I *just* got a MacBook pro, and the keyboard backlight is behaving very strangely. The light, even in dark light, will randomly turn on and off. Sometimes I get the backlight, but most of the time it remains dark. Has anyone had this problem, and if so, is this an ambient sensor issue or keyboard backlight issue? The screen backlight seems to stay pretty well, so I'm guessing there's something up with the backlight. Oh, and if it is a keyboard backlight issue, is it something that can be solved at an apple store while one waits, or would Apple have to keep it for a few days? As a side note, it had this problem before the MBP keyboard firmware update, and after.
