How do I activate the 2nd core on my D620?
Looking for some help. I have a Latitude D620 T2400 with a dual core processor (1.83Ghz and 1 Gigabyte of ram) that was given to me by my work IT group. However, I noticed that our IT group has the processor setup to only have one core active (the 2nd core has been deactivated). I asked them about this and they confirm that they have deactivated the 2nd core due to possible conflicts with some of our legacy systems. Our IT group will not tell me how to activate the 2nd core, but claim that if I look online I should be able to find info on how to do it.
I have looked, and have not found anything obvious. Can anyone tell me how to activate the 2nd core so I can take full advantage of this notebook's dual core processor? Any assistance would be greatly appreciated.
I am running Windows XP Professional with SP2
PS - I have looked in the BIOS, but nothing seems obvious as to how to do this.
- Look in the device manager under Computer. You'll likely see "APIC Uniprocessor PC". That's what you'll need to change (you will need admin privileges to do it).
BACK UP WHAT YOU CANNOT AFFORD TO LOSE. While XP allows you to change the computer type without reloading the OS, unlike earlier versions of Windows, things CAN go wrong. notladstyle

Boot to the BIOS and see if there is a setting for dual core operation in there.singlemalt

Everyone - Thanks for the more detailed info. However, here is more info on exactly what I see when I go to the Device Manager and expand "Computer":
1. When I go to Device manager and click + on computer, the only option I get is "Advanced Configuration and Power Interface (ACPI) PC".
2. If I double click that, go to driver, click update driver, tell Windows not to connect to Windows Update, select Install from a specific location, uncheck the boxes and select the don't search option - The next window has a box checked labeled "Show compatible hardware" and in the Model window I have 2 selections: there is a green check next to the first choice "Advanced configuration and Power Interface (ACPI) PC", and there is a green check next to the second choice "Standard PC" (green check standing for - this driver is digitally signed).
3. Those are the only choices I have. I do not have anything that indicates or says multiprocessor.
Anymore comments or suggestions are greatly appreciated.singlemalt

Additionally, I have thoroughly went through the BIOS, and could find nothing that looked like it would help enable the 2nd core. Everything in the BIOS that refers to dual core looks fine and/or is enabled.For example - The BIOS is reporting that dual cores are present. Also, under the performance tab, the dual core option there is enabled. Couldn't find anything else that looked applicable.

Also, I do not have a Windows XP Pro installation disk. So I don't think I can change my ACPI HAL to the multiprocessor HAL.notladstyle

Google CPUZ - its free - Download it, unzip, and run it.
Look in the area that is circled RED in this image - it should say 2 cores and 2 threads.
