I bought this a year and 10 days ago and in the last month or so the battery began to give me trouble when I plug it in to charge.  It doesn't charge about 1 out of every 3 times I plug it in to charge.  Have to plug and unplug it and several times and make sure it's charging before leaving it or often I will find when I come back to it that it didn't charge.  This occurs with both usb-c charging ports so either it's the charger or something internal. I have followed advise to clean the usb-c port and charger plug without any change.  I went to Lenovo's site and put in for a repair and was told to take it to Best Buy who are authorized to repair it.  Unfortunately I didn't realize how close the warranty was and it expired before I got it there.  I have read that usb-c charging has inherent issues with charging so I'm not sure if this is Lenovo's fault of just the nature of it.  My opinion otherwise about the laptop is also is that it's just ok.  My complaints are that it is too heavy, slippery to hold, it's hard to open the lid, the screen is dim and way too glossy, and the speaker, for all the hype are just mediocre.  Also the lack of an HDMI and card reader are also big drawbacks.  The battery life is decent though and I was very happy with this when I first got it but now I expect to throw it away if it stops charging completely as I don't think it's worth investing money into given it's shortcomings.
