Trying to FIX a LENOVO CHROMEBOOK S345 with some Previous Funny Business

Remember that this is just for entertainment, and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.
