’s look at the process at a higher level. Installing BIOS and firmware updates from Dell while ignoring other Dell updates that may be available.Notifying logged-in users that a restart is required.Ensuring laptops have AC power connected.Handling systems where BitLocker encryption is in use.

Handling systems where a BIOS password has been set.

In addition to the previously stated goals, this process also addresses the following considerations: I designed a process where SCCM along with a scheduled task created using Group Policy will utilize the Dell Command Update application to detect and later install BIOS and firmware updates. Once implemented, this process should not require regular staff work especially for things like downloading update files, creating or updating deployments, and making changes based on new hardware models. My objective with this project was to build a self-sustaining, automated process using Microsoft Endpoint Configuration Manager (SCCM) that would update BIOS and firmware for Dell computers by downloading the content directly from Dell. Installation of BIOS and firmware updates has become more important than ever given recent security vulnerabilities such as Spectre and Meltdown. It also reflects the usage of a newer version of Dell Command Configure for newer devices that support it. The update was necessary as Dell changed the functionality of Dell Command Update beginning with version 3.
