I have a Predator 15 G9-593. Everytime its unplugged it just dies immediately. Every time I try to turn it on while its unplugged nothing happens. First 3 times I did try to turn it on, keyboard ligths up and dies then after the 3rd try pressing the power button while unplugged does nothing. Warranty is 2 months pass its validity sadly. Battery reads 100% and everything seems to be fine software wise. Not sure about the hardware though.
