Battery? Time to smash the computer and look for a new one? I got this one about two months ago, with the bike.
It's easy enough to check the batteries - spin the tire and see if the little icon indicating it's receiving a signal is pulsing. If not, replace the sensor battery.
I've found mine lasts around 6 months. May as well change both at the same time, since batteries come in packs of two. :-)
