high cpu usage when idle / x230

Hi all,

 

I have an i5 x230, win8 pro installed on a crucial m4 msata ssd, 16gb of ram. I lately noticed a sharp drop in battery life. I believe this is due by high cpu utilization when idle, which I see from task manager, and shows the System process hovering above 30% cpu utilization. This goes down when I restart, but comes up again after a while, possibly when coming back from sleep.

 

Does anyone have any idea about this? I tried to search the knowledge base a bit, but nothing came up.

 

Thanks!

It could be the auto-cleanup maintenance process from windows 8, hate that thing.

Hello,

 

Perhaps the following message thread will help: Ricoh Card Reader use 25% CPU

Indeed it was risdxc64.sys; I used process explorer to find out. I uninstalled the win 8 driver, and installed back the win 7 driver, and CPU usage is normalized.

 

Thanks for pointing in the right direction!
