Windows 7: Question about VT and Battery Life

Question about VT and Battery Life

I want to enable Virtualization Tech on my computer to run XP Mode.

However, the VT mode is currently off in my BIOS. I want to know what the effects of enabling it will be.

Will turning VT on decrease my battery life?
Was there a reason why it is defaulting to being off in the BIOS?

My biggest concern is battery life. If i turn on VT and it drains the battery faster, then I will go without VT. Does anyone have any experience in this?

The effect on battery life, I am not sure. But by default it is off since it is something that until xp mode the mainstream user did not use.

The only way to check the battery life difference is to test it out.

The VT itself probably wont make much of a difference, but if you are actively running XPM then that will obviously take some power to operate, therefore decreasing battery performance.

Yea. I was only concerned with "if i enable this option, will it lower my battery life". I know that running XPM will lower my battery, im just talking about, if I enable the option and never use it, will my battery drop

Of course. If you open the VT mode in BIOS, the battery will last less time than before.
But you can plug the power outlet to avoid this happen. Why do you want to use the virtualization Tech on battery. If you insist on it, you must buy a new bigger battery such as ibm thinkpad z60t 2511 battery has 4400 mAh to support it.

Laptop - Total Noob - Battery Life Question
Hi All! I just got a new laptop. I went through the suggested 'break-in' cycle with the battery; that is, letting it drain, charging, letting it drain, etc. So the question is this: Does running the laptop on AC power shorten the life of the battery? This may sound stupid, but I have other...
