RF411 Speed Mode Brightness

by LKarum / January 16, 2012 2:17 PM PST

Hello there folks,

I have a RF411 notebook and lately I got a problem. The brightness change that happens when you change to Speed Mode (fn + f8) isn't happenning anymore. I tried updating the NVidia graphics card drivers and the Intel graphics driver but it didn't work.

Any clues of what it might be?

I use Windows 7, by the way.

I'm sorry for posting again, but I didn't find any edit button.

I also tried reinstalling Easy DIsplay Manager and it didn't work as well.

I have the RC512

And it's all good. But if one installs something other than the factory load I bet this could happen. This ought to be good. I mean, I wonder if Samsung supports a self installed OS?

Oh, the Windows 7 I use is the default OS, I didn't change it.

Just tried Fn+F8 here.

While I see no reason to move out of normal mode here, I put it in speed mode and was able to adjust the brightness fine. There is NO change in brightness because I have the same level for AC and Battery power.

Be sure you know the brightness does NOT change just because we change modes. It changes because of how we set it.

Put another way. In Speed Mode if you can adjust the brightness with Fn+ Up or Down, then it's still working.

There's something different now

Hi and thanks for the answer.

Here, when I switched to Speed Mode, there was a difference in the monitor. I used this resource for some months until somewhy it stopped working.
It was particular noteworthy when showing images with strong colors. I'm not sure if only brightness was changed but It was clear that the image really got more "alive".
