    FN keys doesn't work to reduce brightness

    My brightness is at maximum and it's hurting my eye badly. I've recently sent my laptop to be reformatted due to many problems and my laptop brightness was at its maximum. Asked the guy for advices and he say there's nothing that can be done. I used to click FN + up/down keys and it work. OR i will go to power options and change the settings, but now both actions doesn't work. Please help me as it really hurts my eye. Thank you

    Hi michelewjy,

    Welcome to Vista Forums.

    I recommend you go to the laptop manufacturer's web site and find the drivers, firmware, and/or software appropriate to your graphics card and your monitor and your version of Vista and download them and update your system with the revised versions. Let's see if that helps. This may also be related to the SFC problem in your other thread - so I will check especially for anything that seems to apply to this issue.

    I hope this helps. If not, post back and we'll try something different.

    Good luck.

    I've found my laptop model which is Lenovo3000 G430 and I found the website to download the drivers, but I'm not sure which is it. Can you please help me? I was wondering other keys are working fine such as volume, but only the brightness key doesn't function. Thanks.

    Do you have an Intel or NVidea graphics card? There's a video download for Vista 32 for each of them depending on which you have. It's either Intel Graphics Driver - Lenovo or NVIDIA Display Driver - Lenovo. But I don't know which from what information you've provided.

    Download Belarc Advisor Belarc Advisor - Free Personal PC Audit and it may assist you in idenifying what you have on your system.

    There's no keyboard driver I could find, and even if there were, I don't think the keyboard is the issue - but rather it is the graphics card driver, the graphics card itself, or the monitor. Otherwise you could control it with power options and that isn't working either and has nothing to do with the keyboard. All we can really do is update the graphics driver - the other two are hardware problems. It might also be a general system problem - but that will take some time and effort to trace down.

    I hope this helps. If not, post back with where you are stuck or what happened (or what didn't happen) and we'll go from there. Perhaps there's another setting somewhere that can control brightness on your computer - I'll check the site to see if I can find anything.

    Good luck!

    Hi michellewjy,

    That's excellent news. It was my pleasure - I'm glad I could help.

    Now your eyes won't be straining so much - I know how that can be as I had a bad monitor once with essentially the same problem (but drivers didn't work and that needed to be replaced) and it was terrible until I did that.

    Don't forget to close out the thread by clicking the far right triangular icon at the top of your post and typing "solved" in the box and submitting it. The moderators will notice and put a green check next to the thread title. That way others seeking answers by searching the forums will know that this thread contains a solution to the issue identified in the title - and people seeking to help will not waste time checking out this thread since it has been resolved. Actually, nevermind, I'll do it for you.

    And welcome to Vista Forums! Now that you know where we are, bookmark the site and post anytime you have further questions or problems or if you just want to browse and learn (especially the Tutorial section offers some excellent advice on a wide variety of topics) or even if you want to try to help answer a question if you happen to see one where you know the answer and it hasn't already been posted. While it most likely won't be me the next time (though it might), there are many very skilled, experienced, knowledgeable, and friendly people here who, like me, volunteer their time to help others and one or maybe even several will respond to your post to assist you. While there are other forums on the web that do this sort of thing, you've now found what I think is the best (and I've posted in and/or checked out quite a few) so don't lose this link - you never know when it might come in handy again.

    Good luck and best wishes.

    P.S. Please read my signature below and if it applies, follow the directions.
