Hey everyone,
I've a second-hand HP EliteBook 840 G3, and I’m trying to enable virtualization (VT-x) to run virtual machines. The issue is that the BIOS is locked with a password which I don’t know. Since this is a used device, I don’t have access to the original owner or any warranty/support options from HP.

I’ve already tried the following:

  • Disconnecting the main battery and CMOS cell for 20+ minutes (no reset happened).

  • Attempted to enable virtualization using Command Prompt and PowerShell (not possible without BIOS access).

  • Looked into common backdoor passwords or jumper reset options, but couldn’t find a reliable method for this model.

Does anyone know a working way to bypass or reset the BIOS password on this specific model? I only need access to the BIOS to enable virtualization. Any help would be greatly appreciated.

Thanks
