yeah as per the title, its weired issue, i will get to the point :

my laptop when its 0 t0 50% = it doesnt charge even if plugged in ( well it does charge when move it arround or on my arm and unplug then plug again, but when does charging i wont move my laptop), once i move it little bet it will stop charging (icon doesnt show charging )

but when its 60% or above, it directly charge without any proper or doing anything, even moving the laptop around its still charging !!!y

any explaination ?

i got the laptop 2days ago ( its refub), and first time when charging it there was no slight vibrating buzz over my laptop ( i alway had it on my all prevouse laptops ) but now it started feeling it..

my question, what cause this ? ( i am pretty sure its not the JACK) should i consider bring it back to the shop to check out ?
and my 2nd question having this slight vibratting buzz over laptop (its leakage electrecity) any harm on my laptop mobo or ?
