Hi! It's a real pleasure to discover this post! So many times I try to find the solution to this lock on my computer. I don't understand why the BIOS is locked because I made Bios updates before but after this release, no more possible.
System Disable: 33D3DABC0974B8DE
Service tag: JSBJXQ2
Try each of the passwords 2-3 times using NEW INSTRUCTIONS, then proceed with OLD instructions if password still remain.
NEW Instructions:
- Reboot or power-on computer.
- Enter calculated password, press and hold left CTRL key down, press ENTER key twice (CTRL-ENTER-ENTER).
IMPORTANT: Give it at least 3 tries before continuing with old instructions, as some newer models require this alternate procedure to properly clear the system passwords.
OLD Instructions:
- Reboot or power-on computer.
- Enter calculated password and press ENTER key.
