I had an issue with my phone and resolved it, this is me sharing this particular error and solution.
First the Problem:
I had my ZL running low on charge and the next morning it would not react to anything.
  • pushing buttons (and a combination of buttons, like power+volumeup) did not work
  • connecting it to the charger
  • connecting to pc did not show the device or trigger a reaction (did not show up in device manager)
Solution A: Install a new battery (e. g. via IFIXIT guide).
Solution B (try on your own risk!!!):
Open the backcover of the device (i used the IFIXIT disassembly guide).
You dont need to remove the main curcuit board, you just need to disconnect the flex-cable of the battery shown in the picture below, the pink marker shows the battery connector (top right).

I bent the connector so that it was accessible with my universel charger, which looks like this

I connected the two marked connectors go to the + and - on the flex-cable of the battery and the charger signaled that it was charging the battery.
I guess you can use any universal charger of this fashion. Do not use your standard usb charger, it's dangerous!
After 10-20 minutes i reassembled the phone and was able to charge it normally, start it up, etc.

I'm no expert but this is what I think happend:
A completely drained and at the same time worn out battery did not allow chrging the divice. Mine was 20 months old. The phone controls the charging process I think, so maybe there was not enough power left for that.
I will be replacing my devices battery with a new one and I suggest the same I you have had the same problem.

I hope this helps :)
