MacBook Pro Charger Light

1. Robert Peirce - 4 May 2008

   Frequently, when my MacBook Pro is fully charged, the green light on the plug goes out. Re-plugging turns it back on, but why does it go off? Help says it should either be amber or green. Could one of the connectors be oxidized and should I worry about this?

   I just realized I should probably have posted to the portable group as well or maybe even instead.

   Reset the SMC.

   I typed "reset SMC" and just "SMC" into OS X Help and got back

   No pages with your search words were found

   I then "googled" "reset SMC" and got a reference to an Apple Support Article. Interesting.

   For an Intel Mac portable:
   - remove AC adapter (and other cables)
   - remove battery
   - with _no_ power source attached, hold the power button for 5 seconds - restore battery & AC adapter

   This is the cure for many power & sleep issues. It may also resolve "missing" hardware problems (e.g. the system doesn't think it has an Airport card or firewire port).

   I'm having the same problem, but it happens when I move the cable while charing. I guess it's some kind of wiring problem, but it charges fine.

   For what it's worth, the green light on my MBP's charger stopped working in 2006, soon after I got the computer. I guess it was under warranty but it worked fine, so I didn't bother getting it replaced. It still works, so unless there are other symptoms it's probably not significant.
