Hi! My nexus 7 had been sitting inactive on my shelf for a few weeks and last night when I plugged it in, it no longer seems to charge. The screen flickers for half a second and then goes black. It won't start with the power button, however it does start giving of a quiet electrical sounding buzz after trying to start it. There also seems to be a burned/parched smell to the device. Something seems to be fried. Unfortunately, the device is rooted and has a custom kernel, so I'm going to assume that when send it to warranty and they fix it and then boot it up they are going to declare the warranty voided and charge me for the repairs. To me it seems that my nexus is done unless I'm willing to pay for the repairs. Any advice?
