Since upgrading to 10.8.3 my key board backlight does not come on until I enter my password

(13" MBP mid 2010).  Since upgrading to 10.8.3 my keyboard backlight does not come on until after I enter my password and mac system comes up.  Before upgrade the keyboard backlight would come on right after I pushed the On button.  It makes it difficult to enter my password in a low light setting because I can not see the keys to type my password in.  I have been using the light off of the display to help light the keyboard to see to enter my password.  Any know fix for this?

Hey Doug,
Thanks for your post, and welcome to the Apple Support Communities.
I understand that your keyboard backlight is not working upon startup, the following may resolve your issue:

After performing normal troubleshooting, these symptoms may indicate that an SMC reset may be necessary:

The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature).
You may also want to reset your computer's PRAM:

Note: Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.

    I have iphone 5 and the latest iO7.1. Since upgrading to IOS7.1 birthdays added to a contact are not shown in calendar anymore. It use to show automatically before. Can anyone help?

    Click on calendars at the bottom of the screen. Make sure that birthdays are checked.
    We may think we have 1 calendar, but iPhone puts things in different calendars. Sometimes we can somehow lose one. Well not really lost, but somehow it just gets de-selected. So just make sure that all that you want to see are checked.
    One cool thing I like about this is that they have added US Holidays which didn't used to be there like on most paper calendars. Nice to have them available now!

    In most scenarios you shouldn't need to forward ports, however if you need to, you may be best contacting your ISP.
    As with most router issues, I would recommend that you contact your ISP with details of your problem (assuming that it was your ISP that provided it to you).
    There are simply too many manufacturers with different software features and settings and often different names for such features and settings, that the best advice will likely come from those that are knowledgeable about your particular router.
    Make sure your router/computer allows access over the following ports

  • Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work.

    I have had the same problem but on another forum it was suggested that disabling internet sharing would solve this. This fix seems to work on my machine - why it works I do not understand

  • Short key for copy does not work all the time now.

    There is a world of information in these forums if you use the search function near the top right of this page. Just type in NAS for example and you get many threads on the subject (marked with a green checkmark if it solved the question) another example would be Airport Exterme and sound system. Once you formulate your ideas better then specific questions can be addressed one at a time. You may find that a less expensive choice for a server might be a mac mini. Good luck with your project, ask more specific questions and update you systems profile.

  • Upgraded to iTunes 8.1.1 and now iTunes does not recognize iPod

    I recently upgraded to iTunes 8.1.1 and now iTunes does not recognize iPod. The iPod says "Do Not Disconnect" but the device is not listed in iTunes so it will not sync.

    Hey, we are having exactly the same problem! My old ipod died a slow death so I bought a new nano 16gb 4th gen and I can't use it as itunes isn't recognising any ipod being plugged into it. I've been through the whole support database and every USB port is working on the laptop, so I know the computer is recognising its there its just itunes itself - even removed and downloaded it again but no change! If anybody has any ideas what is going on please let me know!!!!

  • I have a disk in my mac and came not get it out?  I use the command E key to eject but it does note come out?

    I have a disk in my mac but it does note come out useing command e to eject? how do i get it out or do I have to get it jixed?

    Force eject a stuck cd/dvd
    First try the normal methods to remove the disc. Drag its icon to the Trash can in the Dock or select 'Eject' from the File menu.
    If you are running a virtual machine, e.g. VMFusion, ensure that the CD is disconnected from the virtual machine. This will sometimes allow the CD to now show up in Mac OS X.
    Shut down the computer and start up whilst holding down the mouse button. This may take some time, but keep your finger on the mouse button right up until the disc comes out or the log-in screen has appeared.
    If you have Toast Titanium installed on your computer, choose EJECT DISC from the menubar.
    Sometimes you can successfully use the eject disc button in iTunes even if the disc is not visible to the Finder
    Open Disc utility and choose the disc you wish to eject in the left-hand pane, then click on the Eject button.
    Some Macintoshes have a paperclip hole that you can insert a straightened paperclip into, manually triggering the eject mechanism.
    Open Terminal and type "drutil tray eject" to eject the disc/tray, and "drutil tray close" to close the tray.
    If your computer has an eject button on the keyboard, restart the computer holding down the Option key. When the startup disk selection screen appears, let go of the option key and press the keyboard's eject button.

    User,
    I assume that this is for read-only activity. If so, don't create an EO from the database view; create a read-only view object instead. The only reason you'd want to use an Entity Object is if you were going to insert/update through the EO; unless you have an instead-of trigger, this database view is non-insertable/non-updatable.
    Short answer: I think what you want to do is a read-only View Object (not EO) - put "select x, y, z (your columns) from view_name" as the SQL.

  • FN key menue bar does not appear on Satellite R

    PROB-1: i bought this Lap before 4 months.. suddenly my FN key is not working... that is, if i press FN key, menu bar does not POP OUT, but if i hold FN key and press F7 or F6, the screen brightness is changing.
    I got this in Saudi Arabia, the key board also have Arabic font (which i really dont want).
    PROB-2: If i want to type "@", i have to press ' Shift+" ' instead of ' Shift+2 '
    pls help on these..

    Hi
    Prob 1:
    The FN button row which appears at the top of the display is controller by Flash Card Support Utility.
    Go to All Programs -> Toshiba -> Flash Cards and restart this software.
    If this does not help, then reinstall this tool.
    Prob2:
    I assume you keyboard language setting does not match with the keyboard layout.
    Simply change the keyboard language setting.
    I assume you will need to change this to English (United state)

  • I have paid for the Mountain Lion. But for some reason, I cannot seem to download it, despite software being upgraded. Anyone facing this problem where the download does not begin? How can I solve this?

    I have paid for the Mountain Lion. But for some reason, I cannot seem to download it, despite software being upgraded. Anyone facing this problem where the download does not begin? How can I solve this?

    Make sure your Mac qualifies to run Mountain Lion >  Apple - Upgrade your Mac to OS X Mountain Lion.
    Try disabling anti virus software and turn off the Firewall in System Preferencs > Security & Privacy
    Apps such as Little Snitch and Net Nanny can prevent apps from downloading from the App store including Mountain Lion.
    Third party download managers are not compatible with the App Store.
    Keep in mind, for downloading Mountain Lion from the App Store, a high speed (broadband) internet connection is strongly recommended by Apple as noted here > iTUNES STORE - MAC APP STORE - TERMS AND CONDITIONS
    If you need to reinstall OS X or repair the the startup disk using Mountain Lion Recovery, that requires broadband access to the internet via Wi-Fi or an Ethernet connection. OS X is downloaded over the internet form Apple when OS X Recovery is used for reinstallation.
