    so, a few years back i read a magazine that said to change the type of computer in device manager to standard pc because it made the computer run a little better or faster.

    so now i've got my laptop and i've noticed it getting slower and thought that i would do this... VERY BAD MOVE!!!

    i can still boot windows and everything - it meant that i had to let the computer reinstall all of the drivers for my hardware - but i have noticed in the device manager now that there are two instances of 'standard pc', there is also a new section titled 'other devices' with about 15 devices that seem to have no driver for them - some mention 'ISA' so i am guessing that changing to standard pc means that windows thinks my laptop is now a desktop pc with ISA slots???

    i find that when i put my laptop lid down the thing shuts down, when i press the power button it turns off straight away (doesn't even shut down!). i had had the laptop configured for ages to do nothing when i closed the lid and give me shut down options when i pressed the power button. i look in power options and i can only cinfigure the monitor screen and hard disk power off options - every other option is not available. when i do bring up the shut down options i can no longer choose standby.

    i have also realised that i can not turn on my wireless connection - i've tried all sorts to get it to work with no avail! the laptop is an acer ferrari and when i call up the manager app it says that bluetooth and wireless are not present (by the way i can still get the bluetooth button to work - correction - it starts up with the button on but if i turn it off it won't let me turn it on again). the emanager and presentation manager buttons on the laptops casing don't work either (i have to access them via software route).

    my questions are:

    1) is it possible that something is going on with the acer part of my system - with regards to the buttons and also the wireless and bluetooth?

    2) can i change my computer type back to 'acpi uniprocessor pc' (yes it is compatible) and will this solve all of my power option limitations/other device entries?

    3) have i got any of my suspicions right and is there anything i've missed?

    by the way - i really, really , really don't want to reinstall windows xp all over again because:

    1) it has taken me about 3 months and COUNTLESS hours to customise my system to a T (i was hoping to get it perfect and then backup an image so i have a better 'starting block' in the future if i reinstall the system)

    2) i haven't got the windows install discs on me because they are at another location, far away and i can't get them very easily at all - i do have an image to reinstall from however but it would take forever to recustomise everything again!

    every bit of help is a life saver - thank you in advance!!! even ideas are appreciated...

    Steve

    Did you try System Restore to a time before you changed everything?

    yep. already thought of that. it did nothing

    is there a way of doing something through the registry?
    could i act as windows when it installs itself the first time and install particular files through a command prompt? (just throwing out ideas if anyone knows how to do these things)

    Welcome to TSG....

    Do you have the recovery disks for this computer?

    What is the make and model number of the computer and some system specs would be great also?

    I know this is not what you want to hear, but you cannot change from "Standard PC" to "ACPI Uniprocessor PC" without reinstalling Windows.

    with regards to the comment from Frank4d and to notify everyone that this IS solvable (i should have done this a long time ago - sorry!)

    the answer is that i got my laptop working again!!! how:

    i copied the 'acpi uniprocessor pc' driver files from a friends laptop over to mine and restarted. it fooled my laptop into thinking that it was the computer (that it actually should be) and worked fine, just to make sure i then uninstalled relevant drivers so that it could find the hardware again and reinstall all drivers!

    woo hoo!!!!!

    thaks for your help guys! :)
