Why the brightness of the screen on my Tablet keep changing suddenly?

Why the brightness of the screen on my Tablet keep changing suddenly?

Some tablets have a light sensor Adaptive that detects the actual brightness in the room and adjusts the brightness of the screen accordingly.  If the light hitting the sensor is constantly changing, or if you accidentally cover this sensor with your hand or thumb, it can fool the sensor into thinking that you are in a room dark and it will lower the brightness on the screen.

In Windows 8, the Adaptive brightness setting is enabled by default.  You may be able to prevent unwanted changes in the brightness of the screen by deactivating the Adaptive brightness setting.

1. on the home screen, type Control Panel , and select the control panel.

2. set the display: drop-down category menu

3. Select the material and audio.

4. Select Power Options.

5. Select the link Edit plan settings on your current power plan

6. Select change advanced power settings

7. develop the display

8 expand enable adaptive brightness

9. set the setting to Off , then select OK.

    I currently have Firefox 9.0. Why the start page for firefox keep telling me that I don't have the latest version?

    You may need the old start page. Go to Firefox > Options and in the pane general, under Startup, click on restore by default. The page you have probably (http://google.com/firefox) only served to 3.6 (and tells you you are outdated), but some users seem to have gotten stuck on it after updating to Firefox 4 or upper version.

  • Why the screen saver does not work in the two screens?

    I have a monitor connected to my laptop using the VGA connector.
    Laptop LCD is set as the primary display and the additional monitor is defined as the extended desktop. When the screen saver appears, it shows on the main screen. How can I make it work on both? (without setting the external display as a clone of the hand).
    The OS is Vista Home Premium

    Thanks for any help!

    In dual screen extended mode, Win7 screen saver stops working after unpluging external monitor

    I have problems of this kind.

    I have listed what I've done to illustrate how to reproduce this.

    My OS is win7 32 bit.

    The replication steps are

    1. start on OS with integrated display (it is the system of n. b.)

    2. attach the HDMI (external monitor).

    3. turn on the extended mode and HDMI monitor as the primary device.

    4. set the screen saver 3D to be active and preview.

    Screensaver 3D drawing now works on the main screen.

    the secondary monitor (built-in monitor) working with black screen.

    5. hot unplug a HDMI monitor.

    6. the display of the 3D screen saver is changed back to the built-in screen.

    7. BUT the drawing of 3D on the built-in screen screensaver is STOPPED (= NOT updated).

    8 move the mouse, built-in monitor escapes from the idle screen status (operating system is still alive)

    Is this an OS behave as expected?

  • Why the length of film does not change when I remove Vista Movie Maker clips?

    You have not answered my other question.  I get an error "does not fit" when you publish a movie on dvd. I deleted half the clips in the storyboard and length does not change. I always get the error "will not fit". After I saved the project. It seems that it becomes the length of the imported clips not what is in the table of Storyboard. The length of the table of Storyboard is only 01:30, but the length in the window shows 02:42 that is causing the error. It seems to me that it should use the length of the table of Storyboard because it's what makes the final video on dvd.

    Yes... adding or removing items from the timeline should change the duration of the project.
    The files in your component collections have no effect on the duration of the project.

    I suggested that you publish in the movie .wmv format to see if the version with clips
    removed would still last for 02:42.

    As I have said from the beginning... creating several small projects may be your solution.

    I'm sorry that my suggestions seem redundant to you. Perhaps you could find assistance elsewhare.

  • Why the screen "post preview" in flash cs5 shows the part of the animation and then turns blank?

    Hi I'm creating animation frame by frame in photoshop.

    I import photoshop files into flash using

    FILE > IMPORT > IMPORT TO STAGE

    I used to be able to preview or 'test line' my movie easily by clicking on:

    FILE > PUBLISH PREVIEW > FLASH

    I could watch the animation in a loop and see where improvements are needed. Now, flash struggles a lot with the files, takes a long time to load the preview, when that happens, it shows me maybe a third of the animation, running on empty and behaves as if all my frames are completely empty. I can't see on my main work no more later.

    Anyone know what is happening? I keep restarting flash but the same problem persists.

    Thanks in advance for any help or suggestion

    It's more 100megs of images, then you are probably hitting a limit of flash cs5/system.

    are you using a channel alpha and overlay of some of these pictures on another?
