Default Repair help for novice

I would like to know if anyone can lead me somewhere to repair this handheld green laser. It is 6 1/2" long & takes a US18650GR battery. According to what I have found online the battery voltage is ok but the laser does not work. There is a circle near the front which says "RUNFA" I'll try to enclose a pic. Thank you,

First of all, don't look down the barrel. The laser may not be putting out green light, but it could be putting out dangerous amounts of IR light that you can't see very well, but is still harmful.

See if you can unscrew the head from the body. That's the first step in repairing those lasers if it's not a battery problem. Even so, I've never been able to dismantle the focusable host I have, and it might be hard for you with that one. Then you can see about replacing the module or doing some tests.
