Resetting Keyboard and Screen Lights

Is there a way to revert settings for changing brightness of keyboard and display to the default? I was changing the brightness for the keyboard and screen, and now I want it back to how it was because I don't think it is adjusting correctly now.

You can try deleting the preferences file called something like:
com apple bezel services.
You may find one in your home directory>library folder>preferences
Plus there may be one in:
macintosh HD>library>preferences
Delete both and re-boot. It may or may not cure your problem. It did it for me when mine went hay-wire.

  • HT2693 keyboard and screen protector affects display on retina macbook?

    i have read the issue about the palm guard affecting the display here: http://support.apple.com/kb/TS4384
    I am just wondering if using keyboard and screen protector will have the same effect if i put it on and close the shell cover?

    If you want to try a hardware test, try holding down option-D (works for me for some reason). However...
    If a SMC reset doesn't fix anything, then I would take the machine into your local Apple Store or AASP. You shouldn't be having such problems with a new machine.
    Try the SMC reset first - I doubt that it will fix anything.

    Try an SMC Reset. (System Management Controller)
    Shutdown>unplug from power for ten minutes>press and hold in the power button for ten seconds>startup again.
    Also try a PRAM Reset. (Parameter RAM)
    Shutdown. At the bootup chime, hold down CMD-Option-P-R together, wait for two more chimes, total three, then let go of all keys to finish booting,
    If this doesn't do it, run the Hardware Test in Extended

  • Can I use a 15" MBP as keyboard and screen to work on bootable drive MBP 17

    Hi, all,
    I already asked this question in a post with other questions more prominant so I am trying this as a solo question. I have a MBP 17" intel Core Duo that will be going in for repairs. I have an OWC 1 TB drive formated to be bootable. Can I boot from the external HD from a 15" MBP Core Duo and use it essentially as a keyboard and screen and work on the 17" files with all the software or can I only transfer files to the 15"? The 17" has Leopard and Adobe CS3 (which I cannot do without) the 15" runs Tiger and I run CS2 on it.
    Thanks!

  • Foam sheet between keyboard and screen, Replacement?

    Hi,
    I'm wondering if anybody knows if this has a part number ? and where can
    I get one ?
    I'm wanting to know if I can get a factory replacement of the thin foam sheet
    that is part of the packing materials that goes between the keyboard and screen.
    You know, when your Powerbook was new, when you opened the lid
    for the first time, there was that thin foam sheet over the keyboard, speakers,
    trackpad the whole surface area. I guess it's more like the foam is the size of
    the whole screen area, to protect the screen.
    This may seem silly to want to replace this, but I have a PowerBook that's coming
    up on 3 years old and every time I have closed the lid (screen) I have put the thin
    foam in to protect the screen. So, the screen is perfect after 3 years.
    Much different than my co-workers PowerBooks. They didn't see any
    need for this foam and didn't use it and their screens are etched / scratched from
    the keys, mirror images of the keys scratched into their screens.

    Hi there,
    I'm not sure if Apple assigns part numbers for their packing materials, but you could either visit your local Apple store to see if they happen to have any of these lying around, or you could purchase a screen protector to do the job.
    I used the foam sheet for a few years, but lost it recently, so I went out and bought an iKlear Cleaning kit which included a polish cloth which is the size of the keyboard and trackpad area, and I find it does a fine job of protecting the screen.
    Go to klearscreen.com and have a look.

  • Keyboard and Trackball Light not Working

    I recently received a BlackBerry 8830 from a friend and the keyboard and trackball light aren't working. He's a stand up guy so I know he wouldn't sell me a faulty phone.
    The Backlight Brightness is 100.
    Is there a setting that needs to be changed or something that I need to download?
    Is it possible that the light is faulty and needs to be changed?

    Try re-setting the device by reomoving the battery for 30 seconds and then replacing. 
    That would be the first step.

  • HP Officejet 6310xi won't print - keeps blinking "reset power" and all lights flashing.

    I have an HP Officejet 6310xi that won't print.  When you select print, the paper begins to feed then suddenly stops before any printing begins and all lights on the face of the printer begin blinking and the message "RESET POWER" blinks in the screen readout of the printer.  When I turn printer off and back on, the screen indicates a used color cartridge is inserted and I hit OK, then indicates used black cartridge is inserted, then I hit OK, then it says it needs to align cartridges, I hit OK.  After trying to align cartridges, it suddenly stops and goes back to all lights flashing and screen flashing "RESET POWER".   I can hit cancel during cartridge alignment and printer goes to normal ready position.  I can then print a test page.  But as soon as I try to print anything else, even the diagnostics page, it goes back to flashing all lights and "RESET POWER".  I did a semi reset (unplug, wait, plug in holding #6) and a full reset (with #9).  That did nothing except wipe out the date on the screen read out of the printer.   So I know the full reset executed correctly but it did not solve my problem.  Please HELP! I am reposting with email me selected - I'm new at this posting to forums...

  • Light on keyboard and screen DIMMING ON AND OFF

    Why does the lights come on and off when I'm typing it P**s me off. I realize my hand must be covering the sensor but how is it situated on the keyboard

    Hi Fats1973: Yes, the light control is a bit of a pain isn't it? I have downloaded and use "LabTick". It is great little control program to set the light level of your backlighting. It can be found at: http://labtick.proculo.de/

  • Keyboard and screen scrolling freezing up after software update approx. 30 days ago.

    2 year old 16GB IPad (Model MD522LL/A) Recently (last 30 days) installed recommended software update (sorry do not recall number of update). Now having problem with keyboard freezing when messaging as well as screen freezing when scrolling. Can sometimes be temporarily resolved by rebooting (turning off, waiting 3 to 5 minutes and restarting).
    Thanks for your assistance.

    Thanks for that, I did go looking for it but couldn't find it.
    Unfortunately, resetting the PRAM and NVRAM didn't work. Will a reinstallation of OS X make a difference, bearing in mind I've already restored from a Time Machine backup? (I don't know if those clone everything or don't include system files).

  • Protecting MacBook Keyboard and Screen

    Can anyone recommend a decent screen and keyboard protector? I have a toddler that it is difficult to keep her away from the laptop. Closing the lid is not always convenient.
    Just something that would protect the keyboard from accidental water spills (but thin enough to type on) and something for the screen that is almost crystal clear while protecting from fingers prints/crayon marks. BTW - The screen is the anti-glare version.
    Thanks.

    Previous poster had it right. You really need to find a way to keep the laptop away from the toddler, rather than trying to use minimal protection on it (which keyboard protectors are, at best).
    I have two cats at home which have the potential to be destructive. Fortunately they are older and less active now, but for those times when I am home but not near the computer, I bought a laptop stand which is difficult for them to tip over, and is rollable so I can roll it away from other objects which make it easy for them to jump or climb from. I do close the lid on the laptop so that if they do manage to find a way onto the stand, they can't tip the laptop off the stand by knocking into the screen or damage the screen or keyboard with their claws. And I have a strict, strict, strict policy of no liquids within 10 feet of the computer (this by experience, I have dumped an entire mug of coffee on a $70 wireless keyboard.... expensive lesson but not nearly so as if it had been my $2600 MBP... hint taken)
    If you can't do something similar to this, simply find a room to use your laptop in where you can securely shut the door when you leave.
    I use a Moshi keyboard protector which is good enough to keep away the random water drop or two (and I mean drop, not a whole glass of water). There isn't a keyboard protector that will prevent a large scale spill and at the cost of repairing liquid damage to your MBP, the best protection is prevention.

  • Cleaning Keyboard and Screen

    What do you guys use and what's the best method?
    So far I've just been using a soft shaving brush
    to clean the dust off. Smudges and fingerprints
    are another story.
    Thanks.

    Like the others I use a micro fiber cloth but with the tiniest squirt of glasses (as in spectacles) cleaning spray which works a treat on the palm rest area of my white MacBook. Try a tiny area first though to check it doesn't damage the finish. I forked out about £15 for a specialist cleaning spray last year from an Apple store but it's just not worth the money.

  • Mbp keyboard nonresponsive, screen freezes, ideas?

    My MBP keyboard and screen freezes; any ideas on a fix?

    Reset the SMC (may take 2-3 attempts) and also do a PRAM reset. Instructions are in Intel iMac SMC and PRAM resets. If that does not fix the problem then please post an EtreCheck report of your computer in your reply.

  • Mac air keyboard doesn't light up for login

    After Yosemite install, the keyboard on my Mac Air does not light up until after I login.

    Pushkin,
    I found that if I turn on FileVault my keyboard backlight doesn't come on at initial Login screen from boot. Nor can I adjust the brightness of my screen or keyboard backlit. The moment I turn off FileVault I can then adjust those things and everything works fine.
    I say initial because if I log out of my user and am taken to the login screen I can adjust both keyboard and screen backlights.
    You can see if you have FileVault turned on by going to System Preferences -> Security & Privacy -> FileVault (Tab)
    Also I think that its important that we let Apple know this is going on. If you feel up to it I would send them feedback. I mean if you would like to that is. https://www.apple.com/feedback/macosx.html
    Hope that helps,
