Turns out the mangled gold-tipped clamshells in those antenna connector tips may NOT have been irreparably destroyed. Today I went back in and looked at the connectors that didn't quite mate with the pins on the BT/WiFi board, and with magnifying spectacles it appeared I might be able to spread those two leaves apart. I did so with the smallest jewelers screwdriver I could find, and after doing so I managed to get both damaged connectors to seat onto their mating pins on the Comm board. AND, BT is BACK (even to the level of streaming to my AirPods Pro earbuds!
Having just learned that I'm too old and too clumsy to be doing this stuff, I turned to your excellent teardown photos and learned that the CPU itself can be upgraded! So, now my VERY deeply buried bipolar disorder has me considering just what I might accomplish by upgrading from my Quad Core 3.4 GHz Core i5. Given that I'm already using a processor-direct slot 1 TB NVME2 SSD stick for my boot/data Catalina volumes and have quadrupled the RAM to 32 GB (and since the new 24" iMac's display would be wasted on MY 74 year old peepers, could anyone comment on the possible performance enhancements I'd see with a CPU chip upgrade? I see that staffer Jeff has upgraded his to a core i7; is there a non-tweeting way to pose a question to him?
GREAT resource, this, even though what it does is tempt me to attempt things I shouldn't be doing . Evidence of THAT is that once I'd secured my screen with fresh painters masking tape and booted her up I discovered that I'd not re-attached the display power and data cables ?
Cette réponse est-elle utile ?
