Why would my laptop Bluetooth device monitor use 100% of one CPU with no bluetooth devices connected?

Asked by ETpro (34145 points ) December 22nd, 2012

Are there self-maintenance routines Bluetooth’s device manager does every few weeks that would draw enough processor time to use up 100% of the capacity of one of the cores on a multi-core processor? Or is somebody elsewhere in my area hooking into my bandwidth? How do you ensure your Bluetooth installation is sufficiently secure? Having never yet used it, I left the settings to the default that come with my Asus Notebook.

Possibly scanning the area for devices?

Personally, I have never had a use for the bluetooth on my laptop, and thus leave it off at all times. My mouse has it’s own USB receiver, my phone hooks up via US or wifi, I don’t use a headset, my printer is wifi…. basically useless to me.

“scanning the area for devices” That’s what I was thinkin’, but 100% of a CPU seems excessive.

Could be a dodgy driver that doesn’t let the CPU scheduler know its finished its bit.

@jerv, @dabbler & @Lightlyseared Thanks. Since I’m not currently using it I’ll just disable it till I have a reason for it to be on.

try to delete a “paired device”. Try to delete them all and see if its still using cpu resources..

@geoffreyfosson Thanks, and welcome to Fluther. But there don’t appear to be any Bluetooth devices to disconnect. I did check, and the machine is set to notify me whenever a Bluetooth enabled device tries to connect to it. The good news is I haven’t gotten that warning in a couple of months now.
