Troubleshooting

If myPower ALL Plus does not power the portable device or charge the device battery, take these steps:

1.Verify that the battery is turned on by sliding the power switch to ON. Please note that with some laptop models, the laptop may shut down if the laptop is connected to MP3700 with the power switch in the ON position. Remove and replace the laptop battery to reset the laptop charging circuitry, and connect MP3700 again with the power switch in the OFF position. Slide the power switch to ON after the laptop is connected.

2.Verify that the current consumption of the portable device is not more than 5 Amp. If the device consumes more than the maximum provided by myPower ALL Plus, the device will shut down when turned on and cannot be powered and/or charged by myPower ALL Plus.

3.Verify that the device does not require more than 20V or 90W (=voltage x current, which is shown on the power adapter).

4.Verify that the laptop power adapter does not provide more than 5A. The output voltage can be found on the power adapter label.

5.View the remaining battery capacity. If it is below 25%, recharge myPower ALL Plus.

6.Check that the output cord is connected to both myPower ALL Plus and the portable device, and that the adapter tip fits snugly into the power jack on your portable device. If not, try another adapter.

7.Verify that the polarity of the device power jack is Center Positive. If the polarity is Center Negative, please contact support@tekkeon.com for assistance.

8.Verify that a battery is installed in the portable device as some devices will not function without a battery installed.
