The operation SetBiosPassword needs a reboot to be efective. After the first execution, all SetBiosPassword operations will fail even if the password is correct until the reboot. This can create a problem if you do multiple Manage-LenovoBiosSettings operations without rebooting between them. The method for checking if the password is correct is changed to trying to set a value with it's current value to try to avoid this situation

Some HP models return the config info with a space in front of them. Change to manage correctly this situation

Sorry for the long delay. The Lenovo side is now addressed differently in v2.3.0: on 2020+ ThinkPad and 2017+ ThinkCentre/ThinkStation systems, the script uses the Lenovo_WmiOpcodeInterface and authorizes the supervisor and SMP password checks via WmiOpcodePasswordAdmin, which is Lenovo's modern path for this. Legacy systems retain the documented firmware limitation. The HP portion (TrimStart on the asterisk-prefix check) is being handled separately via #11. Closing this as superseded; the v2.3.0 release overview covers the new opcode-interface approach. |
