Arc 4 Locked Up (I thought)

[georget98]

I was trying to remember if removing the battery would reset the switch lock. So I turned on the lock, then untwisted the battery enough to disconnect it. I tightened it right back up and pressed the button while the light was "booting up," probably about the moment the Ready for Service sequence would have started. The light turned on and I discovered I couldn't turn it off. /ubbthreads/images/graemlins/ooo.gif

Never mind... I figured it out. /ubbthreads/images/graemlins/ohgeez.gif It appears the light saw the switch pressed during startup and decided the switch was broken and started up in "broken switch" mode. I remember Peter telling us the likely failure mode for the switch is closed and if the light detects this it can still be turned on and off by twisting the battery.

It is very easy to reproduce actually, you just have to hold down the switch for a while when the light is first booting up.

(unscrewing the battery compartment resets it, and the switch works properly again)
