Hi!

And for about few days I have a little problem
My battery is charging but after getting to full charge, it still keeps charging and it says "100%, charging"
And after I close the laptop, it keeps the green light for the battery green and after a few hours it just blinks orange and green like is charging and discharging.
Hope you cand help me!

Thanks in advance and sorry for my english! 😀

Thanks for your answer
The adaptor is good because the laptop is working without the battery
I will try a full discharge and then a full charge and if it doesn't work, I will try your solution
