My iphone 4s wouldn't switch on?
My iphone 4s was in the cupboard for about 2 weeks unused, and then when i tried switch it on, it's not working. When i plug it into the power adapter, only the backlight comes and stays for some seconds and goes off. It happens again and again, time to time. I checked if the LCI's are activated, but no. I also tried to reset it by holding the Home button and the Sleep/Wake button together, still no luck. What is happened and what can i do
