Hello,
I have a Lenovo g50-70 and suddenly it showed that is not charging and after turned off. I previously had issues eith the charger which needed to be in a certain position inserted to charge. Anyway, I replaced the charger and nothing happened. I also replaced the charging port and still nothing. I assumed it is not related to the motherboard because it worked before turning off till the battery drained (few mins).
What could be the cause and what can I do? Warranty expired by the way

You could need a new battery, or the charging circuit on the board could be damaged.

so you change this dc jack ? https://www.ebay.com/p/Lenovo-G50-80-G50-85-G50-70-AC-D...

Test it with multimeter put it to your charger and test from other side do you get 19v to red cable pins? You might need pin to insert in the dc jack if your multimeter tips are not slim enough.

You can also test components after charging cable in the motherboard, closest resistors could of prevented motherboard from dying if theyre faulty

Hi, maybe it's just a fuse that blew on the motherboard.

I know what I'm talking about, so you seem to have the experience as well, but we have people from customer service who have no idea how to fix a laptop and respond with false answers on this website.

Wow, that was a tad harsh. Some of us have more experience than others with computers, alas people do make assumptions if you don't do things the way they would. Or make assumptions about who you are, etc. Personally my oldest computer is an Ottrona Attache (http://oldcomputers.net/attache.html) that I got new. Been in love with computers ever since. I actually still have the thing, and it still runs.
