Acer Aspire F5-573 shuts off randomly
My Acer aspire F5-573 lost its warranty 2 weeks ago and it now keeps shutting off randomly. I'll explain.
When the laptop is unplugged it will turn off at random moments. Sometimes it will have 95% battery left, other times it has 40% battery left. Also it turns off at random times. Sometimes it works for 5 minutes and other times it works for over an hour. It just randomly shuts off when its not plugged in.
I have checked the temperature and it is not shutting down due to overheating. Also checked the screws to make sure battery isn't loose. I also checked the advanced battery settings and those were set properly. Anyone have any ideas on why it shuts off randomly? I'm very upset that it started happening right when warranty stopped.
