Q: Macbook Pro keyboard wont light up

Back on!! They must have far too much time on their hands... I like it tho, cute on a stick!!

It does not happen on battery, and does not happen on the power cord that came with this MBP. The keyboard does not light, and hitting either the brighter (F6) or dimmer (F5) button makes the keyboard backlight icon appear on the screen but it's greyed out with a circle with line through it symbol under the icon for the backlight and above the marks where it normally indicates how intense the brightness happens
I have in the past had a similar problem where the internal speakers would not work, hitting any of the speaker buttons would show the speaker icon on the screen, greyed out, with a circle with a line through it between the speaker icon and the marks showing how loud it is. In addition, when I went to the System Preferences while this was going on and I looked at Speaker, it said I did not have an internal speaker installed. What fixed this temporarily was flashing the PRAM, but it would come back again at random times.
The keyboard light problem always fixes itself though I haven't figured out when yet (maybe when I unplug the old power cord? maybe with time?) so I haven't needed to try flashing the PRAM. Next time though I am going to check in System Preferences to see if it thinks I don't have a keyboard installed or something. (I mean, the keyboard *does* keep working, but we'll see.)

The reason why it isn't working in areas with natural light is that your computer KNOWS you don't need it. To change this, so you look super fly with your lit up keyboard, (and unnecessarily drain your battery) head on into your settings, and uncheck the selection that says "Adjust keyboard settings in low light". Then you can look super cool at Starbucks drinking your tea latte with your lit up super fly keyboard, in the middle of the day.
Hope this helps!
