Hi,

Even I am facing the same problem (got my 1464 laptop just about 2 weeks back). Did you manage to correct this?

I read somewhere that installing an update for BIOS would fix the problem - in fact, for me, it aggravated the issue even further. Now, after installing the update (I think it was 1464_A05.exe), the brightness controls are acting very funny. On pressing the 'brightness down' button, nothing happens, but after pressing 'brightness up' - 'brightness down' starts working. Also, the problem of increasing brightness still persists.

In case you manage to get any fix, please do let me know as well - thanks a lot in advance.

I have the same computer line and I also had a similar problem. The solution that worked for me was: go to start menu, control panel, Intel Graphics and multimedia, energy, choose energy functions, choose "with battery power" (for the option: configuration of the energy plan for graphics), and  disable (untick) the option "energy saving technology for the screen"...

sorry about the bad translation but my options are in spanish, so check yours in your language!

I hope it helps!

Thanks a lot for input  - it indeed works (though I had already got this solution from other website). But, do you need to set this everytime you reboot your machine? If I uncheck the 'energy save tech ...", it gets "checked" every time I restart the machine. Did you manage to get around this?

Nevertheless, thanks a lot for replying back. It certainly is most useful.

I don't have that problem, and actually, it shouldn't change the behaviour everytime it boots.  However, I do know that this Intel graphics driver has other problems and I am hoping Dell to release a new version soon... I am having right know a problem with it, which is my own "headache", and I certainly hope it can be solved ASAP with a new driver version.
