On Windows the system wakes up when connected or disconnected from an AC adapter.
Does it? I could sweat my work laptop (windows 10) doesn't , and I'm pretty sure I'd notice cause I sleep and move it a lot during a working day.
Is it a windows 11 thing? Or something to do with the so-called "hybrid sleep / hybrid boot"? (Pretty sure that's disabled by corporate, and for friends and family I always disable that when their laptop goes in a boot crash loop). Does BitLocker matter ?
Some key points regarding Proxmox:
For reference, my oldest Proxmox server is a 2013 AMD dualcore 16GB DDR2 ram with VMs on LVMthin on a single SSD, with legacy VM doing mdraid of 3 HDDs using hardware passthrough. Performance is still OK, the overhead from Proxmox is negligible compared to strain from the actual workloads
