Hi, Firstly, my apologies if this is the wrong place to post, please educate me. I have a HP EliteBook 840 G3 with passwd'd BIOS and BitLocker encrypted drive. I've been in touch with HP who have sent me a file - smc.bin which should clear the BIOS password and allow me to format and reinstall and OS. I've followed the instructions sent to me, at least those I could actually implement (see below) since I'm unable to boot the OS, which by the way is Win 7. I'm still trying to retrieve the encryption key but do not expect to get it any time soon. The data was already backed up so that's not important. The instructions below that are in bold are the parts I've followed, sadly, the mode didn't switch to clear admin passwd. Any suggestions would be helpful. I know @Mazzif is a bit of an expert at such things but any suggestions would be great. If I have to replace the BIOS chip or try re-programming the existing chip then so be it. [These are the destruction's HP sent to me with the smc.bin file] (Important!) If this notebook uses drive encryption, such as BitLocker, to encrypt the data on its drives, this process will reset the embedded security and make the data unusable. Remove any encryption BEFORE proceeding with this process. Please find attached the SMC.bin file. Use the instructions below to clear the BIOS password: PLEASE MAKE SURE DATE AND TIME IS SET CORRECTLY BEFORE RUNNING THIS TOOL .Please make sure USB key is formatted to FAT 32 and preferably on a blank drive. Please follow these steps to clear BIOS password: Save the attached file with this e-mail to the root of the USB key as SMC.BIN and insert to the system (or save the file to the root of drive D: HP_TOOLS) - Press (Windows Key + Arrow UP Key + Arrow Down Key) all keys at same time and turn on the system - Release all keys and press F10 at HP logo to go to F10 setup to (Reset BIOS security to factory default) SMC command failure reasons Wrong UUID is provided Try different brand and smaller size USB key USB key is not formatted FAT32 Make sure to use USB 2.0 port and not USB 3.0 port on notebooks that have both types of ports. BIOS ,date and time should be current and updated. Use hard drive method by using HP_TOOL partition, if there is no HP_ tools partition, it can be created in either of 2 ways: or manually creating the partition as follows: 1. Use a partition tool like Partition Magic to create a partition on a local hard drive that has a System partition with the following characteristics. Partition type: FAT32 Partition size: 2 GB Volume name: HP_TOOLS 2. In the new partition, create a folder called HEWLETT-PACKARD. Then copy the SMC.bin file to the root directory of the newly created HP_TOOLS partition.
