cannot change screen brightness

Hi,

I bought a dv3t-2000 two months ago and recently i installed windows 7 and i just realize that is not possible to change the brightness on the screen, is always the same. I have tried changing the power plans, I've upgraded the BIOS, but so far is not working.

I will appreciate if anybody help me with this issue.

Thanks in advance .

Re: cannot change screen brightness

I tried all the drivers from hp but none of them solved the problem but after searching in the web i happen to find a solution to the screen brightness problem.... now everything is working the way is supposed to.

It was just matter of installing a new version of the "Mobile Intel(R) 4 Series Express Chipset Family" from Intel, the driver supplied by HP seems to have a problem.

Thanks anyway.

Re: cannot change screen brightness

Not a very helpful answer "dummycakes."  This has nothing to do with the graphics driver.  Most of the HP laptops have a keyboard Function key and you can press FN + F7 to decrease and F8 to increase screen brightness.  I am getting ready to install Windows 7 myself and would like the answer to this also.  My guess that is what Maurice is talking about.  I thought I saw somewhere that you need to install the latest drivers for the Quick Launch buttons and keyboard although I don't see a keyboard driver listed anywhere under Vista or Windows 7.  There are Quick Launch drivers for both.

Re: cannot change screen brightness

Re: cannot change screen brightness

This solution worked for me as well. I had already downloaded the one on the HP site first, so I was perplexed.  I have probably suffered retinal damage due to my very bright screen prior to finding your post.  THANK YOU!

Re: cannot change screen brightness

Yeah, that worked for me as well. I could not change the brightness, be it from the keyboard or from the power options.

I uninstalled the previous drivers and then downloaded and installed the drivers from the download center at the Intel site.

Thanks. Smiley Very Happy

Re: cannot change screen brightness

See the above - the update you need is usually listed under Windows Update > Optional updates.

Re: cannot change screen brightness

Yeah, this worked for me too. I have a dv3-2155mx and had to uninstall the HP modified driver before I could install the intel driver. At least now I can adjust the screen brightness

 

C'mon HP, fix this crap and fix the quick launch issues!
