Hi, My mac has been acting weird lately. The MagSafe adaptor's light sometimes goes off even the mac continues to charge. Because of that, today I tried to reset SMC. But the MBP didn't respond (The MagSafe light didn't change and stayed green) when I pressed shift+control+option and power keys. Any ideas?

Update: I tried to reset again. This time also the MagSafe light didn't change. But when I turned on the MBP, it started with fans screaming and the screen brightness was very low!! I brought a light near the ambient light sensor and it didn't respond to the light. I turned off the computer and started it again, and then the fans and screen brightness were ok..

Update: I followed the same procedure again. Fan and brightness issue disappeared. But the mac still doesn't go to sleep if I leave it idle.
