Trying to use the BT mouse on the Toshiba S855-5378 without the laptop battery resulted in periodic mouse freezes after several minutes of use, usually a second or so after a popup notification of "low BT mouse battery" (batteries were new).  I have similar errors in syslog that altimonin posted.

Title:
  12.10 Bluetooth Battery Indicator Interferes with Bluetooth Mouse
  Moves

Status in Gnome Powermanager:
  New
Status in indicator-power package in Ubuntu:
  Confirmed

Bug description:
   A fully updated (Jan 11, 2013) Ubuntu 12.10 allows the bluetooth
  mouse to "connect" but fails to move the cursor.  The bluetooth
  battery indicator is created and works.

   If bluetooth  is turned on just before mouse connection is attempted (before the battery  indicator shows the mouse battery), sometimes there is mouse cursor  movement for a fraction of a second.  One time, a mouse onnection succeeded,  and at that time, the battery indicator for the mouse no longer reported the current battery state (switching batteries of different charges no longer accurately indicated the battery charge).  
  hcidump reports the mouse moves, but the cursor does nothing, nor do clicks.

    ** The mouse does work if the battery indicator is killed soon after
  boot before bluetooth is turned on.**

    Taking a wild guess, the bluetooth battery indicator handler is not
  re-queueing the mouse moves it sees while looking for the battery
  info. Additionally, the mouse handler, when it rarely gets a position
  before the battery handler is not re-queuing the battery messages.

   Equipment:
   HP V3000, with Nvidia 6150 running driver version 304.51, root on 8G usb.
   Bus 002 Device 002: ID 03f0:171d Hewlett-Packard Bluetooth 2.0 Interface
  [Broadcom BCM2045], Generic Bluetooth mouse
   Broadcom 4311 wireless running the b43 driver with the firmware supplied
  from package firmware-b43-installer.
   xorg.conf file was originally absent, but copying one from my 12.04
  installation made no difference.
