Reset Button
Press the “RESET” button continuously for more than 5 seconds to load the factory default
configuration. After loading the factory defaults, the system will reboot automatically. The System
Ready LED will blink for the first 5 seconds. We recommend that you only use this function if the
software is not working properly. To reset the Linux system software, always use the software
reboot command (reboot) to protect the integrity of data that is in the process of being transmitted.
The reset button is NOT designed to Hard Reboot ThinkCore W300 Series products.
ATTENTION
Reset to Default preserves user’s data
Resetting to factory defaults will NOT format the user directory and erase the user’s data. Pressing
this Reset button will only load the configuration file. All files in the /etc directory will revert to
their factory defaults, but other User Data will still exist in the Flash ROM.
This function only takes effect when the user directory is working correctly. If the user directory
has crashed, the kernel will automatically load the factory defaults.
