I am using a three and a half year old Lenovo G50.
It was working fine 2 days ago and this problem started yesterday. The batter can last about 40 minutes to an hour if fully charged.
The hinge is loose, I glued it on and the charging port also is slightly loose. When I plug it in, it charges normally when off. However, I cannot charge the machine when it is on. It says "plugged in, not charging".
What can I do?
