X1 Carbon Touch - Ricoh Card Reader causes high CPU utilization

2014-01-10, 15:07 PM

I have an X1 Carbon Touch i7 16 GB RAM Model 3443CTO, up-to-date drivers and BIOS, running Windows 8.1. Since I received the device, my Ricoh Card reader would cause my CPU utlization to be elevated 70-80%, thus causing my fan to kick-in at high speed, causing a lot of noice.

 

This would occur at random times, even when not have any media inserted into the reader. Truthfully, the reader has never been used (but I'd like to begin using it). Rebooting my machine would not resolve the issue, as CPU utilization would be elevated after the reboot.

 

I was able to determine the Ricoh Car dReader caused the problem via process monitoring and Device Manager. To resolve the issue, I have disabled the Ricoh Card Reader in Device Manager, and my CPU utilization immediately falls to 1-2%.

 

I have had my motherboard and speakers replaced 3 times, and I believe I have other hardware issues with USB. I'm wondering if there are significant problems with my hardware or if these are a series of coincidences.

 

Has anyone else experienced these issues? See attached image for the disabled hardware in Device Manager.Capture.PNGCapture2.PNG

it sounds like you have a few things hardware related that could be you issue... i would check for any bent prongs on your mobo or your usb card/combo card... seems pretty strange.

 

also how the heck do you have an x1 carbon/carbon touch wih 16gb of ram? maybe that was a typo?

Or possibly related to the same symptoms found on the X220 and X230:

Try uninstalling the driver and letting Windows find one for you.

I don't work for Lenovo. I'm a crazy volunteer!

Maybe this is why Lenovo got rid of the SD Card reader in the "new" X1 Carbon.
