Tip: Enabling VMX support for Dell Latitude E6400

Share this:

Here’s a quick tip if you’ve been trying to enable Virtualization support for the Dell Latitude E6400 and wasn’t able to. If you’re like me, you’d probably enabled all the settings available under the Virtualization section of the BIOS. Well, apparently, that’s a BIG mistake.

What you need to set is actually the following:-

  • Virtualization support – ON
  • VT for Direct I/O Access – ON
  • Trusted Execution – OFF

Where I got it wrong was to also enable the Trusted Execution to ON as well! Also important is to power down your machine right after the BIOS settings are configured. This changes only takes effect after a full power down.

That’s it! Now go ahead and enjoy the cool capabilities of virtualization!

    Cool. It’s one nice notebook especially on the latest BIOS update that resolves those fan speed issues. BTW, does your notebook come with the keyboard lights?

    Thank you for the “heads up”. Trusted Execution was enabled by default, so I had expected it to be required. Your advice was great!
