The Keyboard of the 48GX is unbeatable. The 49G is horrible (feeling only, it has 12+ years and still working). The 50g keyboard is as close as you're going to get to the 48GX keyboard in a new calculator. Best wishes

What I found was rather surprising. The "/" key dome was NOT collapsed. It feels and clicks just like all the other domes when I press it with my fingers. Under each key is a tiny plastic post. When you press a key, the post pushes against the dome which makes the tactile click and contact. The problem with my calculator is that the post on the "/" key is significantly shorter than the other keys -- so short that I have to push really hard to make contact. It worked fine for three years, so I can only surmise that the post got worn down. (I have pics if anybody wants to see.) It's hard for me to imagine that I wore it down with my usage. I'm a high school teacher and use the calculator regularly, but I don't use it all day and I don't really hammer on it. (No adrenaline rush when I do division.) It seems like other more frequently used keys would have worn down before the "/" key. Someone mentioned that HP switched to a more flexible plastic to prevent keys from breaking. Perhaps this is the culprit: more flexible -> softer -> wears down faster. My son also has a 50g. His "/" still clicks, but it does feel a little different than the other keys. Is there a design flaw in the length of the tiny post on this key? If anybody has a dismantled 50g laying around, take a look under the "/" key and let me know if the post is shorter than the others. Does anybody have any ideas how I can fix this? I was thinking of putting a drop of some really hard-drying glue to buildup the length of the post again. Any suggestions? -wes |
