I purchased Acer aspire 7 i5 12th generation in August. From these past months it is working fine until yesterday. My laptop suddenly started lagging when Battery level went below 30% and I was unable to use even google chrome properly. I also noticed that the CPU Speed got to 0.32ghz, sometimes below but never increased. As soon as I plug in the ac adapter, the laptop starts to work normally again but started lagging again when I unplug the ac adapter. I tried changing power options and also tried to reset battery with the help of battery reset pin hole but still no improvements. I tried to update bios but bios is on its latest version. What should I do in this situation?
