Windows 7: Black screen after standby or sleep

I experienced the black screen syndrome for the first time yesterday. Everything was black except for a big old cursor that I could move around the screen.

Have they figured out the cause of the problem yet?

I am not interested in the Prevx "fix" since they don't know what the cause is. Don't you agree? I was wondering whether Microsoft has figured it out. Alternatively, if I could issue a shut down while the screen is dark that would be ok too.

That is the only fix that I've seen.
At work we occasionally get things to work with a System Restore or an update of video drivers.

In XP the cause for this was usually simple - either video drivers or hard drive problems.
Since then things have gotten more complicated - and the solution is therefore more complicated.
Registry issues and permission issues seem to get most of the blame for this - but the exact cause is not determined because of the vast number of things that could be involved (I think that the Prevx fix is permission based).

Hmmm, I wonder if the use of Subinacl could be a way of fixing this (if it's a permissions issue)? I'll have to give it a try at work with the next one we get in.

I downloaded and installed an earlier version of the Intel graphics driver from Dell's website. Maybe that will prevent the problem in the future.
