HP-15LE: Anybody else see double key registrations? - BobVA - 11-12-2011 Just curious. Poked around a bit and didn't see this particular failure discussed (as opposed to the "clicks but didn't register" problem). On mine (about a month old) I'll sporadically get two "divide" inputs for one press of the divide key. Happens about one in 15 times on average. Calling HP tomorrow to see if I can get a replacement. (I seem to be facing down a general technology revolt - everything from my valve cover gaskets to computer RAM decided to pack up at once!)

Re: HP-15LE: Anybody else see double key registrations? - Michael de Estrada - 11-12-2011 What you are describing is commonly referred to as "repeating", and yes, I've noticed this behavior sporadically on my 15C LE. On mine it seems to affect all the keys, not just a particular one. It seems to occur only when I press the keys slowly, or use my thumbs. I doubt any replacement will solve this, as it's probably a software issue with debouncing. Edited: 12 Nov 2011, 6:06 p.m.
Re: HP-15LE: Anybody else see double key registrations? - Thomas Radtke - 11-12-2011 Tried hard to provoke bouncing on my 15C LE but fortunately to no avail.
Re: HP-15LE: Anybody else see double key registrations? - Paulo MO - 11-12-2011 It can not be a software debouncing problem. It must be HW related. None of my two LE's does multiple key registers. The sofware debouncing algorithm seems to be doing the job. Ergo...

Which isn't to say that perhaps it couldn't be FIXED in software. It might be a case of some keys / keyboards needing a touch longer debounce than nominal and I've got one that's on the outer edge.
