Question My Acer Nitro 5 stops charging after 87% HELP!

Jun 14, 2019
I bought this laptop in 2018 March. Recently I am having difficulties in charging the laptop to 100%. When i am gaming the charging stops and the keyboard lights up, and the game starts lagging. I have tried to detach the charger and then re-attach it, but it still stops charging when it reaches 89% or 90%. If i keep the chord attached it starts charging then again stops and then again starts charging. I need help as it's really getting annoying. It also doesn't shows the battery low warning, when i start charging my laptop at 14% of battery, the laptop shuts down and then i have to turn the laptop on and it shows that i have only 1% of charge. HELP!
