Zero Insertion Force



I can remember when laptop computers had clip on batteries that were easy to exchange. Then the fashion slipped towards thinner types where the battery gets spread around the innards of the machine. Apple is a case in point with their MacBooks, which contain six slimmed down batteries linked together.

Cue the Right to Repair initiative in Europe, which affects white goods costing, say, £400 but doesn't extend to computers costing, say, £1000 plus.

Then think of the parts in a computer requring renewal. 

The most obvious is the battery, which will become less effective after about 200 duty cycles of charge. It wouldn't be too difficult to have a plug in battery connector so that even a fiddly 6 part battery could be changed, but that would be too obvious. 

Instead the machine has a threaded battery woven into the motherboard, and it sends data to the computer's motherboard along a 6 line cable with is about as thick as a magnetic recording tape (ie thinner than paper). It plugs into a Zero Insertion Force socket on the mother board.

It is not designed to be end-user serviceable, instead requiring a costly visit to the main store to get the battery swapped over. 

Note the S-shaped thin tape which is part of the battery replacement process. 

Right to repair? I don't think so.
