Why won't mt my color settings stay after I reboot my new Inspiron ?

I have new Inspiron 15R N5010 with Win7-64bit and when I go into the Intel Graphics and Media Control Panel to change the Saturation setting slider from 0 to 20+ and then apply - ok it stays and everything fine. But if I reboot the laptop or shut off then turn on the setting defaults back to the dull colors. But the odd thing is the slider stays always at the setting 20+ but the colors are like if the slider control button was at 0 again. Why doesn't it not just put the default the slider back to 0 instead of keeping it at 20 but with the colors repreasenting a value of 0 ?

So what I'm saying is that the slider at 20 but the colors look dull like if they were still at 0 setting. To fix this I have to click once on the slider setting and it will change right away with the 20+ setting. I hope I don't sound to confusing.

I've installed the latest driver too. So what can I do ?

Not sure if this would affect anything but I disabled all of the startup items in system configuration it was taking to long for the pc to bootup. I really doubt that would cause my problem I'm having now


PS I have another quick question, It said in the discription that my laptop with a reg 6 cell battery would last 4 hours and 2 mins. The most I can get is like 2 hours & 45mins with internet use and movie ?

 

Completely purge Intel drivers, and try the Dell ones first. Then try the Intel ones if Dell's does not work.

As for the battery life question, those are always ambiguous numbers, tested probably with wifi off, screen completely dimmed and idle.
