jamesVic

Hello there, I am Nitro 5 AN515-52 user for 1 year, my laptop was fine until one day, when i plugged my laptop with my charger, the laptop began charge and then discharge itself, its like the charger is turned on and then one second later turn off, and like that for few times before it entirely cannot charge my laptop. However, when i turned of my laptop, the charger able to charge my laptop. Then i tried to turn on my laptop, and my charger unable to charge my laptop again.

I tried to swap charger but it doesn't work. Also i recently update my BIOS to the latest (1.28)

What can i do to solve this problem?

Thank you.
