Hi, not sure you can my friend, because and I know as I had to get inside mine to shut it up,,,there are 4 of these little monsters inside a size forget the name as of now, but are like a smaller size then a AAA and do a 1.2 volts, of the 4 only 3 of them are insulated, odd huh, and there are two you can get at, however they are glued, pinched, and soldered inplace when I tried to remove one a laser shot out at me, no just kidding, but I nearly destroyed the mother board and power input plug trying to pop one out, the other two are under the touch control called the UPPER ORION, seriously that is written on the board,,,probably where they keep the lazer. no lazer, but it does read Upper Orion. if you need to turn it off or manual reset it, which is like a reset on a human using a screw driver and jabbing it sever times in the brain, in other words doing this works but it wont work properly after, on the end of the upper orion there is a lip that slightly goes over the lower batteries near the power input, lift up on this to bring it off of the power poles at the connect ports. WATCH FOR THAT LASER!!!
