    Guys,

    Recently my macbook pro 13 inch mid 2014 model (macbook pro 11,1) has become super slow. Activity monitor shows that kernel_task is using almost 250% usage and makes my macbook super slow. Also the fans are always blasting on full power. I tried resetting SMC also PRAM which did not help. I also did a clean install of el capitan and again tried resetting SMC and pram. Problem is the same. What might be wrong with my computer? Do I need new logicboard or I/O? Running apple diagnostics shows that "There may be an issue with the System Management Controller (smc). Reference code: PFM006 and issue with power management system reference code: PPN001

    Try running EtreCheck and posting the results here. http://etrecheck.com
    Maybe someone will be able to diagnose your problem from the results.
