Power light occasionally not coming on - get it looked at?

[rochow]

Occasionally (< 5%) of the time when the power cable is connected it'll be on power, but not charging. Given the computer knows it's connected this seems like a software thing.

We had a similar problem with another MBA, though it was on a timeframe of about 1 day. Had problems with the light, had trouble waking it, within 24 hrs it wouldn't turn on at all. Motherboard from what I understand was replaced by Apple.
This has been going on for quite a while though and no issues waking it up from sleep.

As the computer is going out of warranty soonish, should I get it looked at/is it a sign of a potential component failing, or is it fine to ignore?

If it's still under warranty, get it checked. Things don't get better by themselves. Also, check for cruft in the magsafe socket, and on the plug itself. Anything there could prevent the contacts from making good connections.
