Microsoft Sculpt Touch Mouse bluetooth needs to be repaired

1)
$ lsb_release -a
No LSB modules are available.
Distributor ID: LinuxMint
Description: Linux Mint 17.1 Rebecca
Release: 17.1
Codename: rebecca
$ uname -a
Linux XXXXX 3.16.0-29-generic #39-Ubuntu SMP Tue Dec 16 20:54:13 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

2) I paired my bluetooth mouse (Microsoft Sculpt Touch Mouse) but it does not stay connected .
I need to repair it (shutdown it did not solve the problem).
I thought that the problem was fixed regarding this bug report : https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1094744
but actually I still have the problem.

I checked the pin-code-database.xml file :
$ grep '7C:1E:52:' /usr/share/gnome-bluetooth/pin-code-database.xml
 <device oui="7C:1E:52:" type="mouse" name="Microsoft Touch Mouse" pin="0000"/>

4) I expect my mouse to stay connected when I use it or even after I come back from a coffee break. (Please note, that previously I had another laptop with Ubuntu 14.10 and the mouse keeps connected.)

5) It happens always.

And my laptop is DELL Precision M3800.

I do not know if this is related but I tried an Apple Magic Trackpad and it stays connected only a few seconds.
I'd really like to use it with my Linux Mint.
