Title:

Always needing to reset SMC + Fans running at full speed

Text:

For reference, I’ve done some troubleshooting and replaced DC-in at [post|539482].

'''Latest steps to replicate issue, ''consistently'':'''

# Failure to boot up post shutdown/sleep/close lid.
# Initiate force shut down by holding power button down.
# Power up with power button again. Fans will run at full speed. MacBook can be used this way but it runs at full speed constantly.
# Not wanting to use the computer this way, I force shut down by holding power button down. And then reset SMC by holding CTRL+OPT+SHIFT+POWER buttons down for 10 seconds.
# Power up with power button again. Fans run at normal speed. At this point '''if''' the MacBook goes back into state #1 (i.e. shutdown/sleep/close lid), I won’t be able to “power up” again. I’ll then continue with step #2.

'''Troubleshooting Summary:'''

1. Replaced DC-in, ok.

2. Wall socket checked out, ok.

3. Clean installation of latest OS, ok.

4. Charger using original one that came with my MacBook, ok.

Please help!
