I am trying to help someone that has a problem with a Dell 530 Inspiron using Vista that will not go into hibernation mode. The message that you get generally says that IDE Channel device driver will not allow computer to enter hibernation mode. At first I did some searching thinking this was a Vista problem but found some info that says this a hardware/motherboard/Dell problem. Others with this same machine are having the same problem based on some posts on the tech sites. Any helpful comments would be appreciated. TIA.
