I have an asus transformer that I've had about 4 years. Just a few months ago, I lost the charger but just recently found it. Yesterday I plugged it in to charge but the light never came on which is something I always had a problem with but it would always still charge. I thought by today it would have been charged and ready but it won't turn on. I have no idea if it is even charging or if it's charged but the screen doesn't work or if my tablet in general took a $@$*. I tried holding the power button with the volume up bottom and holding the power button but nothing seems to work. Any suggestions?
