I start detaching the cables from the Logic Board and then remove the fan. At any rate – I find that the iFixit site has a beautiful step-by-step guide for logic board replacement. I figure that it can’t be that hard to take things apart (it’s the putting back together that can get ya – ha!). Now, if you have never ran across the iFixit website, I have to say…what a gem! So I take the back cover of the MacBook Pro off again.

We need to address the 3-Beep issue, but also I figure while I’m at it – let’s see if I can figure out what’s up with the fan. My son does some gaming on his MacBook Pro, and I’ve always mentioned to him that his fan seems to be running really ‘hot’ – so I decide to kill two birds with one stone. I hand the laptop to my son, and then several minutes later - it powers off and starts beeping again. The Mac recognizes both pieces of memory, and all seems well. I swapped the memory in a couple minutes and then it powers up, we can log into the laptop – and all seems well. Apple’s support site has a nice article with explanation on how to swap out and replace memory at the following support link: As such, I’ve got some additional RAM at the house and figure I’ll just swap out the RAM to rule out any bad memory. My daughter’s also got a similar 13″ MacBook Pro for when we got it for her for college. If you have never swapped out the RAM in a MacBook Pro before, the process of doing so is actually quite easy. A bit research reveals a couple of good tips from Apple’s own support site:Īfter review, I think easy enough, I’ll just swap out the RAM. Interesting!Īfter getting home from work and a bit of investigation on-line, it was pretty easy to determine many others have run into the same situation. In addition, it would beep pretty loudly 3 times, and then stop and beep again. The symptoms presented were that the machine would be booted up, and working just fine but then the screen would kind of go ‘green’ and have a bunch of horizontal lines on it.

My oldest son had texted me at work and told me that his Late 2011 model 13″ MacBook Pro laptop wasn’t staying powered on. I had an interesting situation present itself earlier in the week.
