I am beyond frustrated. In the past year I have been to the apple store at least 10x for issues with my MacBook Pro. First I had the logic board replaced due to the screen randomly shutting it self on and not coming back on without a hard reset. Then started my power supply issues. I went in about 5 times about the chargers not working. they replaced my power cord i think 3 times. and one time reseting the power management (i think thats what its called) and then they replaced the logic board a second time. Now my computer is running horribly slow, I'm getting beach balled all the time. And about 2 weeks ago the power cord stopped working again, they gave me another (AGAIN!), I informed them of my battery issues (charge lasts 2-3 hours tops with normal web browsing) they said they could find no issue with the battery. It seems like the battery has been getting worse. I checked coconut battery today and it read 72% capacity at 312 Cycles and the computer is telling me to service my battery. So I have to make ANOTHER trip to the apple store. To fix something I told them there was a problem with 2 WEEKS AGO. *Sigh* Maybe I bought a lemon?
