Does setting the screen brightness to the MAX shorten the life of the LCD?

On daytime I set it to about 80%. That's bright enough.
Also, another thing I noticed was I tried to cover the speakers with my hands. The keyboard lit up a little bit but the screen dimmed down. Is it normal?

While setting the brightness to maximum doesn't shorten the LCD's actual lifespan it does however, I believe, speed up the degradation on how bright your screen will be.
As for when you cover the speakers… yes, this is normal. What's happening is that the ambient light sensors (which are under the grilles, are picking up a reduction is ambient light and in doing so is setting the screen brightness down and activating the backlit keyboard.

  • NB100 - How set the screen brightness?

    Hi all.
    Just bought an NB100 - overall very very pleased with it. Well built, good screen and very compact etc.
    Got a couple of questions? The screen brightness is controlled by Fn+F9/F10. I like to have it set to "halfway" or less - partly to preserve battery - but also because I find max brightness is actually TOO bright for me! But on reboot the machine seems to always start at maximum again. Is there any way round this? Does it perhaps need a firmware update (my machine seems to be running version 1.90 which I believe is the latest)?
    I noticed other threads mentioning Fn + F8 as a means of selecting Bluetooth/Wlan etc? Mine seems to just control the fan setting and processor speed - The "grey" fan setting gives 1.6ghz and the fan comes on - whereas Fn+F8 toggles a "white" fan icon - where the processor throttles down to 800/900 ish and the fan slows/stops(?). [in passing I've noticed some videos become "jerky" if the lower setting is chosen]
    I'm not 100% sure what Fn+ "pipe" key does (to the left of F1)? The Fn+F1 switches on wireless/wifi I know - but the "pipe" key seems to be a Wlan symbol (or is that the key to use for Bluetooth or GPS or whatever)? Sorry to sound so ignorant - but the user guide doesnt go into that much detail. I'm fairly sure the machine I bought - which was a Toshiba Refurbished/Reconditioned NB100 - model PLL10E - hasnt got any BT/GPS etc - just the basic wifi which F1 switches on and off.
    Final comment - and others have said this - the key tops are very difficult to see in low light!! The "grey" colour was definitely a design mistake! But I can live with it - either a usb light? or some stickon (white) letters?
    Regards to all.

    hi, i think the best way to set brightness is in options of energy properties accessible in system tray icon. I know about bt and wlan activation, it seem that bt and wlan dispositives are on the same circuit on/off, so not indipendents. Nb100 is a good inexspansive machine :)

    How to change the screen brightness on a macbook?
    My Macbook is a May 2010 model in white
    I am looking how to change the brightness using the keyboard, because I know how to change it using System Pres

    The F1 and F2 keys control brightness.  Depending on how you have your function keys set up, you may have to also hold down the fn key to activate.

  • My 2009 iMac is making a very loud,rapid pulsating electronic noise. It stops temporarily after adjusting the screen brightness or using certain apps. But it always returns

    My 2009 iMac is making a very loud noise. It sounds like a rapid, pulsating electronic noise. It stops when the screen brightness is adjusted or when using certain apps. But it always returns and is getting louder. The unit was shut down for 4 months and the house temperature was set to 5C. It was powered up 2 weeks ago and ran fine for a while. Then in the last 5 or 6 days the problem started. 5 days ago I did watch a bike race for 3 or 4 hours from a quasi legal stream. I am not tech savvy. Just very confused as I've had a trouble free run so far. Ditto with my iphone5.

    I would recommend taking it in immediately to your local Apple Store or AASP to be loooked at by an Apple Genius. I suspect you made a goof somewhere but diagnosing noises without seeing it is really difficult.

    Hi, raneth's boyfriend!
    Unfortunately, iTunes was told to restore all data from an old backup onto the new phone, and that cannot be undone.
    However, prior to this, iTunes 10 would have also asked to make a backup of the phone before doing the restore.  If the user elects to say "yes" to perform the backup, then iTunes would have backed up the phone before erasing it.
    Hopefully, that backup will still be available in iTunes, and if so, it would be backed up under the new phone's name prior to it being erased and restored (if the name of the new phone is different to the name of the old phone).
    To check if iTunes has a backup of the phone prior to the restore, look in the Devices category in iTunes Preferences.  All backups made are timestamped and are identified with the iPhone's name at the time of the backup.  Look for:
    • a backup of the phone using the new phone's name prior to the erase and restore, or
    • a backup with the same date and time as that when the phone was erased and restored (not the date and time AFTER when the phone was erased and restored!).  This may be the case if the new and old phones have the same name.
    If a backup is available, you can erase and restore again using that backup. The phone will be restored with what would hopefully be the original image of the new phone.
    If no backup was made prior to erasing and restoring the phone initially, then there is no way to
    undo it, meaning your phone's original data has been lost.

    Connect the iOS device to your computer and try to make a backup (if you want)

    Then restore via iTunes. The iPod will be erased. Place the iOS device in Recovery Mode if necessary to allow the restore.
    If recovery mode does not work try DFU mode.

  • TS3824 How can we install the iMac Graphics Firmware Update if the screen is white and I can't get to the Apple menu?

    How can I install the iMac Graphics Firmware Update 2.0, if the screen is white and I can't get to the Apple menu?  My computer has 5 vertical purple lines against white screen at startup before the Apple logo appears and the spinning gear...then everything disappears and the screen hangs on the white screen.  I have tried unplugging and removing all my peripherals and the COMMAND, OPTION, P & R set of keys and still nothing.  I have tried COMMAND C to start up from cd and it only tells me to turn off the computer and turn it back on.  I found information on Apple's Support pages regarding the iMac Graphics Firmware Update but I am unable to download and install if I can't get to the Apple menu.  Can anyone help?

    You may have hardware problem, I think a visit to your local Apple Store or AASP is in order.

  • Screen Saver when calling and need to use the Keypad, the screen saver doesn't detect the phone has left the ear and blanks out the screen.  Even ending a call is difficult as the screen blanks out within seconds

    I have to use the Keypad a lot when making calls.  Make the call, the Robot then asks to enter a number for a service, pull the phone down from the ear, the screen may light up for a second, but then the screen saver cuts in, blanking the screen out.  Sometimes you hit the Home Key to awaken the sccreen, enter your number and then back to the ear to hear the next set of instructions.  Back and forth just trying to enter the options is a pain.  Sometimes even trying to end the call, the screen blanks out and you fight to try and end a call.
    If I use the Speaker function the keypad works; the speakler phone is not alway appropriate. 
    It appears that the phone gyro, doesn't detect the phone has moved from the ear to the viewing angle.  This wasn't an issue until recently and I can't remeber if it's the iPhone 5 or one of the updates.  It definitly wasn't there earlier on, as I threw away an Windows 6.5 phone for the same problem. 
    I'm not sure if it's a hardware or software (design) issue.

    It is not the gyro. This has everything to do with the iPhone's prioximity sensor.
    Are you using a case that may be blocking or partially blocking the proximity sensor? If you are using the case, remove the case prior to the next call to see if the same occurs without the case.

    (1) Is there any way that I can get the transition menu to remain on the screen. I select a transition, drag it to the timeline and after I click done I have to start the process all over to perform this action on the next transition. I have premiere elements 12. In older version the menu would stay on the screen.
    (2) In pan and zoom how can start zoom on a photo in the original picture and zoom in and the next picture zoom out and the next photo pan from right to left and the next photo pan left to right.

    What computer operating system is your Premiere Elements 12 running on? If you have not already, be sure to update 12 to 12.1, using an opened project's Help Menu/Update.
    But to the immediate questions, assuming Windows 7, 8, or 8.1 64 bit....
    1. No, it is what it is. But, are you applying the same transition each time? If so, then highlight/select all the clips involved (all at one time), then Timeline Menu/Apply Default Transition will do just that for the highlighted/selected clips.
    To highlight/select more than one clip at a time, hold down the Shift key of the computer main keyboard and then click on each clip that you want in the group selection
    or
    with your mouse cursor draw a rectangle around the clips that you want to select
    2. Are you using the Premiere Elements 12/12.1 Expert workspace Pan and Zoom Tool? Or the pan or zoom presets under fx Effects/Presets/? With those you can do pan or zoom, not pan and zoom.
    Or, are you in the Elements Organizer 12 Slideshow Editor using the pan and zoom effect there? Or, are you using keyframing the Motion Scale property for zoom and the Motion Position property for pan?
    Are you asking about photos with landscape or portrait orientation?
    The pan and zoom tool does one photo at a time.
    Have you read the Adobe documentation on the Pan and Zoom Tool?
    http://help.adobe.com/en_US/premiereelements/using/WSeffff8bffc802084-494411db12fd35452dd- 8000.html

  • TS3274 My App Store shows 3 updates but when I go to it the screen is blank. It will not give me the option to update all or one at a time, it doesn't show the apps at all.

    My App Store shows 3 updates but when I go to it the screen is blank. It will not give me the option to update all or one at a time, it doesn't show the apps at all.

    Many people are having this problem for the last couple of days. This is a problem that Apple has to fix. If you look around the forum, you will see many, many discusssions about this and they have been going on for a few days.
    According to Fly150 in another discussion, this is a workaround - for the time being.
    If you want to update the Apps while waiting for Apple to fix Updates:
    1. Go to App Store
    2. Select Purchased
    3. Select All
    4. Scroll down to find the Apps showing update
    5. Select update on the Apps
    This should update the Apps and get rid of the update count in App Store.

  • I can no longer see my pictures.....the screen is white boxes but when I click on the box an exclamation point pops up. Please Help!!!!

    I can no longer see my pictures.....the screen is white boxes but when I click on the box an exclamation point pops up. Please Help!!!!

    The exclamation point occurs when iPhoto breaks/loses the file path to the original file.  So try the following: make a temporary, duplicate copy of the library and apply the two fixes below in order as needed:
    Fix #1
    Launch iPhoto with the Command+Option keys held down and rebuild the library.
    Select the options identified in the screenshot AND
    the option to rebuild the small thumbnails. 
    Fix #2
    Using iPhoto Library Manager  to Rebuild Your iPhoto Library
    Download iPhoto Library Manager and launch.
    Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
    Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
    In the next  window name the new library and select the location you want it to be placed.
    Click on the Create button.
    Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
