    I upgraded to dual-core in laptop over a week ago and while it shows 2 processors in Device Manager and I do see benefits from dual-core my sidebar gadget shows both cores at work and i can set which core runs processes in Task Manager but ive been told I may have to change the HAL...

    ive checked in Devmgmt and it says ACPI 86x Based-PC (in Vista) theres no mention of Multiprocessor PC ... I dunno if this is right or not..

    Task manager shows both cores

    what do I do???


    THANKS

    Who is what is telling you to change the HAL, the HAL for a Windows based PC just comes down to basically motherboard drivers.

    From the sounds of it, nothing is wrong, or broken so could you elaborate please.

    Thank you paulb100

    crjdriver said that if i hadn't re-installed Windows on my laptop after installing the dual-core processor that it may still be running under old HAL ...??

    Like I say it shows that its working fine , I think MultiProcessor under computer in dvmgmt is just a Windows XP thing not Vista

    thanks ...

    In Task Manager, on the Performance tab, do you see TWO graphs for CPU Usage history, or just one? If only one, check View | CPU History, and see if you can set it to one graph per CPU. If you can, you should be good to go. If you can't, then you will need to update the HAL.DLL file.

    For Vista, start msconfig, goto boot tab, click Advanced Options. If Number of processors shows only one, uncheck it if checked, then check Detect HAL. Ok back to desktop and reboot.

    You can then go back into msconfig, goto boot tab, click Advanced Options, and Number of processors should be showing 2. Check the box, uncheck detect HAL, OK this screen, then check Make all boot settings permanent (This will make your current configuration Normal, so if you are currently using msconfig to disable any boot items/services, you will not be able to click Normal Startup to restore them)

    HTH
