Hi I have a MID ANDROID tablet. Its 7 inch mod. My initial problem is that I cant't switch it on, the power button is broken and the power switch on the mb has come loose totally. Is there any other way to switch it on?? When I connect the charger the tablet pc starts to charge and shows the android battery charging icon mid screen for a few seconds then black screen. I was told to connect the USB to my macbook and that should power it on but it doesn't, just charge sign again. I really need to get this working ASAP and will only open and solder the button back on the mb when I know its working. Please help me with this if you know how to power it on without using the button. Thanks for reading.
