I had a Ring Pro that was a few years old. It died. I would log in to look at something only to find it was alive a day or two before then died. Then miraculously it would come back to life only to die again.
I bought a new Ring Pro to replace it and documented that process here. It was a living fucking hell. It should have been easy. But it was not easy. Enough of that. I spouted off enough about it in the last blog entry. Let’s talk about fixing the one that was broken. This will just cover the battery replacement and not the entire tear down or rebuild.
Basically you just open the thing up and remove the motherboard. There are several connectors on the board which must be CAREFULLY removed. Take a picture first before you disconnect anything. Regarding the connectors, just get under them and pop them up with a spudger made of plastic. THEY ARE FRAGILE. Then remove two screws , pull the speaker out and then lift the motherboard.
