I wouldn't be here typing this if I hadn't tried everything else I came across on the internet.

 

My story goes like this: at some point today, my keyboard became incapable of giving me a capital s when typed with either shift key, but it's perfectly capable of typing the letter s in lowercase. I can do the caps-lock s if I want it capitalized, but I'm already conditioned to doing single capital letters with the shift key, so I really don't want to convert my entire way of typing. It doesn't even seem to matter what application I use, if I have the ability to type, I can't type shift+s for the capital s.

 

Based on various articles found online, I've been through checking keyboard shortcuts, even restoring them to the detaults (because by default, there shouldn't be a shift+s shortcut for anything, obviously), and even checking, double-checking, and changing the text-to-speech shortcut (which is also turned off, as I don't need it in use).

 

The first thing I tried doing was to restart the computer. As laughable as that is, I've been around computers long enough to know it's actually a valid way to resolve minor issues. No luck. I even repaired permissions, and verified and repaired the hard disk (of which, there was nothing to repair at all) by using the disk utility on the snow leopard (10.6) disc.

 

The most recent addition to my computer has been a wireless mouse, a Logitech m510, which I bought about a week or two ago, but things were still working fine on the computer after adding it. I added the Logitech Control Center software for grins and giggles that same day, which really didn't change anything. As for the keyboard, a Logitech G110, I've had this for at least a year and have been using it without issue.

 

Any suggestions would be greatly appreciated. I'm sure I'm not the only person who has had the shift+s issue and not have it related to text-to-speech.

 

Thanks in advance!

    Test it when you boot in Safe Mode.

  • LunaDragon Level 1 Level 1 (0 points)

    I see the login window when I try to do a safe boot, but it doesn't say "safe boot." I have it set to log me in automatically, so it's only doing part of the safe boot procedure.

     

    Right now, as a matter of fact, I'd be in safe boot if all seemed to go well, and I can't do shift+s for the capital s.

     

    Does it mean anything for the computer to do a string of @^@^@^ during startup while it's waiting for something to be accessed/loaded/checked/etc?

  • LunaDragon Level 1 Level 1 (0 points)

    I opened the Keyboard Viewer, and figured this much out:

     

    If I hold down the shift key, it capitalizes all of the letters, etc. as it's supposed to. If I hold down shift and press s, it acts the same as if I press down one shift key and, while still holding it down, press the other shift key, in that all the letters are then in lowercase. The s key isn't acting like another shift key, in that if I press the letter s to have it in lowercase, it's apparent that I can type the letter s.

     

    Does this get anyone any closer to a possible solution?

    In addition to Text to Speech, did you also double-check Speech Recognition?

     

    Have you added any kind of 3rd party software to your machine which is designed to do things with text?

    Follow the procedure indicated here

    In speech recognition, speakable items is turned off, and the key to hold down is, by default, the Esc key.

     

    The only other third-party software I've used would be Amazon's MP3 downloader. Otherwise, I had Pages (Apple word processor) opened, and right now it's not running.

     

    On a regular basis, I'm running Firefox, safari, Adium and iTunes, plus the G-series Key Profiler which just allows my keyboard to display in pretty colors and detect macros assigned to the G-keys (like F-keys, but off to the left side instead of being above the numbers). Firefox didn't run any updates, and as for Apple software, nothing changed after I did run my updates last night.

     

    I had a friend on Facebook suggest that I take the keyboard to the Apple store, because it might just need to be cleaned. I don't think that's the case, based on what happens when I press certain keys. But also, I don't think they'll touch my Logitech keyboard.

     

    What's the next suggestion? I'm about two seconds away from trying a keyboard off a Windows computer, but I'm really hoping the keyboard itself isn't the issue.

  • LunaDragon Level 1 Level 1 (0 points)

    If you know how I can remotely log into my Mac from a Windows computer or from my iPhone, I'll try a safe boot that way.

     

    As I said, the login screen does not say "safe boot" once I get to it, even though it does come up when I normally log in automatically. Right now, for example, I should be in safe boot but I'm not.

  • LunaDragon Level 1 Level 1 (0 points)

    This strikes me as odd, but... why would this issue have persisted?

     

    I just absconded with a keyboard from an HP computer, and I'm able to shift+S. I really don't understand why the s-key, when lowercase, works, but when the shift key is pressed, that is the only letter which does not work.

     

    So as it turns out, I'll be purchasing a new keyboard for my computer. On the upside, I know the rest of my computer seems to be in working condition.

     

    Thanks to both of you for helping me troubleshoot this. Again, it's not the resolution I wanted or expected, but at least it's resolved.

    To connect remotely, Remote Login must be enabled, and firewalls configured accordingly. At any rate, I do not believe it is possible to Safe Boot remotely.

    Make sure to disconnect all peripherals prior to safe booting. Then, if you have followed the procedure correctly, but still are not in Safe Mode, you may have a hardware issue.

     

    Reset the SMC

     

    <http://support.apple.com/kb/HT3964>

     

    and, for good measure, the NVRAM

     

    <http://support.apple.com/kb/HT1379>

     

    and try again to Safe boot. If it still doesn't work, then the keyboard is defective. Try an external Apple keyboard to be sure, but don't hope for too much.

    G-series Key Profiler which just allows my keyboard

    If you have a problem with the keyboard, then your first troubleshooting step should be to remove any third party tool (and I do mean any) that could interfere in any way with it or modify its response. Key Profiler is a prime candidate. That's why my first advice was to boot in Safe Mode, which should prevent such software to load. However, Key Profiler should not be able to interfere with Safe boot.

  • LunaDragon Level 1 Level 1 (0 points)

    The article about starting in safe boot goes on to mention how to do so if the keyboard doesn't work, and it says about needing to access the computer remotely. I'm in a one-Mac household,

     

    I had the G-series Key Profiler app running the entire time I had a different keyboard attached just now - that app wasn't the issue. It seems obvious to me that the issue is with the keyboard itself, though it baffles me because it acts software-broken, not peripheral-broken.

    You don't need to access the Mac remotely, because you can still enter commands from the keyboard. But first, do the SMC and NVRAM reset.

     

    Then, for the Safe boot, launch Terminal, enter the command mentioned in that article

     

    sudo nvram boot-args="-x"

     

    press Return and restart.

     

    The problem is that the Shift key at restart works at a low level, so it shouldn't be intercepted by any third party tools, which load later. If it doesn't work, then a hardware fault is the likeliest explanation.

  • fane_j Level 4 Level 4 (3,660 points)

    Two more points.

     

    (1) Remember that you need to revert the NVRAM setting to boot normally

     

    sudo nvram boot-args=""

     

    (2) If, even in Safe Mode, the Shift key still doesn't work as expected (which is my bet), revert to normal booting, then try to boot in Safe mode by using the other Shift key. Although they are almost always treated as if they were the same, they are actually independent and have different key codes.

    I have this problem on an iMac, (Mac OS X (10.7.3), 2.16 GHZ Intel Core 2 Duo), using the keyboard that came with the Mac.  But my problem is with the upper case "z".  Keep me posted!

    Have you double-checked system prefs/speech that this letter has not been set as the trigger for TexttoSpeech or SpeechRecognition?
