I have just completed a clean install of XP on my Compaq Presario 2500 laptop, and installed SP 2 and 3. Before this I was able to hibernate, now I cannot. Power Options does not have a hibernate button at all, and does not give either Hibernate
or Stand By, as options for what is to happen when I close the lid. The turn off button on the start menu initially had Stand By grayed out, and Shut Down and Restart live, with no hibernate button. I have since done a registry edit sourced from
support.microsoft which has put a hibernate key in front of the Stand By key, but it is still grayed out. I have seen a mention of a possible problem with ACPI implementation with a clean install. Could this be the cause, and if so, how to fix
it. The installation disk was supplied with the computer when purchased. Can anyone help please. Grace Bragg
