I have the same problem.
Kestrokes seems to be ignored randomly!
I would like to take this oppurtinity to point out that THIS IS DIFFERENT FROM the ELP-problem that everyone keeps refering to!!! (I have that problem too, this is different!!)
I have found the following methods to be effective in reproducing this bug:
(..could come in handy in case you need to prove the bug (or flaw) exists to some one
cough*apple*store*people*cough..)
Method 1:
Try pressing down two keys at once by pressing right between them. Try different combinations and different levels of pressure! For instance, when I press right between my J- and K-key nothing happends! If I keep my finger at certain angles or press hard I can usually get a K, sometimes even a J.
(For reference: on my PowerBook I
always get both a J and a K regardless of angles and pressure - as long as the keys a pressed down the produce letters.)
Method 2:
This one is similar; Try pressing on the corners of keys with the very tip of your finger. For instance, on my keyboard almost
all sqaure keys are unresponsive when pressed with on the corners of them.
(For reference: My PowerBook does not have this problem.)
Method 3:
Take a finger and rather quickly but firmly drag it across your keyboard top row (from Q to P). When I do that I get:
QWP
(I held down Shift or clarity.)
Results vary - but some letters are always missing!
(For reference: on my PowerBook I
always get QWERTYUIOP no matter how quickly I do that!)
Maybe we could simply call this problem the QWP-problem - so that we can differ it from the ELP-problem?
I think this is clearly a hardware problem - in my opinion, those keyboards are flawed 😟
I hope Apple agrees with me. Hm, have anyone tried to get a new one yet?
Best Regards
