Solved! Laptop Charger charges and discharges


Apr 17, 2016
My Lenovo Legion Y720's charger is doing something, I dont know if it's supposed to prevent the battery from being overcharged, I dont know.

While playing games, I use Lenovo's fan boost software, (I think that uses a bit more power), and when my battery reaches 96%, it goes down to 95% and says (plugged in, discharging), after some time maybe 1 or 2 mintues, it goes back up to 96% and repeats. Now, while writing this. its gone up to 97% and hasnt gone back down yet.

Theres also a glitch where the charger sometimes says 1minute from fully charged.

here, its gone up to 98%, and by the time im uploading this its already at 99%

Is this all just software issues? or am i gonna have to buy a new charger

My bios version:BIOS Version/Date LENOVO 4GCN38WW, 18/07/2018

I think the lenovo support webpages are down, I keep getting errors trying to access them.

Im not sure about this one but I think this is my OS version: Version 10.0.17134 Build 17134
