Question about processor speed and HD size

Ok, I bought a 1501 and the system online said it was:

AMD 64 turion 2.0ghz.
80 GB HD

When I look in system properties, it said 786 mhz, I closed the properties down and opened it again and now it says 1.6 ghz. First, why does it change and second, why is it only showing 1.6 ghz when I have a 2.0ghz??

Also, I have a 80 GB HD and it says I only have 69.8 gb. Why is that? Partitions I do not know about? If it is partitions, how can I delete those?

 

Its part of the CPU technology, when you are in battery mode, the CPU clocks down to save more battery; or when you dont use the CPU heavily, it will clock down.

As for the HD, there is a recovery partition on the HD, and yes, you can delete it.

Yea if you're on battery, your CPU will clock itself to lower speeds to preserve the battery.

 

do all laptops do that?

 

As far as I know, most laptops do it.

Don't worry about it though, because when you run an application or a game or something that needs CPU power, your CPU will clock itself back up.

 

Yes, all mobile processors have that feature. Intel calls it Speedstep..AMD named it PowerNow. These days even desktop processors have this feature as well.

 

cool thanks

 

I was going to say, Celeron isnt. BUT when I was thinking, Dell isnt offering Celeron anymore, which is very "cool", hehe.

You can use a program like CPUz, which shows you your current CPU-clock. You can see that the CPU slows down when it hasn't much to do. At high load, it will speed up to its nominal clock.

With "Notebook Hardware Control" or "Speedstep XP", you can even adjust the "beahvior" of the CPU. So you can make it stay always at lowest or highest clock, or you can adjust it to use lowest clock at <20% load and highest clock above this value...This is normally controlled by Windows. Different energy management profiles have different settings for the CPU. I'm not sure why this can't be changed in Windows itself...
