As I connecting my adaptor with laptop, adaptor light start flickering and laptop is not charging. When I plugged off adaptor from laptop then adaptor light is on as normal.
But when connected to laptop it's Start flickering again.
Does you laptop boot up just fine? First troubleshooting step you want to do is to identify first if it's the battery or the AC adapter. If you have an available AC adapter to try with your laptop please do try it first. Another step you want to try is to remove the AC adapter and battery off the laptop then press and hold the power button for 20 seconds. Plug just the AC adapter back in then power it on and if it turns on put the battery back in as well and see if it works just fine.
