Microsoft doesn't supply them. Look for the driver cd that came with the laptop.
OR you had XP Home and installed XP Pro. That's easier to fix. Install the maker's os then slip in the XP Pro CD and upgrade the OS.
I just reformatted my laptop with WIndows XP Pro and now when I close the lid of the laptop it just stays on and doesn't go into standby mode. I went to the power options to try to change it but I don't even have the option to change it. It only has "do nothing" for "when I close the lid" Also, the standby is grayed out when I click start and then shut down. Am I missing a driver for this option or is it something else? Thanks.
