As an IT Support person, I have come across all sorts of technological challenges. While executing my duties, I have opened up cases for desktops, servers, and laptops. Most of the times, hardware disassembly and upgrading is very straight-forward: open the case, pull or add module(s), and close the case. However, not all hardware is the same.
At one point or another, I have had to open up a laptop to troubleshoot an issue. Like all sensitive equipment, it requires that special attention be given to all the small parts, otherwise irreparable damage might cause the laptop to stop working. For that process, I tend to make sure to separate screws based on their respective parts. Also, I tend to take pictures of every process that I take, so as to be able to backtrack myself.
Recently, I was given a laptop to troubleshoot an issue. It is the Apple MacBook Pro A1278. This particular unit was released several years ago, around 2010 or 2011. Despite the passage of time, the laptop looks very shiny and sturdy. The unit powers on, without any issue, and the user account is accessible. At first impression, anybody would say that Apple manufacturing makes sure that their products are made to last. Of course, as with any equipment, it matters how the user is treating it.
Back to the A1278, I need to extract the hard drive in order to connect it to an external unit. Also, I needed to pull the memory modules in order to try to bypass the firmware password. So, I proceeded, carefully, to extract all the small screws from the laptop casing, and put them in a cup. As soon as I opened it, I got reminded of the issues in dealing with Mac laptops.
As I said, I needed to extract the hard drive. But, in order to do that, I would have to extract the battery (WHAT???!!!). That battery extraction required that I unscrew it, and pull the cable powering the laptop. All that I had left to do was pull the hard drive. Well, that was my immediate thought.
As I am pulling the hard drive from the laptop, I am reminded that there is a widget that is holding the drive, and that I must unscrew that, as well. Having done that, I was able to extract the drive, and do what I needed to do.
Previously, I said that I needed to extract the memory modules. Well…guess what?! That procedure required that I unscrew a widget, as well.
Having troubleshoot all the issues that I had on my list, I proceeded to reassemble all the modules in their correct place. Having placed the last mini screw on the bottom cover of the laptop, I was overjoyed with a sight of relief.
Upon reflecting my time dealing with the Apple MacBook Pro A1278, I came to realize that dealing with hardware-troubleshooting requires a lot of patience. Some laptops are easy to get into, and others require that you dedicate more time into them.
Overall, patience and practice brings perfection.
