Bluetooth Turned off and not recognized anymore.

Asked by curtis on 2012-06-28

Ubuntu us acting as if bluetooth no longer exists on my HP Folio 13. It worked since I got it but recently I turned it off to save power and after restarting it is no longer there. Is there any way to issue a command to initialize it again or turn it on?

I have already tried sudo /etc/init.d/bluetooth restart and it didn't work. Here is what I am getting from dmesg:

 dmesg |grep -i blue

Can you give the output of:

lsb_release -a; uname -a

Thanks

here you go:

lsb_release
No LSB modules are available.

uname -a
Linux maverick 3.2.0-25-generic #40-Ubuntu SMP Wed May 23 20:30:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

ok and the output of:

cat /etc/lsb-release

Thanks

This must have been a hardware/motherboard problem. Read else were to completely power off the computer and unplug it from the external power source for 2 min. This should reset the motherboard and by association the bluetooth device.

Thanks for the help though
