Laptop contrast/color temperature?

I am trying to calibrate my Dell Vostro 1510 laptop monitor. I have a Spider3 calibrator, and according to the instructions, I'm supposed to be sure my contrast is on default setting, and to change the color temperature to 6500K or equivalent. I've searched the internet, asked friends and looked everywhere on my computer to do that, and I can't figure it out. Any and all help would be greatly appreciated. I'm in photography school and I have about 24 hours worth of photoshopping photos to do within the next week, and my monitor colors are so far off that even attempting to edit anything now would be a serious waste of time and prove to be disastrous.
