I am running a virtual 32 bit Windows 7 on a 64 bit Windows 7 host. Nightly at 11:10pm, prl_disp_service.exe wakes the system. This is a service; if I disable the service, or even set it to manual, Parallels cannot start, so that's not a solution. How can I prevent parallels from destroying my computer's sleep? Thanks.
This is definitely the problem: C:\Windows\system32>powercfg -waketimers Timer set by [PROCESS] \Device\HarddiskVolume1\Program Files (x86)\Parallels\Parallels Workstation\Application\prl_disp_service.exe expires at 5:53:29 AM on 8/9/2013. But why is it creating a wake timer?
Anybody? Bueller? Nobody? Well, okay, I've got a work-around. It cancels other wake-up timers also, but in Windows Control Panel, Power Options, Edit Plan Settings, Change Advanced Power Settings, expand "Sleep", expand "Allow wake timers" and set that to "Disable".
