Why is my laptop discharging when playing intensive games even if it is plugged in?

KRcsa

I have an Acer aspire e5-576g-59ab, it's new, it has only 4gb of ram so i bought a 4gb extension... ican now play dota 2 at ultra settings and i was happy about it but then i noticed that after time of playing my battery discharge even though its plugged in ..at first i let it discharge cause i thought it was normal..but then my battery get uncalibrated so bad that by reaching 70% the laptop suddenly turns off when on battery mode.So now i bought a new battery and it is still happening... it discharges even if it is plugged in... i'm scared that i may be able to break this new battery...help

Also im using a 90 watts acer charger cause the one that comes with the laptop can only give 65 watts

You won't break the new battery by discharging while plugged in. Try uninstalling any non-Microsoft virus scanners, Microsoft Defender and MRT is all most people need. Also if you have any programs/apps running in the backgrouind that you aren't using, try disabling them under the startup tab in task manager. Then shutdown. Turn machine back on. Jack E/NJ
