Chosen Solution
I have a 13” late 2010 MBA. It was giving me some trouble, so I took into a local certified Apple service center (I live in central Mexico). Two things were identified as “fail” during their diagnostic tests. (1) Full System Diagnostic (OS) - exhibiting problems with the SSD (Drive Block Read), and (2) Full System Diagnostic (EFI) - faults during tests of the memory and SSD. They said they don’t have a source for a new logic board for my computer since it is so old. I am assuming that I could solve these problems myself by replacing the logic board with one purchased through iFixit and replacing the SSD with one from either iFixit or OWC. Am I correct? Also, I’m not sure which processor I currently have. The only logic board currently available for my computer through iFixit is the 1.86GHz model. Does it matter which processor I choose?
Yes, those should solve your issues. Are you sure their tests indicated a problem with the memory (RAM) specifically though? If it was only the SSD you wouldn’t need a logic board replacement. Processor speed affects just that, the speed of the processor. I would say you’re probably fine with the one iFixit sells but it depends on your workload. Honestly however, I probably wouldn’t go through with the repair, personally. ~$300 for a logic board and SSD is a lot to drop on a 2010 MBA, when you could get a 2012+ MBA for $300-$400 that will work with the latest software updates (Mojave), etc… The 2010 is pretty near its end of life in general.
