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 ✔
