From my understanding, permanent red light (when plugged in) means the phone is getting juice but it is unable to detect a battery present. Have you cleaned the battery terminals? Even if the phone is dead somehow, (which after 4 years of use and abuse I managed to kill mine) the phone itself still charges the battery when plugged in and shows the orange light when charging, if you have red, it isn't charging the battery. The phone wont do anything if the battery is fully discharged, so if the red light is stuck on when plugged in, you aren't charging the battery/battery isn't detected. Determine if that's the issue or we need to look elsewhere.

P.S. the phone won't be recognized by the computer when off, the phone also won't do anything else if the battery is fully discharged, literally nothing, no lights, no response to soft/hard reboots, nothing without a battery with some juice in it.
