I am no longer getting the blue LED 3x flash, so I guess the battery is perhaps taking on a little power ... but I'm still stuck at "Low Battery. Please Charge."
I just switched USB cables. The one I just plugged in has a snugger fit on the M92 end -- fingers crossed.
EDIT: Hours later, orange LED still on. With the other cable it would go out after a little while, but not with this one. I'm inclined to take this as a positive sign. We'll see ...
EDIT 2: Right after I posted the EDIT above, the orange light went out.
EDIT 3: M92 frozen solid on "Low battery" screen. I won't be able to open the unit until I get my new screwdriver, which might happen by the weekend.
Pressing 'Reset' has no effect.
Because the thing is frozen (like before) I have serious doubts that swapping batteries will cause any change, but I'll give it a shot.
