I think I have finally resolved my Vista sleep problem. My solution path
was:
-my HP Pavilion Vista system did sleep properly between May 25th (when
I bought it) and June 13th; after that it began either not going to
sleep or not waking from sleep.
-on June 13th I had attempted to install software to run my HP Scanjet
3970 from a CD in drive E: I thought I had verified that the hardware
and software would run on Vista, but evidently I was wrong; the scanner
software appeared to partially install, but not completely; I
subsequently uninstalled the programs.
-I realized later that one artifact of the abortive installation
remained, a reference to a program called zzzhpsetup.exe
-I found it in the list of msconfig startup tab items. After I
unchecked it, and did a reboot, the sleep function started to work ok.
-zzzhpsetup did not show up in a full system search. Its msconfig
Startup Command column showed E:\Setup.exe and referenced
HKLM\SOFTWARE\Windows\CurrentVersion\Run in the registry; however, there
is no recognizable item for zzzhpsetup in RegEdit. Google searches
reveal almost nothing about such a program, although it seems to show up
in peoples' HJT logs. I will just leave this item unchecked in the
msconfig startup list. I would like to remove it from the listing
altogether, but have not found a way to do this (since it does not show
up in the registry).
-At this point, I have returned most of my Power Save options to the
default values and the machine is sleep and waking normally. Obviously I
don't have a cause and effect conclusion that zzzhpsetup was the source
of the sleep problem, but on circumstantial evidence, it seems likely.
Thoughts from anyone would be welcomed.
