Wi-Fi module "mod"

IT stuff Oct 9, 2020

Grandma got a new laptop, her laptop from ~2008 simply didn't have the resources to run stuff in 2020.  
Her replacement laptop was also not new, but a big upgrade and very usable in the next few years.  
The downside - it did not have a Wi-Fi module. It originally came with one, so adding one wasn't a problem, but I totally forgot to source one.  
Not a big of a problem, the old laptop had one that would work just fine.

Or so I thought.  

The new laptop had a smaller cutout for the Wi-Fi module, where the old laptop's module would not fit into.  
Usually that's a problem, since normally the Printed circuit board (PCB) are used completely - taking some off will result in breaking the module.  
But not with this one!

The top bit is see-through and doesn't show any traces of traces (hah) or other electronics. So it's safe to remove the see-through part.  

Now comes the fun part, removing the removable parts of the PCB!  
I used a grinding machine for this, the one in the background.

After a bit of back and forth with the module, this is what I ended up with. Some error of margin left, so I didn't accidentally removed too much.

And the replacement laptop was happy with the old Wi-Fi module!
