Glowing T Key (Changes with Temperature)

[Chrissj]

I just recently noticed my T key is a lot brighter than every other one and that the u, i, and o keys have little to no backlighting. I kinda figured it was something I never noticed till now, however I just realized something that maybe that wasn't the case. I tried to take it with a picture, I turned off the flash but the camera doesn't seem to be able to pick up the difference.

I start up a game, I have a temperature monitor on. Once the CPU reaches around 80 degrees the keys appear uniform. Stop the game and when the CPU reaches 75 the T starts to get brighter and by 65 its at maximum brightness. It's kinda hard to tell but it seems like the T key actually darkens when it gets to 80, not the other keys matching the brightness. What is probably more likely is that they meet halfway.

I don't plan on returning the laptop because of this problem since I don't mind having the keyboard fully off, however if the problem doesn't go away, I will definitely bring it up should something else happen.

I was wondering your thoughts on the issue? I'm guessing its not a self repairable issue.

Btw: it is several levels higher than the other keys at each setting. The first few levels make it look like only the T key is on.

Also I noticed that it is viewable on a larger screen, heres a picture of what I'm talking about.

Please use TIMG tags instead of IMG tags, it will create a thumbnail of your image, as currently your image is quite big on a 1920x1200 resolution display.
It makes reading your post harder.

Example:
now it is like [ IMG ] image [ /IMG ]
it should be like [ TIMG ] image [ /TIMG ]
The space between [ and IMG/TIMG is intentional.

EDIT: redundant post.

As soon as I posted it and saw the result, I went through several edits to fix it

some of mine light up at different intensities also, though not that distinctively. I never worried about it.

I see the bright T, as well as the dark U and I.

I was always under the impression the each key didn't get it's own LED. That is, there aren't 30+ LEDs under the keyboard, they get shared. That would explain this if it is correct. Maybe your LEDs just aren't as evenly spaced as they are supposed to be?

The real question is, why is your keyboard light bright blue? Mine is white.
