Is there a fix to avoid the high CPU load caused by the NAS power management driver? It uses 50% of my CPU constantly. I can kill the process manually but that's not a long-term solution. I run Windows 10 with newest version of NAS navigator 2.

I'm not aware of a NAS power management drive that gets installed in Windows 10 by any Buffalo device, what NAS do you have?
-
I have a LS210D.
The driver is this: C:\Program Files (x86)\BUFFALO\NASNAVI\nassvc.exe -Service_Execute -dcyc=290 -dto=5 -dluc=0 -dmin=1 -dmax=2 -dflc=0 -apc=0 -log=0 -pm=1 -pall=1 -phttp=0 -pbc=0 -ppro=0 -pcyc=150 -pmin=1 -pmax=2 -pflc=0
And the Task manager service is called NAS Power management service.

I hadn't noticed that before, probably because on the dozen or so systems that I have NAS Navigator installed on it's never been a CPU hog. Try uninstalling/reinstalling NAS Navigator. If you haven't done so, download the latest version from the Buffalo website.

Thank you, I will try that.
Update: Uninstalled the program and re-installed NAS navigator 2. Same high CPU load started again randomly.
I disabled now the service completely.

This also happens to me. Usually when my computer wakes from sleep

I have exactly this problem, too. Win10 1809, Buffalo NASnavi version 2.76.
The "NAS Power Management" service runs at 50% CPU on my laptop, draining the battery and causing the CPU fan to blow hard. I've set the service to Manual and stopped it, to see if it stays quiet now.

I understand this thread is over 2 years old, but has this problem been solved beyond the workaround of disabling the service? It happens to me a lot.
