JLAB PRO-7 Troubleshooting

When cable is plugged in, charging symbol is not shown

Defective Charging Cable

• Replace the charging cable with another micro USB cable. If the tablet begins to charge, then the original cable may be faulty.

Charging Port is Clogged

• Check the charging port located on the top of the device for any debris. Lint and other foreign material can clog the port and prevent the power adapter from fully connecting. Clean with a small cotton swab to remove any debris.

Tablet powers off sooner than it should

Multiple Apps Open

• Having multiple apps open will drain the battery of your device faster. Tap the home button twice fairly quick to view all open apps. Close out apps by swiping them to the right.

Faulty Battery

• Check to make sure the light appears on the power adapter and the charging port is clean of debris. If the tablet only powers on when the power adapter is connected, the battery is faulty.
