I have an Acer Aspire E15 E5-576G. Weeks ago the battery suddenly died, it had been working fine before and could hold for more than 2 hours. The charging led would be on for about 30 seconds or longer then off if I plug it in. Can't charge it whatsoever, it says "Battery not present". So I guessed I could use it without a battery, but I was wrong. Now I'm experiencing stuttering in games despite having power plan set to maximum performance and everything else. FPS dropped to half of what it was before. It's supposed to be just like before since I always plugged it in, but it's not.
I don't understand how this could happen. Does this series of laptops run worse without an active battery or something? Any help would be greatly appreciated. Thank you.
