this works for Dell monitors with a similar problem: shut down, turn off monitor and pc, turn off at wall socket, and remove power plugs from wall socket. wait about 30 seconds. plug back in, turn on, and all should be well? I have used this 3 times on a Dell PC with a Viewsonic monitor.

This has worked three times on a Dell PC: shut down; turn off monitor and PC at wall socket, unplug wall sockets, wait 30 seconds, plug back in to wall socket or power board, turn on, all should be well?

• Verify that the power outlet you're using is good and your power cable is firmly connected to the wall outlet-if using a surge protector, be sure that it's firmly plugged into the wall outlet. Also, try temporarily plugging directly into the wall outlet to eliminate any issue with the surge protector; plug a different electronic device into the same wall socket to make sure the socket works, and also try the iMac's power cable in a different wall outlet.
• Make sure the computer's power cable is firmly connected to the computer.
• If any external devices are connected to your iMac, disconnect them and try to turn the computer on again. If the iMac will power up when those devices are removed, but not when they are connected, contact the manufacturer of those devices for assistance.
• Try resetting the iMac's SMC
• Remove and reinstall the SO-DIMM memory modules, located in the bottom of the computer.

• Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
  

  1. Shut down the computer.
  2. Unplug the computer's power cord.
  3. Press and hold the power button for 5 seconds.
  4. Release the power button.
  5. Attach the computers power cable.
  6. Press the power button to turn on the computer.

Shut down power, unplug from wall power socket, wait a few minutes then plug in and try again. This is the reset process, to load codes into drams properly when the machine is no longer in standby mode.

This is because the power switch operated the socket that your TV is plugged into. Unplug it and plug it in another socket that is not operated by a switch. Appliances should not be plugged into a socket operated by a switch because of the inconsistency of power to the socket. Lights are about the only thing that should be plugged in.

The sparking has probably caused your circuit protection inside the AC adapter to turn off the current.
Also, when you are plugging an adapter in,,do not have it plugged into the wall power outlet when plugging into the laptop,,,plug into the laptop first and then plug into the wall.

Is the battery charged? What does the battery indicator say? If you are using it in the car, is the power cord connected and working properly? If it is working correctly, you should see a lightning bolt symbol over the battery bar graph showing that it is connected to an external power source and that it is charging.

Try to check the capacitors of the motherboard, maybe some of them are damage, they can cause this kind of problem
