ProBook 450 with high CPU usage

[JK80]

I still believe it's a driver problem, because if I deactivate the Conexant Audio Driver, system usage goes down immediately.

I think, HP should provide some updated drivers, which solve the problem, as soon as possible. Or if it#s a problem, which can be solved with a bios update, they should provide one. And in the meantime, some mod can maybe give us some feedback, if there is any progress with this problem.

Now there are many people, which have this problem, that it can't be coincidence. Maybe it's only a problem, which happens only in specific combinations (CPU, RAM, SSD / HDD -Combination).

I hope the problem will be solved in the near future, because it's really annoying.

I have noticed the same thing of @DaSwedishMan, if I go in standby and then I resume from it the CPU usage goes to normal values (less than 1% for System process), but I hope that they found a much better solution to fix that!! As he said it is really annoying to watch the task manager everytime the pc starts!

However (if it can be usefull) my laptop has i7-8550u, 16GB of ram, 512GB SSD, Windows 10 home and Nvidia GeForce 930MX (laptop model is 2UB65EA)

Hi. I join the club with similar symptoms in my ProBook 450.

Quoted is what helps temporarily. I keep that application window (no Idea what it's for!) open and clik rescan symbol in the upper right corner when needed.

I got a new audio driver date 1/8/18  version  9.0.183.0  a few days ago. Never checked for this problem though, as 

I haven't noticed any problems

Where did you get the driver from? HP or The Microsoft Update Catalog?

I've just updated driver through Windows Update (from Device Manager at Conexant Audio Item, click Update driver), not from HP. Now, I have same version as Ken1943. I'm curious if it helps.

Hello,

for me a clean boot "solved" the problem. I still have to find the process or service which occours this, but it looks like that it is maybe not a driver problem...

@chocholous and @Ken1943: Which model do you have? My Probook 450 don't get's any newer Versions than "9.0.180.10" for my ProBook 450 G5.
