Crazyflie not turning on, on/off power button

Hi Guys,
Just assembled my crazyflie via setup steps. I keep pushing the on/off button with my finger but it doesn't turn on. Wondering if I'm just not pushing it correctly? When I connected it to the USB, two of the opposite diagonal propellers will spin and then stop, so I assume it's working.

Hi thetinyquad
I experienced what sounds like the same behaviour, once i plugged in the usb, while having my battery disconnected.
Are you sure that your battery is connected and that it's charged?

Hi, thanks for the help!
Charged it for about 45 minutes today but still didn't turn on. The battery was connected to the PCB when charging.
I did find this thread though:

Multimeter doesn't show a reading so seems to be a dead battery. I will contact support.

The battery PCM circuit has most likely gone into under-voltage protection mode. Normally it should exit this mode when charging is applied to it. As a first step let it charge for a full day and hopefully the battery charger on the CF2 can wake it up.
