Bluetooth not turning on?

I have a Vaio VPCCW21FX with a brand new installed Ubuntu 13.10 and I'm trying to connect a Wedge Mobile keyboard. So I went into the system settings, bluetooth and tried to turn it on but as soon as I click on the switch, it stays on for 1 or 2 seconds and then it goes back to the off position automatically...is there any compatibility issue? What can I do?

Solution 1:

First Check the Output for rfkill list all. It will tell you about the issue. If it's fine use:

rfkill unblock bluetooth # to start bluetooth

and

rfkill block bluetooth # to stop bluetooth

It has already solved your issue. I just wanted to post an answer for future reference.

Solution 2:

First of all, check that your bluetooth was unlocked on rfkill.

sudo rfkill list

In case your bluetooth is Soft blocked you can unblock it by running the below command,

sudo rfkill unblock bluetooth

In case your bluetooth is Hard blocked,then try to find a hardware switch on your laptop to unblock it.
