    Cannot increase the brightness of ACER ASPIRE 5750-6845

    The brightness key of ACER ASPIRE 5750-6845 is not working. I had tried to increase that but it is not responding. I am bit stuck with very low light. I want some help here to increase the same. The same issue is with the volume key also. For that I hold the functions key and the f keys from the top to increase brightness and volume.But both are not working. I don't know what really happened to the system. I had given that to my friend for using.

    This is a keyboard problem. You have to update the drivers and that will fix the issue. You can find the same on the official site of acer. But if you are unable to find the same then you can try some other usb keyboard which has similar key settings. You can add that and reduce the brightness. There are few brightness control applications available that can also help you to increase and decrease the screen light. There are also chances that the keys are damage.

    It is a hotkey issue. Almost all laptop comes with a set of hotkey settings through which you can use the function keys to manage the brightness and volume. You can fix them by adding the hot-keys drivers in your system. You can find that on the acer support site from where you have to locate official drivers page of your laptop model. Download the hot-keys drive and install them. Then try to use the and it will work.
