HP 35S teardown with video Message #1 Posted by Tom Mathes on 6 Mar 2008, 9:14 a.m. Article with accompanying video of a teardown of the 35S: http://www.techonline.com/product/underthehood/206800966 What surprises me is in the video they discuss testing of the calcs, how HP tests every calc in every lot. If they do all of that then how come so many of us have had bum keyboards? Something surely is amiss here.

Re: HP 35S teardown with video Message #3 Posted by Tom Mathes on 6 Mar 2008, 10:39 a.m., in response to message #2 by bill platt Maybe the problem is overstated here but I don't think I've read about as many people having keyboard problems with the other HP calcs built recently. Or am I mistaken? I can say I've had two in a row now with keyboards not as well engineered as HP claims.

Re: HP 35S teardown with video Message #4 Posted by bill platt on 6 Mar 2008, 4:02 p.m., in response to message #3 by Tom Mathes The 49G+ had a bona fide problem that was heavily represented--far more than the 35s or the 33s reports. Even the 17bii+ and 10bII had more keyboard grousing than for the 35s.

Re: HP 35S teardown with video Message #5 Posted by Tom Mathes on 6 Mar 2008, 5:00 p.m., in response to message #4 by bill platt Then I stand corrected. I'm one of the unlucky ones who got a bum unit out of the box. I hope this replacement doesn't have the same issues.

It's just a fact that dedicated people on forums like this like to have a whinge when something goes wrong. So the duds get amplified and you won't hear from the vast majority who have had no trouble. I greatly doubt HP tests every calculator for key actuation force, so it's inevitable that you'll get a small percentage of less than optimum tactile domes from the manufacturer. Dave.

Re: HP 35S teardown with video Message #7 Posted by Walter B on 6 Mar 2008, 5:37 p.m., in response to message #1 by Tom Mathes IIRC, I've read the same article before already. Maybe some months ago, it was discussed here in this forum. Particularily remember the "LCD diver" ;)

Re: HP 35S teardown with video Message #8 Posted by Hans-Erik Lehndal on 7 Mar 2008, 10:03 a.m., in response to message #7 by Walter B I must be living in a galaxy far away, but my now rather old HP49g+ works like a charm, while my brand new HP35s didn’t register more then 50-75% of the times when I pressed “7”. HP did not(!) respond to my email. Shame on them! I gave the little rascal some rough treatment including a moderate amount of violence, and now it seems to work. I guess all those 25 screws that hold the keyboard together could be handled without opening the calculator after all :)

Re: HP 35S teardown with video Message #9 Posted by Tom Mathes on 7 Mar 2008, 11:23 a.m., in response to message #8 by Hans-Erik Lehndal I've found with the calculators it's best to call them and not use e-mail. I sent 5 e-mails before I got not an e-mail reply but a phone call to the e-mail. Try calling HP instead. It sure was more effective for me.
