Computers and network devices can be very temperamental. Here is a list of quick fixes that could solve your problem for free.
- Reboot - If you have not rebooted yet, try this first. Reboot through your operating system if possible. Just unplugging a computer or powering it off with the power button can cause data loss.
- Power discharge - This solves a lot of boot and power on problems, if your device does not have a battery or if the battery is removable.
- Power off the device
- Unplug the device
- Remove the battery if applicable
- Hold down the power button for 20 seconds
- Reinsert the battery
- Plug the device in
- Power on the device.
