It looks you've been hard at work fixing up Lenovo's inhibited BIOS.
I have a Y650 and i have a friend who just got a new Y550. His bios is newer than mine (i got the Y650 right when it came out), and has an option to disable the extremely annoying AC adapter removal beep, and it generally seems more stable. Are these BIOS's similar enough where I can load up the Y550 bios on mine? We both have P8700 processors with nvidia graphics cards. Any ideas on where I can find a BIOS file to flash?
Thanks for your help with the VT enabling, we all appreciate it.

I just wanted to thank you.
I followed your guide and was able to get hardware virtualization (Intel VT) enabled on my Y650.
A side note for anybody else with a Y650, follow middleton's guide (follow the link above). The only change I had to makes, was I had to add the lines. Not edit, because they where not already there.
My machine is:
Model: Ideapad Y650-55U
BIOs Version: 2.01

You don't need to flash new BIOS. Use the procedure for Y550 (I gave link to it in my first post). You have to change the following BIOS variables: (0372) and (0375). And of course your CPU must support VT.

What if I see 0372 and not 0375 (or the reverse)? I checked the BIOS, it shows 1.04. I looked for the two numbers as shown in the Y550 post and only found one of the two. Do I need to add the other in? Or, do I need to change one or two numbers that differ from what is shown for the Y550 w/the same BIOS?

You should manually add the absent variable (0372 or 0375).
Guys! I can't understand why you periodically ask me the questions like this. I've written in the guide the following:
"if you cannot find variable then type it yourself".
English is not my native language. Maybe this phrase sounds ambiguously?

What you said (about adding things in if they did not exist) made sense. I simply wanted to confirm as I hadn't seen it mentioned for my exact model / firmware. As I don't have a 100% understanding of the similarities between the Y550 and Y650 BIOS I had wanted to be certain that I wouldn't risk anything by my actions before I actually took them.
I only had the 0375 figure in my dump file (no 0372). I only updated the 0375 when I first attempted to follow your directions/post. I then came and posted my question here. While I waited for an answer, I booted the system as normal and ran XP Mode, VMWare VT-style, and everything worked (no "you don't have virtualization enabled" type errors). So, I am not certain what the "0372" is supposed to change but, for now, only changing the 0375 has moved me from being unable to use anything dependant on hardware virtualization to having full use of all such programs.
At this point, is it necessary (or at least smart) for me to go back in and create the 0372 entry in the BIOS txt file? Thanks for your help.
