3 year old, had the exact same problem with last Lenovo Laptop. Where the charger plugs into the laptop it seems a bit loose and I have to constantly manually adjust the jack plug to gain a connection. When I do this it charges fine. Whilst I'm typing this I've had a look to see if any screws are missing/loose but they're all fine. I have just noticed that the hinge on same side of charger had bottom section of it broken off (I can hear something rattling about inside it). Which would account for every time the laptop gets opened it clicks and is loose. Would I be better off binning and getting a new one or is there a relatively simple fix? I'm not so tech savvy but I could try some basics. BTW I took this laptop to a repair shop last year for this issue and I got charged £40, the guy laughed and said oh it was a missing screw. Ever get the feeling lol.
