My problem is similar. I haven't had this issue before. The charger
keeps disconnecting and reconnecting at random intervals when the
battery is full (and makes this annoying clicking noise, the sound of
plugging a socket into a wall). This doesn't happen when the battery is
charging and pc runs perfectly with the battery completely removed. It
also doesn't happen in Windows 10. My system is Ubuntu 17.10 (x64)
kernel: 4.13.0-25-generic #29-Ubuntu SMP Mon Jan 8 21:14:41 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux
I am pretty much certain that my charger is working correctly.
I'm not sure this problem is also related with the kde-workspace
(Ubuntu) package. My machine runs on Unity 8.
The lshw output of my system(This is while battery removed):

Bug description:
Since upgrading my Samsung 540U4E-K01AU to Kubuntu 14.04 the battery
charger keeps connecting and disconnecting as i change from
application to application or another tab. It doesn't drop out if im
not interacting with the laptop. I have tested the charger with a
multi meter and the charger is physically working correctly. I didnt
have this issue with Kubuntu 12.04, 13.04 or 13.10. If i boot from my
tails live cd it seems to work fine.
