Late 2008 MBP 15" not charging but runs off power adapter.

Question

I've tried a known good adapter and have the same issues. 
The power adapter light does not come on, but the machine indicates it is on AC but shows (not charging)
Sys Profiler information for power indicates:

I also have classic SMC symptoms (noisy fan, intermittant keyboard lights) and have tried SMC reset 2-3 times but am unsure if it has worked as power issue remains (another classic SMC symptom).
Any suggestions would be appreciated!

Answer 1

The battery conditions look decent, have you gone through the Troubleshooting MagSafe knowledge base article?
If nothing there helps, might be a good idea to make an appointment at an Apple genius bar and have the charger and computer checked out by the techs.  See if something else is wrong, such as the charging circuitry that doesn't show on the system report.
