Using my '09 MBP while charging...

In a nutshell, when using my '09 MBP while charging on a powerstrip, there is an awful fan noise. So I got to thinking... since our house is suge protected anyway... something like a whole house surge protector. (My dad told me about this one time...) I just plugged my MBP straight into the wall bypassing the "power strip", when I did that, the buzzing noise was gone.

Could it be possible that the powerstrip and my MBP didn't interact with each other positively?

The power strip could be defective. There shouldn't be any compatibility issues between any power strip and your adapter.

Thanks, everybody.

I didn't even think that the powerstrip was the actual problem. I am so glad to know that my MBP wasn't the problem as I originally thought. I don't know how old the power strip that I use to use actually is. If other things start to "act funny", I'll know for sure.

Thanks, everybody!

I actually wanted to add - test it by seeing if other devices and what not act up when utilizing the same power strip. In any case I hope everything with your MBP is fine, as it seems to be.

Surge Protectors/Power Strips are a huge pain and I don't understand them at all, lol. At this point I basically find it acceptable if it simply gives off power to the devices plugged into it. I suppose I'll regret that later on in life.

Where I live we have frequent thunderstorms or power outages. I've had a TV, audio receiver, and a couple surge protectors taken out by a electric surges. Of course, the protects that died did their job. Needless to say, all electronics are on surge protectors or UPSs.

I'm glad the rest of your devices made it out safe and sound.

I have a "Surge Protector," it's a power strip and it's indicating that it is "Protecting" what is plugged into it but what I meant was that I am so ignorant when it comes to electrical stuff. I basically bought it for the amount of outlets, not for what it advertises to protect against and what not.

I omitted Joules from my memory after Chemistry in High School.

My "Grounded" light is faded, that must be bad, right? It still says "Protecting." :)

Forgive me if I'm wrong... But isn't Joules a physics thing...?
Both actually. We are using it in some of our chemistry equations as units for calculating energy from reactions and such. I also remember using them in physics back in high school (luckily my major doesn't require me to take any physics classes).

Ok, I haven't gotten to the more advanced stuff (I don't plan to either, haha).

Low voltage can be harmful too.

Since our whole house... I believe... is surge protected. I just plugged it straight into the wall outlet. Though, as of right now, I have also changed where I placed the plugged the charger into the power strip socket, I just switched the place where I plugged into the power strip. Which pretty much, to me, means that possibly the power strip is slowly dying. Though, our phone, which is likely plugged into the same power strip is fine. (As far as I know.)
