The Old Smack The HP 41C Trick - Jim L - 02-09-2001

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?

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

Tighten the screws, do not strip.

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.

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).
