I have a problem with Windows 7 not sleeping.
PowerCfg -requests
says a "Legacy Kernel Caller" driver prevents the sleep mode. This is not very helpful or informative. How do I get more details about that object?
EDIT:
I found that
Powercfg -requestsoverride
is the best way of dealing with such misbehaving drivers and software.
The option -requestsoverride is not very well documented. MSDN doesn't mention NAME is case sensitive, and to remove a request from overrides list you give the option with blank REQUEST parameter.
powercfg -request
powercfg /requestoverride driver Legacy Kernel Caller
. It seems like it didn't do anything.
