Perhaps take this with a grain of salt since I’m not a laptop repair expert, I have only fixed my own laptop and phone when their screens have broken (but I was successful, if that makes a difference).

I just performed a charging port replacement on my Lenovo IdeaPad S340-15IWL today, and referred to these instructions a little. However, I believe these instructions can be greatly shortened, which saves time and eliminates unnecessary risk (assuming I’m actually correct about this). I found that the only steps I had to take to replace my charging port (and its cord) were to open up the back of the laptop (your steps 1 & 2), unplug the battery (rather than remove it entirely), flip up the hinge overtop of the charging port (step 21), unplug the charging port (step 23), and take out the charging port and its cord (step 25). I didn’t do any of the other steps, and so far my laptop is still alive and it charges! Knock on wood. I hid the extra cord underneath the motherboard w/o removing the motherboard. But, great photos!!!
