Wiimote bricked??

[getup2k]

So I'm fairly new to this (started a couple of weeks ago) and today tried syncing up my (official, vanilla) wiimote to the toshiba stack. It synced, as I could see the 'green arrow' but then this disappeared after a few seconds along with the lights on my controller. I checked dolphin and the controller wouldnt connect. And tried again with the stack with the red synch button, but no. So I thought the batteries ran out. However after replacing the batteries (they are definitely new ones) the controller doesnt even flash when buttons pressed. I double checked dolphin to no avail and even removed the controller settings from the stack but nothing. It seems bricked.. is that even possible on a Wiimote? Anyway any advice is greatly appreciated!
