Encore 2 8-inch: Brightness bug? Turns to the maximum on its own.

There is no brightness percentage on the slider, but for the argument's sake I shall use 0% to 100%.
I) I set the brightness to 5%
2) Sleep the device
3) Wake up the device
4) Randomly the brightness is set to maximum. Yet the slider remains as I set before. So when I move up the slider from 5% to 50%, the brightness actually gets down (because it was really 100%, and now it is chaned to 50%).
Does anyone have this but? I have updated everything including the firmware, disabled Display Power Saving, changed all display brightness values to 5% in Windows power settings, and I have not installed any third-party applications.

same problem as in wt8-a32. no fix ever from toshiba.... dont bother w tech support.  they r useless idiots that will tell u the same bs of reseting upgrade bios etc... if u already got the latest bios and this is not fixed too bad... i upgraded my wt8-a32 to latest bios w countless other people and this problem came up after that.... been over 1 yr and no fix .... so forget any help from toshiba

  • Why does the brightness turn up to max on its own?

    I have an iPhone 5 with ios 7.1
    I dont have auto brightness turned on and keep my brightness around 40% so I dont drain my battery and its as bright as I need it.
    I noticed the brightness turning up to full brightness by itself whether im inside or outside and cant figure out why or how. Its very annoying.
    I also turned it onto auto brightness to see if it would help but it is still doing it up to max by itself. Can anyone help please?

    Exiting FULL screen is triggered by one of three things.
    1. Pressing "ESC" on the keyboard - a "user input".
    2. Clicking the "toggle" on the player interface, which placed the video into FULL screen - again, a "user input".
    3. The page refreshing or new content loading in the page - can be "user input", or something like a javascript or ad in the page.
    Since Chrome uses its own "proprietary" plug-in, which functions independently of the ActiveX (IE) and Standard Plug-in (Firefox), you can uninstall and reinstall all day long and it'll have no effect on Chrome. You can't download or update "PepperFlash" from here.
    If you go to the Chrome Settings:
    Click "Show advanced settings..."
    and click "Reset browser settings"

  • How to avoid turning off the iPhone when its locked.

    Hiya,
    Wondering if there is any settings to avoid turing off the iPhone when its locked. When the phone is locked with passcode holding the power button on the top provides the option to turn off the phone. So is there any way to restrict it?
    Thanks,
    SaN

    No.

  • How can i turn off the rotten restrictions, its so easy to turn on but impossible to turn the stupid thing off

    i have been trying for days to turn restrictions off, but there is no easy way to do it, i dont have the password as i bought it from someone and they say they dont know it, it is stopping me from doing many things.
    I am so frustrated with this I PAD it is not user friendly at all, sorry i bought it now, i found a message to tell me how to do a reset, which tells me to go to the summary button, but cannot find it anywhere, go to help and its no **** help at all, 144 pages of no help in the manual its totally confusing and make for computer geeks not the new users.
    Is there someone out there that is smarter than the fools who set up IPADS in the first place. that can help me reset this dang thing b4 i throw it up the wall

    I don't think that you will necessarily need recovery mode as long as it is only the restrictions Passcode that you need to reset.
    First of all, you should be upset with the person that you sold you an iPad that had a restrictions Passcode that they could not remember. They put you in a bit of a bind. You have to erase the device and start over now, which is what the person that sold you the device should have done before they sold it to you.
    Connect the iPad to any computer running iTunes - ideally your own if you have content that you want to sync. Launch iTunes. Click on the iPad name on the left sidebar under the devices heading. Click on the Summary Tab on the right. Click on the Restore button. This will restore the iPad to factory settings and erase the restrictions Passcode.
    If you are running iTunes 11 - go to View>Show sidebar from the menu at the top of the screen so that you can see the iPad under the devices heading.
    You absolutely must do this on a computer running iTunes or you will never be able to unlock the restrictions.
    This explains how to restore, although I gave you the instructions above.

  • My LED light turns on and off on its own, how can I fix this?

    I dropped my phone today and my LED light on the back by the camera turns on and off randomly. I've dropped it before today and it just now started doing this. How can I fix it or do I have to bring it in to a Apple store?

    The phone is probably broken. You will have to take it to an Apple store for repair or replacement.

  • No turning off the iPhone when its locked

    Si bien la opción "Buscar mi iPhone" es muy útil para rastrear tu celular y proteger tus datos, de nada servirá si quien sustrae el iPhone lo apaga automáticamente. En ese sentido, quisiera saber cómo evitar que se apague el iPhone cuando la pantalla está bloqueada, a fin de que se pueda utilizar la opción "Buscar mi iPhone" u otras.
    Al margen de eso, sería bueno tambien conocer sobre la toma de fotos de la camara delantera cuando se realicen dos o más intentos fallidos para desbloquear el iPhone.
    Gracias

    You cannot prevent the phone from being turned off, locked or not. Even if you could, a thief could still take the phone somewhere where there was no service or just wait until the battery died.

  • I have a Mac Book that I purchased in 2009 and all of my system updates are good and it keeps shutting off and when in use it keeps asking me if I want to shut it off... Then it keeps turning on and off on its own. What doI need to do?

    Please help!  I cannot figure out how to get the computer to stay on!

    With the information provided, I can only guess. My guess is hardware problems, either bad motherboard or RAM.
    You tried running the Apple Hardware Test from the install DVD for you Mac.

  • DlHelper turn on safe mode on its own, after uninst./relode is same

    The DlHelper plugin has today changed over to safe mode and does not show adult pages. have checked internet and checked About:config settings, they look OK. Some comments on internet about them wanting contribution to tell you how to get access?

    First, see this about not booting into Safe Mode (try a PRAM Reset)

  • My user process crash when I turn on the monitor

    I have a Mac Pro 2009 with a radeon 4870 and a Benq V2400W LCD monitor (24") connected with DVI. Since about 8 month, or about the same time I upgraded to 10.6, I began to notice that a random number of user process crash randomly when I turn on my monitor when the computer was already running. (Like when I am doing something else and close the monitor but leave the computer on). For example, I turn off the monitor, go to the grocery, come back, turn on the monitor and see Safari, Dock, Finder, WebUIserver crash all at the same time.
    At the exact time I turned the monitor on !
    It very random. I can only see one application that crash, or I can see nearly all my user process crash. I never saw any kernel panic nor admin process crash and if I don't turn off and on my monitor, my computer never crash !
    6 month ago, it wasn't a problem since it occurred like once per 2 or 3 weeks, but in the last month it occurred like 2 times a day.
    I tried to : -Reinstall OS 10.6 over my current installation
    -Reformat & do a clean install
    -Reformat & install nothing except few app (iLife & iWork)
    -Change my main HD
    -Run Hardware test for hour and hours without any error
    -Disable computer sleep, display sleep and HD sleep
    -Pray Steve Job.
    Since 5 day, it run fine but I no longer turn off my monitor. I just set the energy saving setting to 5 min. for the display and it work like a charm.
    Since a display can only receive the signal from the video card, I doubt it can make my process crash. Can it be my video card that have a "wake up" problem or it a OS 10.6 bug ?
    I have read hundred of Console lines, but nothing occur when I turn on or off the screen.
    Thanks

    It could be a problem with the video adapter, but there are other things to eliminate first. Does the monitor have a USB hub that's plugged into the Mac? Are you turning off the monitor with its power switch or are you actually removing power by unplugging the cord or turning off an outlet strip? Does it behave differently if you turn off the power using whatever method you haven't been?

  • Why can't I turn Airport on in my iMac? It turns off on its own.

    I have an iMac with leopard and an intel processor. Airport (the hardware/software responsible for my Wi-Fi) seems to turn on and off on its own.
    Sometimes when I log on, Airport is on. Sometimes after it goes to sleep, Airport is on. But sometimes, Airport isn't on, and there's nothing I can do to turn it on. It appears that this is an issue other users are having, but I can't find the resolution. I am looking for easy steps!
    I have gone to network preferences, and tried pushing that cute little "Turn Airport On" button. Nothing. I've tried deleting the locations and adding a new one. Nope. I've changed the order of the network devices. I've tried to turn airport on through that little icon in the upper right. It's hollow, and tells me "No Airport Card Installed". It's lying. It was there two days ago. System profiler tells me that there's no Aiport card installed, but it did *two days ago*.
    I admit my ignorance of Macs whole-heartedly. I bought my first a month ago - I only spent 3 hours that first day getting it on my network. The next day I spent another 3 hours getting it BACK on the network. Now I have spent 2 days trying to get it to believe it CAN get on a network.
    An Apple salesman convinced me how terrific Macs were, and impressed me with how easy they are to use. He made a crack about how inferior Dell was and how sorry he felt for me. I am writing this message on a Dell laptop. It is connected to my wireless network. It took me 3 minutes to connect it, and it never once has told me that it no longer has a network card. Neither have the other 3 PCs in my house.
    Can someone PLEASE save a poor, helpless PC user. I clearly need assistance -I read somewhere that I can run a 'script' to turn it on - but I don't know this OS so I don't understand what that entails
    If any answer involves taking my Mac into a "Genius Bar", then the "Genius" can keep it. I've never had to take an out-of-box PC to a "Genius" - because it doesn't take one to fix a PC. Please guys, save a PC user. This Mac cost more than the PC I wanted and it's worth a lot less to me right now.

    Hi, sorry to hear that you are experiencing these problems, but sometimes a new machine (be it Apple, Dell, whatever) can be defective right out the box - its not unheard of.
    If your machine came with defective hardware and is still under warranty (seems to be the case here) then you have nothing to lose taking it back to where you bought it and, if there really is defective hardware present I am sure they'll rectify the problem.
    A small note: these problems are not manufacturer-specific - its pointless blaming the manufacturer as I can assure you this happens with ALL brands. Apple supplies quality hardware and software - I know of a user who has had a machine switched on since 1987 without problems

  • JPA -- How can I turn off the caching for an entity?

    Hi,
    I have a problem that I will illustrate with a simplified example. I have created an entity:
    @Entity(name="Customer")
    @Table(name="CUSTOMERS")
    public class Customer implements Serializable {
    }I have also set the collowing properties in persistence.xml:
    <property name="toplink.cache.type.default" value="NONE"/>
    <property name="toplink.cache.size.default" value="0"/>
    <property name="toplink.cache.type.Customer" value="NONE"/>
    <property name="toplink.cache.size.Customer" value="0"/>
    <property name="toplink.cache.shared.Customer" value="false"/>And then I run the following code:
    Customer cust = em.find(Customer.class, 1L);
    System.out.println(cust);
    cust = em.find(Customer.class, 1L);
    System.out.println(cust);The problem: the second call to em.find does NOT generate a query to the database. Here's a fragment from the console log:
    [TopLink Fine]: 2007.05.11 02:55:05.656--ServerSession(2030438)--Connection(5858953)--Thread(Thread[Main Thread,5,main])--SELECT ID, SEX, NAME, MANAGER FROM CUSTOMERS WHERE (ID = ?)
         bind => [1]
    Customer: id=1, name=Customer #1, sex=MALE
    Customer: id=1, name=Customer #1, sex=MALECan anyone help me? Why isn't the caching turned off? I tried various combinations of properties. Nothing worked. I was expecting to see two queries to the database. I can see only one.
    I tried with TopLink Essentials Version 2 Build 39 and Version 2 Build 41.
    Best regards,
    Bisser

    The cache is likely turned off, but you can't tell because you are using the same transactional EntityManager instance for the two queries. The EntityManager requires its own cache for object identity and transactional purposes, as once you read an object in through the EM, the spec requires that all subsequent reads return the same instance. Only the EntityManager refresh will cause a refresh, that or setting your queries to use the toplink.refresh and toplink.cache-usage query hints.
    I would strongly recommend you use a query cache for performance, but there are of course reasons why one might not be the best option.

    is a good blog on understanding the caching used In TopLin Essentials.

  • My iphone no service when i turn off the 3g option why!?!?

    well sometimes i just use my data and turn on the 3g option but when the data is off i just turn off the 3g and its said no service why?? (sorry ,my english im from panama so well )

    Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
