Wired keyboard on a Powermac G5 not behaving.  Functions keys are all that work, letters not resonding at all.  Mouse works though (it connects through the keyboard).   Any suggestions or ideas?

PowerMac, Mac OS X (10.6.8)

    Not sure this'll work, but...


    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...

    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive

    Reboot, test again.

    Check in System Preferences > Universal Access > Keyboard, and make sure that neither Sticky Keys nor Slow Keys has been enabled.


    Also, in System Preferences > Universal Access > Mouse, make sure that Mouse Keys has not been engaged.


    One other possibility, perhaps. Since you have a wired keyboard, it probably has a built-in keypad. Make sure that NumLock has not been turned on - it can cause odd keyboard responses. To turn it on/off, hold down Shift and press the Clear key in the keypad (that's the key immediately above the 7 key).

    Were you ever able to fix this? I'm having the same issue with my laptop and I can't type the letters are not responding and seem to be shortcuts only.

    Can you type normally if you physically take out the battery, let the laptop rest without the battery for a little while and then power up with only the adapter and cable, without the battery?


    If so, you may have a swelling, bulging Apple battery that is exerting upward pressure n the trackpad.


    Very common with certain kinds of Apple laptop batteries.


    Replace it with a generic battery from—not with the overpriced (and prone to bulging) Apple battery.
