not sure if your sis motherboard comes with manual, accidentally
unplugging any of those wires would cause massive brain haemorrhage
trying to figure out which wire goes where.
no point asking for technicians to perform such a minor task,
it's easy, just remove the battery, buy new ones and install, it's
not rocket science. 
which is why I said, if one doesn't have a manual & don't
wish to accidentally unplug any wires which could cause disaster,
then it best to seek professional help..
