Looks like one of those recorded message things you find inside greeting cards - the glob of stuff below the black epoxy blob (the ic), looks like a badly corroded button.
Can try cleaning the button up a bit, or removing it entirely, and bridge the connections beneath it.
I’m thinking this would be the case if your instance had more than 1 user subscribed to that community in the large instance - but if it is just you, wouldn’t it be similar to accessing each instance and viewing the communities there?
Think this is more of a pipe-dream though, considering that 10 years is a long time for PC interfaces and internal interconnects. Swapping between different laptop manufacturers will be unlikely to happen, I feel.
Framework allowing for the whole mainboard to be replaced seems like a good halfway meeting point, and each case size being a constant chassis that hopefully will be supported for a long while.
Hope that other manufacturers follow suit, and at least have their own lines of upgradable laptops.
Perhaps you could share what is the model of your thin client? So we can get a grasp of what we’re dealing with.
