Unable to turn on bluetooth on my lenovo ideapad U310 using ubuntu 14.04

I'm a new linux user and I don't really understand the replies to similar queries. The toggle in the bluetooth settings won't turn on at all.

First, check out if you have the Bluetooth LKM (Linux Kernel Module) enabled.

sudo lsmod | grep bluetooth

If you don't, try this.

sudo insmod bluetooth

If this fails, you'll have to recompile your kernel to add Bluetooth support (unlikely, since Ubuntu has a rather good hardware detection). If th bluetooth LKM successfully loads, try troubleshooting the issue with bluetoothctl

sudo apt-get install bluez

Then

[bluetooth]# list
[Controllers list]
[bluetooth]# select [controller]
[bluetooth]# devices

That should give you a base for troubleshooting. Also, check dmesg to see if there's any issue with the LKM on boot-up.

Edit: removed yum command.

I've got this issue in Cinnamon on Mint 17 (14.04 based), both with Network Manager and Bluetooth Manager.

I've successfully used the same hardware combo (ThinkPad T530 / Nokia E52) with Mint 14 (based on 12.10) via Network Manager for DUN to T-Mobile UMTS.

Now, I've connected it with a manual setup as in here: created BluetoothDialup chat and peers scripts, and modified rfcomm.conf to my specific options.

Then i used:

sudo rfcomm connect rfcomm0 my-phone-MAC my-phone-Channel pon BluetoothDialup

It then works, if one can point routes and dns to the right direction. However, functionality that worked out of the box in 12.10 is broken.
