I got a laser pointer (from the local icecream man, interesting) and when I opened it up, the circuit board inside was completely different from the one on your website. I couldn't figure out where to connect the power. Should I post a picture?

You should be able to easily trace where the battery was connected.
Look for a place where the circuit board connects to the case (usually
at the business end of the laser, where a metal part is crimped to the case).
This will be one connection, probably the positive side of the battery.
Now look for a spring that presses against the batteries. This is probably
the negative side.
Arrange the original batteries in series, with a wire from each terminal.
Now connect those wires to the places you have identified as possible
connection points. Then push the button, and see if the laser lights up.
Now you can see if you can place one of the wires ahead of the switch,
so you don't need to use the switch. Be careful, however, because if you
connect the battery ahead of the tiny surface mount current limiting resistor,
you will put the full power of the batteries into the laser, which will
Also, be careful to ground your body before touching the circuit board.
Tiny amounts of static electricity from your body can destroy the laser.
You might not even feel the spark.
