Plugged charger in to the unit, the LED on the charging cord did not come on and the laptop is not receiving any power. Went to the Apple store and tried one of their chargers and got the same result. no power to the unit. the salesperson at the store immediately stated that the logic board was the issue. at $500 for the logic board, the unit is clearly not worth repairing. If I have eliminated the charger as a possibility, does the mean that it is definately the logic board that is the problem or are there other possibilities Any help would be appreciated, It seems to me that an $1600 laptop should last more than 4 years and that a charging issue shouldn’t cost more that the unit is worth to fix. thanks
Download this little gem of an app: coconutBattery. See what it tells you is going on. You may also want to reset your SMC. Follow this Apple TN on how to do that: Intel-based Macs: Resetting the System Management Controller (SMC). Let us know what you discover. Update While its possible the main logic board is having a problem with the charging FET and/or comparator circuits. It would be wise to make sure the MAgSafe connect block is working correctly. See if it dirty or damaged in any way on both the cord and the system. If you want to take the gamble I would replace the CD-In board unit. Its a bit of work to get to as you’ll need to take the logic board out. but in the process you should be able to inspect the FET’s if they are burnt.
