If your RokBox MC Mobile Laptop will not power on:
The first thing to do is to ensure that your power supply is plugged-in and to check all cables.
Second, look on the front of the laptop for a green or amber charging LED. Do you see these LEDs lit-up?
If you do, leave the laptop charging for at least an hour.
Then, try powering it on.
If it won't power-on:
Unplug the power supply from the PC.
Hold the power button down for ten seconds.
Leave it unplugged for 30 minutes.
Plug it back in, and see it if powers-on.
If it does, then the issue was a brief power management issue.
If it does not, the laptop needs to come back for repair, and we can organize that for you. Please open a support ticket to request an RMA.
