I've seen some solutions for my kind of problem but none of them seems to start at my frustrating point.
After I rooted my HTC One S I was able to reboot my device and everything went fine.
The problem occured just when my battery was depleted and the phone got turned off I had no chance to restart it.
The LED did not show me it was charging and it did nothing, when I pressed the power button or the volume/power combination.
So i connected it to my laptop and tried to check my devices through adb.
It says my device is in recovery mode.
Using the fastboot reboot command I was always able to reboot my phone and everything was just fine.
I thought it was alright, as I just had to pay attention not to use up my battery, when not at home.
Today my phone just decided to turn off. It refuses to boot up even with the fastboot help from my PC.
It just says: < waiting for device >
certainly I'm unable to post a link to a screenshot I made of my cmd.
Thank you for all kind of help
