Can't adjust screen brightness on my Dell Studio 1558

Question

I just recently formatted my laptop and reinstalled the operating system and after I installed some of the drivers (don't remember which one it happened after), I noticed that my screen brightness was extremely bright and I couldn't adjust it to make it dimmer.  When I press the buttons at the top of my keyboard, it shows the dial going down and up but the actual brightness doesn't change.  I've also tried going into the display settings in Windows and moving that bar up and down doesn't adjust the screen brightness as well.  Having my screen bright not only drains my battery, but is almost uncomfortable to look at at night.  Any help figuring out how to fix this would help.  I've tried updating the BIOS as well as the chipset drivers but no luck.  Any help would be appreciated!

Unfortunately, that didn't work :(  I tried installing the Quickset that was on the drivers page as well.

Hi blee92,

Let’s try few more troubleshooting steps to resolve, as well as isolate the issue:

Check if vertical lines appear in BIOS screen (Restart the computer and tap F2 on Dell logo).
Also restart the computer and check the display in Safe mode (Restart the computer and press F8 on Dell logo and select Safe mode)
Run the diagnostics on the computer (Restart the computer by holding the power button and D and wait till the LCD test completes) and let me know if you observe the brightness on screen during diagnostics.

In case the system has active warranty, please private message the system service tag, contact number and registered owner’s name.

There was a similar thread a couple of weeks ago and as far as I remember the solution was to reinstall the video drivers. Create a system restore point and give it a try

Before I do that, I just want to check one more thing.  Windows is flagging that there is a compatibility issue between ST Micro Screen Detection Sensor and this version of Windows.  Does this have to do with my issue?  If so, can you lead me to the correct driver for my computer?

I am not familiar with your system but I just googled and found this thread en.community.dell.com/.../19390317.aspx

Hi Rajesh,

I am currently having the same problem that blee92 was having.

I tried the recommendations that you suggested to him/her but they did not work.

Is there any other suggestions that you might have in order for me to be able to adjust my screen brightness?

Thank you!
