Update to my own issue:
I believe this problem has recently resolved itself. For those reading who
have had similar difficulties but found no solutions, the problem disappeared
once I had installed the Windows Vista Service Pack 1 into each notebook's
operating system.
For one of the notebooks, though, doing this was difficult; the Windows
Update feature failed each of multiple times to install the service pack into
the operating system. For that machine, I had to download the service pack
as a stand-alone installer and integrate it manually that way. If anyone
else faces that issue, too, the primary stand-alone installer can be obtained
at

Hopefully, those facing similar problems with the Windows Vista power plans
will find the solution similarly simple.
