    there is one way of doing it through terminal -

    1. Open Terminal (located at /Applications/Utilities/).

    2. Type: top

    3. Press Return to open the top utility in the Terminal window. Two rows near the top of the window, "PhysMem:" and "VM:" indicate overall physical RAM and virtual memory usage, respectively. The two columns on the right, "RSIZE" and "VSIZE" offer memory usage information per application. RSIZE indicates the amount of physical RAM in use by the application or process, in megabytes ("M") or kilobytes ("K"). VSIZE indicates the amount of virtual memory Mac OS X has assigned for this process or application, in megabytes ("M") or gigabytes ("G").

    4. When you are finished reviewing the information, press the
    Q key to exit top.

    or the simple way is to use istatpro found here -

    iStat pro is the ultimate system monitoring widget, consisting of nine sections which can be shown or hidden.

    It features highly detailed information on CPUs (up to 8 cores), memory, hard drives, IP and external IP, bandwidth, battery, wireless keyboard and mouse battery, uptime, temperatures, and fans. You'll know exactly what's going on inside your Mac!

    Go to this Link and it'll work for u:

Hi dv4242

Here is how to do it :

  1. First open the Activity Monitor
  2. Right Click (or click and hold, or CTRL click) on the Activity Monitor icon in the dock and select ‘Keep in Dock’ (if it’s not already there)
  3. Right click on the Activity Monitor icon again and select the ‘dock icons’ menu
  4. From the ‘dock icons’ menu select the ‘Show CPU Usage’ item
  5. There you have it, a nice little visual representation of your CPU usage, it is even separated by cores (if applicable)
Hope that helps
Have a nice weekend

Anything that requires more activity from your CPU will shorten the battery charge. It is eating power. I am not sure about "Magician".

I am not really sure if this caused by the fan performance, but I can confirm that my laptop dell inspiron 1420 is very hot after running about 1 hours.. and often my CPU usage reach 100% when I use Vista...

First, I appreciate the details provided in your question. Thanks!
The specification of your laptop are fine and enough to run and support Vista. It is true that greater number of processes and CPU usage causes, but normally the machine can handle it well if it gets proper ventilation.
Laptop heating issue generally occurs due to fan failure, which may damage the system, if not checked properly. Another cause of overheating is the dust present inside the laptop, which clogs the fan and heatsink. I suggest that you should get you laptop checked by a professional for servicing (if required). I believe immediate action is required to prevent any damage to your machine and data.

Hope it Helps! Let me know if i could be of any further assistance.

Normal operating temperature of Apple Ibook Power supply ?

Use the free App called iStat Pro to monitor ALL temperatures. Give your Mac some air (literally)
There is a big difference between CPU Temp and, for example Enclosure.
You also may have a very high CPU usage for a while.
Check if your fans are running high I.E 6000 Rpm

Mac book Pro high CPU usage with nothing running

I would worry the fan is not fulty, you may want to get apple to check the pc for you but they normaly charge a diagnostic fee.
The other possibility is your sitting it to close to a wall or your sitting it on the transformer (though i doubt it)
The incriment in system resorces would be in responce to the build up in heat but i expect thats only a short lived spike.
make sure you have it in a clean well vaccumed area away from carpet or other dust collecting surfaces.
if thats unavoidable then stick a vaccume to the air vents to clean any buildup you would be surprised what i have seen in dust buld up in fans after 4 months running a laptop on car seats uni benches & other less clean surfaces.

My Macbook fan keeps running

There may be high CPU usage by some program. It would be normal for the fan to run if the CPU usage is high. Check the Activity Monitor (found in utilities) to see if something odd is going on.

I had a problem where iPhoto quit working, and somehow was using 90%+ of the CPU. I could view the photos, but some operations did not work and the only way to exit was Force Quit. I had to remove and reload iPhoto.
