What CPU do you have?  Not all support TurboBoost.

i5-2520M

That CPU does support TB.  Who did the installation of Windows 7 Enterprise?  It sounds like it may not have been done properly.

It would have to have been - unless the organization that bought the system has Dell custom pre-image the system, it would not have come with Enterprise.

It sounds like they loaded an Enterprise image (which you may in fact not be licensed for) incorrectly - or that the image wasn't built properly for that model system.

You won't be able to contact Dell until you have the current, registered owner transfer the system into your name.  Your best bet is to contact the seller from whom you purchased the system.  Very likely, you're going to need to purchase a copy of Windows for your use, and load it - unless you want to use Vista Basic, which is what the license for the system includes.

Should i contact Dell and Microsoft in Israel?

My friend did i think. He got this laptop subsidised from university. What is strange is that on label it has Windows Vista product key and not Enterprise. I can as well see Windows Vista Basic logo on the chassis.

Does that mean laptop came with Windows Vista but was upgraded to Enterprise?

Well, service tag was transferred on my name already to my country.

When not plugged into the wall many laptops run in slow mode to save battery power.

Thats why speedswitch XP was made a while back.

Its amazing to me that they don't let you set speed to MAX regardless of Battery or AC but I think it has

to do with ENERGY STAR requirements.

Why would i need to use Vista DVD with recovery partition? Partition already has built-in Vista installation source. At least this is how it was on my old HP Pavilion.

I need to know what is responsible for Turbo Boost in Windows. It can't be Windows because drivers are from DELL and Intel so it must be drivers. Maybe i should uninstall and reinstall them and also reset BIOS to factory defaults.

I think i have DELL recovery partition on hard drive, with Vista obviously. I don't know how to check this and how to acivate install. By the way, i can install Vista and then Enterprise on it because i assume i already have license key to Enterprise since i use it now.

But why you think reinstall would help? I already managed everything, restored, copied which took 1 day. Not sure if i must reinstall.

If there's a recovery partition, you're going to need a Vista DVD to use it - installing 7 Ent. would have deactivated it  (or wiped it out).  If you received a separate license key with the system (which is unlikely) you may  be able to use Enterprise.  More likely, you did not.

There's no reason TurboBoost shouldn't work -- IF the install was done correctly.  

That's fine - next step would be a clean install of a version of Windows for which you're licensed.  Unless your university covers Enterprise for students (in which case you should qualify to get a disc from your IT group), you'll need to contact Dell for a Vista Basic install disc, or purchase a new copy of Windows.

You mean they disable Turbo Boost in my model?

Let me tell yoo something weird. SpeedStep was disabled and Turbo Boost enabled, but it was disable in Windows. After i enabled SpeedStep in BIOS, Turbo Boost worked in Windows but CPU was working constantly on 700Mhz no matter what and was very slow especially when i put it through stress test. CPU almost did not respond.

As i said, CPU was working at 700Mhz always no matter what even if it was not overheating.
