The Old Smack The HP 41C Trick



#2

I've often noticed that when I find a new 41C and first install the batteries and turn it on that nothing happens.

If I then smack it firmly but not too aggressively into the palm of my hand, it will very often spring to life. Is this a common experience? Is it understood or is it just strange luck?


#3

Pressing and/or gently twisting the case may improve the contact between internal connectors. Do it carefully!

#4

Tighten the screws, do not strip.

#5

More 41's die from breakage of the internal screw posts than any other cause. I suggest you find a different technique for starting yout 41.


#6

yes jim, at least give it a chance and type in (alpha)look; if you don't turn on i'm gonna have to smack you (alpha).
