Roger K. Wells,
On my older Think Pad I had a similar problem with devices, such as WLAN and Bluetooth, shutting off and not showing up in Linux for no apparent reason. Every so often I would have to ensure that the BIOS settings had the device enabled, that other Operating Systems on the computer didn't have the device disabled, and that I didn't accidentally hit the physical switch on the computer disabling the device. I found that most times the other operating system (Windows XP at the time) had the device disabled for an unknown reason and that re-enabling the device in the other operating system allowed the device to properly operate in Linux.

After using a bluetooth mouse for a couple of weeks on:
[root@rwells-cts ~]# uname -a Linux rwells-cts 2.6.18-128.7.1.el5.centos.plus #1 SMP Mon Aug 24 10:03:38 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
the machine is a Lenovo laptop, X200
today after booting (and re-booting) not even the bluetooth led lights up (it did so immediately after installing CentOS), there is no bluetooth icon on the gnome task panel hcitool finds nothing, re-installing gnome-bluetooth has no effect, etc.....
Any ideas on what to do next will be appreciated.
thanks,
