820-3476 - Not Turning On

Hello,

I have a MacBook Pro Retina here where it does not turn after going to sleep for a long period of time. The only way to get it up and running again is if I disconnect the battery and reconnect with or without charger. The power button does work as I can turn it off forcefully or gracefully and able to turn on with the button.

Where should I begin troubleshooting this?

Try PRAM reset mfirst.

Check SMC_LID signal when doesn't want to resume from sleep.
Is PM_SLP_S4_L still high then?
