My screen keeps dimming on an HP Pavilion g notebook with Windows 7, why?

[Amy1326]

While I'm on the internet, my screen dims randomly depending on the website. Sometimes it would go to normal brightness but then right back to really dim. It would get so dim, I could barely read anything on the screen in a dark room. I can't adjust the brightness with the F2 and F3 keys and I've tried adjusting the power plans' brightness and nothing changes. How can I keep the screen from dimming all the time?

mine just started doing the same thing today. it's really, really dim. idk what to do..even other programs (ms word, desktop, etc) are dim..the whole screen, not just internet pages! i can barely see this page.

so far, restarting has worked, but this happened to my husband's dell, n resetting only worked a couple times..then it went dim permanantly..so be careful, and back your stuff up!

Mine started doing the same today. 

It seems to dim when a webpage loads. Once the page is loaded, it fully brightens again. 

If anyone has any info as to why this has started happening, or how to fix it. Let me know. 

Laptop is still under waranty, but it doesn't seem worth the hastle sending it back when I fly to Ibiza in 3 hours.

Was your video card built by AMD/ATI?

If so, the Vari-Bright feature must be on. To fix this go to:

1. AMD Vision Engine Control Center (or AMD Catalyst Control Center)

2. Power

3. PowerPlay

4. Uncheck the "Enable Vari-Bright" option.

and that will fix your problem.

My video card is AMD but I couldn't find that center on my computer. Is there another way to access that feature? 

[3m2vinatohr04]

You may download the AMD Catalyst Control Center (AMD Vision Engine Control Center on other laptop)

at the AMD/ATI website

here:

(change hxxp to http, this is to avoid web spiders/bots)

Thanks, it fixed it! It was the vari-bright feature, I'm so glad I finally disabled it!
