MacBook Pro Startup Beeps
Hi all,
I have a MacBook Pro 13 inch (Late 2011). I had upgraded my RAM back in December of 2012 from 4 GB (2x 2GB 1333 MHz DDR3) to 8 GB (2x 4GB 1333MHz DDR3 from Kingston). This summer the computer on startup began emitting 3 beeps randomly and sometimes on startup. I found where this is indicative of RAM issues and could possibly benefit from reseating the RAM, so I reseated the RAM. This seemed to solve the issue for a few weeks, but then it started again. Long story short this kept becoming more frequent, so I took the computer to an Apple Authorized Repair Center (there are no Apple stores close to me). They ran hardware tests and found nothing to be wrong. They suggested reformatting the hard drive as it could be a corruption in the OS X as I was running the El Capitan Beta. I backed up the computer and reformatted the drive reverting to OS X Yosemite. This didn't change anything about the behavior. I then filed a warranty claim on the memory and changed the memory out again. While the issue has happened less since changing the memory, it is still happening.
Has this been an issue for anyone else?
How can I go about fixing this?
Thanks for all you help!
MacBook Pro, OS X Mavericks (10.9)
