If this answer is acceptable please remember to return and mark it. Some symtoms of a dead logic board are as follows: No chime. The first clue I had that anything was wrong occurred two days after the storm when I went to turn on my AC and nothing happed. without causing any bangs, fires or smell of burning materials.

No other appliances were damaged but apparently the wet grass allowed current to enter the outdoor AC unit, blow up it, the furnace and the thermostat. I had a cascade failure of my home heating and cooling systems this spring due to a nearby lightening strike in a thunderstorm. Since so many essential components are housed in this part of your computer, the cost can be anywhere from 500-1,100. However, logic board replacements on MacBooks that are no longer under warranty can carry a substantial fee. If you had a home power issue your homeowners insurance may cover part of your repair. If your MacBook Pro is still covered, you can expect to pay 299 plus tax for your repair. Have you tried escalating the claim with Apple?

Was there an unprotected power surge that destroyed the machine? I find it unusual that Apple wouldn't make an allowances for a machine as near to still having a warranty as you state. any system of multiple parts could suffer a cascade failure. Such a failure may happen in many types of systems, including power transmission (you may recall reading in the news that many early blackouts were caused by a power cascade from a single blown transformer), computers, home heating and cooling. A cascading failure is a failure of interconnected parts in which the failure of a single part can trigger the failure of successive parts.
