Im trying to speed up an android emulator using VT-X but there is no VT-X options in my BIOS. Even worse, my BIOS is almost empty! There is only the change password, which way to boot, information and a few boot settings (there is only 7 options in my BIOS, all Enable/Disable and no 'advanced' tab or options). Does anybody know how I could show that option? I have a Acer 5755-9674 (SNID 13717259616) with an Intel i7-2670QM (it supports VT-x) and an Acer JV51_HR motherboard. I checked a lot of websites and Q & As but I just cant find an answer. Thanks in advance.

2I am not sure what you want us to tell you. Of the option is not located in the BIOS then it cannot be enabled.– RamhoundCommented Feb 22, 2014 at 18:10

Well, I'm kinda sure that my BIOS is 'cut down' or something. I never seen one BIOS with this little amount of options before. Maybe some options are hidden?– Snipe_and_SwipeCommented Feb 22, 2014 at 18:47

Its very likely based on what you describe the firmware has features that are disabled. Not much you can do about it though.– RamhoundCommented Feb 22, 2014 at 18:57

Definition of firmware: permanent software programmed into read-only memory. Isn't there ways to 'go around' it? I heard of it happening so does it actually exist?– Snipe_and_SwipeCommented Feb 23, 2014 at 0:51

Have your installed the Bios software from lenovo driver download? May be that could help.– LuckyCommented Jul 31, 2015 at 5:44

You can only use VT-x if both CPU and motherboard support it. A motherboard that doesn't support VT-x is sadly quite common for laptops.
Things you can try:
If you didn't do so already, check if VT-x isn't enabled already. Just because there's no option in the BIOS doesn't mean it's not enabled by default.
Visit Acer | Downloads, choose your notebook model or enter your serial number or SNID and search for a BIOS update.
You should find you SNID on a sticker below your laptop:
If that sticker got lost or became unreadable, you can use this tool (Windows only) to auto-detect your serial number.

It doesn't seem that there is a jv51_hr motherboard spec on the Acer website. I checked another version, an Aspire 5755-6678, and it seems that it doesnt have VT-X. Does that mean mine shouldn't have it too? Commented Feb 22, 2014 at 18:58

Oh, and I know that its probably not enabled because I tried to install the 'Hardware Accelerated Execution Manager' for Android SDK. Commented Feb 22, 2014 at 19:03

Don't search for the motherboard; search for your computer model. You should find your SNID on a sticker below your laptop. If that sticker got lost or became unreadable, use this tool to auto-detect your serial number. As for the 5755-6678, different models of the same series can be very similar in some aspects and very different in others.– DennisCommented Feb 22, 2014 at 19:04

I search my SNID (Aspire 5755-9674) everywhere but it almost seems that Acer doesn't have specs for it or something! On its website, it says there is no such things as a laptop 5755-9674 (I still have the sticker, so it's not the wrong one) and on Google there is only things about replacing batteries or replacing screens.

Newer Acer Laptops (I have the E5-571-58CG) and it came with Virtualization on by default. I think that it will become a standard to have it on in the not too distant future.
