So my moms been watching movies online with my laptop then one day it just shut down like literally. We've tried charging it, removing the battery with the charger still plugged suspecting it was the battery but it wasn't, set everything back. I did the hard reboot, the 30-60 second power button trick with and with out the battery, it turned on one time and it went all the way to the home screen after logging me in then died out again. I left it charging a while again and tried and it seitched on but then died out again. Please help me. Mine is an HP Pavilion model number 15-n211nr. Thank you in advanced.
