It's probably time to take it to a repair shop and have the troubleshoot and repair the plug/jack on the laptop.
Hope this helps.

My Asus laptop has gone through four chargers. The original first developed a loose connection and without opening it and rewiring, it's impossible to fix it. The other three were replacement chargers I bought that matched the laptop's voltage and whatnot. The second and third charger burned out in the power cable part. The fourth one shows the blue light but is not charging the laptop. I am so tired of buying chargers and want a sure fire fix. Is it a problem with my laptop? I do notice that the metal casing would give me electric shocks every now and then when it was charging, ever since the first original charger. What should I do
