i would really recommend to get a new one
Kahit galing po siya sa SG?pa check mo paps sa dell mismo para sure na maka-help
gaano ba sya kadalas magshutdown ts?
Nag shushutdown rin po.hindi ba namamatay kapag naka charge?
Nagana naman po siya.check mo ung FAN kng nagana ba sya o ndi.
Opo natry ko na pero nagshushutdown pa rin po sya.did you try to remove the battery and then plug it to see if it shuts down?
Also checking if the fan works is a good idea, and cleaning the heatsink (the holes for air)!
