Not strictly a on-subject topic but knowing you lot are hot on the latest drivers...
If you're recently developed trouble with your PC not waking up when you bump the mouse (it stays sleeping), it's probably the process "Intel Dynamic Application Loader Host Interface" that is causing the problem. If that is killed, the mouse wakes my machine from sleep. If that process is running, the machine won't wake to a mouse/KB bump.
It took me a while to figure out via a process of elimination (glad my machine restarts fast!) but I'm pretty sure that's it. Earlier intel drivers are OK (I have tried 31.0.101.4577 and that's fine). The one that's causing me grief is the current one, 5382.
I've reported it to Intel.
