Side effects with reseting PMU?

[Sweener88]

Hi i want to reset my pmu to fix heat issues with MBP, is there anything that could be wrong with doing this?

Not really but it probably won't help the heat issue.

Having said that, you can damage the logic board if you reset it multiple times between restarts.

Seriously? Is that any logic board or just the MBP?

 

[mad jew]

That's any logic board. FWIW, the consequences are still pretty rare but don't do it all the same.

I've done it twice accidentally, with no dramas.

I was thinking of doing it intentionally because I am getting tired of waiting for Apple to fix the whine on my MBP…

Apple technicians are pretty good at working out whether a machine has been tampered with. I wouldn't bother.

I don't think holding down the power switch while the battery is out would be considered tampering.

Now if I used an X-acto knife to make a tiny cut across some circuitry, well then yeah.
