Q: SMC reset has not restored the fan / display / battery status back to normal. How to restore these?

Post SMC reset (I had performed SMC reset as my display had started dimming and boot disk was not getting recognised). The Fan is running at full speed. Display dims automatically and the power adaptor does not show the charging light nor battery status on right hand shows percentage (shows X inside the battery symbol). What needs to be done to get these setting back.

MacBook Pro (13-inch Mid 2012), El Captain
