Apr 23, 2015 8:58 AM in response to deathinkyby spudnuty,"my magsafe charger sparked and turned off my macbook"
Yes that would be bad and could have easily damaged the SMC chip.
"did i screw somthing up that i need professional help"
More than likely. If that chip is damaged, that could mean a logic board replacement.
Try a hard reset. Disconnect the battery (open the bottom and pull the connector off. Use your fingernails.) and power adapter. Press the power button for 1 minute. Let the computer sit for 5 minutes, Reconnect and try to start up.
No? - Go through the same procedure and try to start without the battery connected.
The addendum to this would be to try a known good battery.
Basically it's the SMC reset w/ a battery you can remove.

Apr 23, 2015 9:11 AM in response to deathinkyby PJ'sPal,Can you use Istat to control the fan speed?
I think it works with the SMC if I recall correctly.
Also, 102 degrees Farenheit is OK.
Do you mean 102 degrees Centigrade?
I would think the high fan speed would keep it to the lower level of 102 degrees F.
Spudnuty may be right that the spark damaged the SMC controller. Hopefully not.
There may be other fan controllers, other than iStat, you can try to use depending upon the age of your Macbook to control the fan.
Logic board replacement is probably an expensive option. Better to buy a used or new Macbook pro.

Apr 23, 2015 11:22 AM in response to deathinkyby OGELTHORPE,Try running an Apple Hardware Test. You will have to use the original install disk with the AHT instructions written on it:
https://support.apple.com/en-us/HT201257
Note that an error free AHT is not definitive.
You probably will have to go to an Apple store genius bar for a FREE evaluation.
Ciao.

- On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
- Release all the keys and the power button at the same time.
- Press the power button to turn on the computer.
On MagSafe power adapters, the LED might change states or temporarily turn off when you reset the SMC.
On Mac notebooks with removable battery
Older MacBook and MacBook Pro computers have removable batteries. Learn about removing the battery on MacBook and MacBook Pro.To reset the SMC:

Apr 27, 2015 9:36 PM in response to deathinkyby spudnuty,Did you try the "hard SMC reset"?
Is the battery charged?
Yes - attempt a reboot running on only the battery.
Problem continues - Disconnect the battery and attempt a reboot with only the charger.

Apr 28, 2015 1:12 AM in response to deathinkyby PJ'sPal,A couple more dumb questions -
Is the new mag safe adapter the exact same model and current output as the old mag safe adapter?
The adapters often look the same. Is it the new adapter an OEM Apple adapter or an aftermarket adapter?
If not, I guess I could imagine a higher current output or a higher output voltage maybe causing a situation with the SMC.
