Thank you for your patience. Please unplug the power adapter from the Venture II and then hold down the power button for about 30 to 50 seconds or until either the power light turns off or until the device boots up. If that doesn't work you may need to replace the battery with a new one.
Thank you for your understanding.
Need power reset to shut off power light. Presently measuring battery leads at 3.99 volts. Discharging with a single led to drop battery voltage.
