I have a Samsung S4 mini I9195. It was low battery so I pluged it into a USB cable to my PC . After an hour or so I checked it and it was dead, no biggie i'll just charge it at home. Put it on the charger and left it(sometimes the battery symbol takes awhile to show so I just ignored that it didn't show) however after 5 hours nothing. Again no biggie i'll work on it at work. Nothing, she's dead jim.
So I start trying to tackle the issue. I've done the button methods (two and three button methods that are all over YouTube) got a new battery, drained it, whacked the power button, dismantled it and check all the connections but it will not responded to anything or light up. It only responds to when a usb cable is plugged in, the PC acknowledges it by dinging and I can tap Morse code if I use the three button method at the same time. But I'm all out of basic options, and I'd rather not send it to a pro cause they'll probably tell me what I already know and charge me more then what I paid for the phone to do so.
Do you, the internet have any other solution's that I have missed?
