Battery not charging at times but works after fresh start

Battery doesn’t charge (though it shows the charging symbol, the % goes down)
But if it shutdown and start the laptop, then the charging works fine… (so the hardware seems fine)

Started observing this yesterday, 3 times in last 24 hrs (my last update was 4 days ago)
I put my laptop to sleep most of the time rather than shutdown

below is the tlp-stat output while its working (should have taken a copy before restart, will do once i see it again)

    ~  sudo tlp-stat --battery                                                                                                                                                         ✔

I have the same problem, also on a Lenovo laptop.

mine is ideapad 5, how about you

i think its happening because of the usb c port i use for charging, may be it gets disabled when the laptop goes into low power and hence not charging, but not sure though
