I tried almost every mattered posted on the website such as SMC, reset PRAM but I still couldn't resolve the problem, after that my battery percentage went down to 7% and my battery is not charging!!! Is my battery died and needs to be replaced a new one? Any advise would be very much appreciated.
Thanks & regards
