There is loose connection issues when I connect the power chord to laptop. I left the laptop ON while it was not charging, so the battery is discharged now. The laptop should start based on power chord, but because of loose connection I am not able to start it. Can you please suggest what steps I should follow to fix it?
Note: I am using this laptop since last 3.5 years, so it can run on battery for around 1 hour or so.
