    Random brightness change problem


    Dear readers,
    i have a smal probleem with My new Acer tablet. The brightness of the screen randomly changes.
    i did some googling and i learned the tablet is able to auto adjust the beightness. I found a sensor on My tablet and did some testing by shining on it with a pocket torch and saw with more light the brightness increased. How i want it off. I Tried switching off the adaptive settings bit it didn' t work..
    anyone soms advise?

    Looking at the link below, it looks like there's a separate setting for this on your Acer tablet. You would want to uncheck the "Display Power Saving Technology" option.

    Cool feature though! Can you adjust how the fucntion operates, as in the sensitivity of it?

    Not always with adaptive brightness.

    You could manually set your brightness and dim settings using the features in the tutorial below instead though.

    I was just wondering, cos I can adjust the sensitivity of it on my iPhone, so that it never gets any darker than 60%

    I Tried the Intel configuration thing but i could'nt find it. I Tried Search terms 'intel' and 'graphics' but both no results.

    Sebas,

    You may need to update your Intel video drivers. If you like, you could use the Intel Driver Update Utility to have it automatically find the latest Intel drivers for you.

    The Intel Control Screen usually shows up when you right click on the Desktop, in the popup menu. It should say something like "Intel Graphics Manager" or something. I'll check my laptop and see if it has an Intel graphics card... No, I have an ATI card in there.

    If you download the latest drivers for the chipset as Mr Brink says, it should show up
