My Dell Dimension 9200 PC with Vista Ultimate purchased in May 2007 also has a problem recovering from a low-power state (I call it a 'low-power state' because I'm not sure which it is - sleep, hybrid sleep, hibernation, standby, some unknown faulty low-power dysfunctional state, or whatever).
When the machine is set to automatically go into a low-power state (which is listed as being Sleep mode), about half the time it seems to go into a state from which it cannot recover without turning the PC off and then on again.
I do not believe that the low-power state to which I refer is 'Sleep'. When I put the PC into Sleep mode via the Start button, it runs through a set protocol ending with the power button flashing. The PC always recovers rapidly on mouse movement or keyboard button press, and so this must be the correct Sleep mode.
I wondered whether from reading the posts on this thread if the PC was going from Sleep into some other low-power state such as hibernation. However, when it is in this dysfunctional state, the power button remains lit.
Vista seems not be using Hibernation any more as a low-power state (as per the above post where Sleep is described as an improved low-power state with features of the old Standby and Hibernation). That said, it is possible to drill-down into the Power Options and find a reference to Hibernation. Question: in Hibernation, does the PC power button turn off, or does it remain lit?
The dysfunctional power-state that I seem to be getting on my Dell PC seems to be a bad version of Hibernation from which recovery cannot occur other than with turning the PC off. I have all the current Vista updates installed as at 14 October 2007.
Along with this low-power state problem I have had another one in particular with Sleep mode which I have documented in the thread at
http://www.vistax64.com/vista-netwo...-mode-internet-connectivity-issue-solved.html
which was a loss of my ethernet connection to my internet modem-router when coming out of Sleep mode. That has now been solved, but the two problems together have driven me crazy.
Does anyone have a suggestion on how I might solve the this low-power state problem??
